Tapojärvi kicks off open-pit mining contract at Kaunis Iron

Tapojärvi Sverige Ab recently began a new contract mining gig at the Kaunis Iron mine in Pajala, Sweden, at the same time as the temperatures in that region plummeted to around -40°C.

The service contract with Kaunis Iron covers machine work in ore production as well as production support work, which includes all open-pit production activities other than rock transportation, drilling and charging.

Miika Miettinen, Production Manager at Tapojärvi, said the contract began as agreed on January 1, with the company compiling a service package in only six weeks.

The start of a new service contract requires new personnel and equipment to carry out production in line with the contract. Additionally, production control systems, infrastructure, offices and production facilities, as well as maintenance services, are needed. A mining contractor must also consider safety at every step of production.

Approximately 60 new employees were recruited, and additional personnel were borrowed from other Tapojärvi sites, to bring this contract in within the six-week timeframe.

Miettinen highlights the professional mindset of his employer, skilled and committed personnel and new equipment as Tapojärvi’s strengths. These factors enable Tapojärvi to respond quickly to the client’s needs.

“We were forced to let the production stand idle when the temperature dropped low in early January,” Miettinen said. “There were also some struggles involving the machinery. Despite everything, our operations have been launched successfully and the client has been happy with our performance.”

To support its operations, Tapojärvi has developed processes and systems that are constantly collecting online production data. Data and analytics help enhance Tapojärvi’s performance, safety and maintenance processes.

“We are able to provide the client with comprehensive and complex production data, which allows us to influence the mine’s operations and performance together with the client,” Miettinen said. “I am glad that our cooperation with Kaunis Iron has gone smoothly from the very beginning and that we are already involved in developing the operations.”

The service contract with Kaunis Iron is Tapojärvi Sverige’s first major open-pit mine contract in Sweden. The company has previously worked in underground mines on the sites of LKAB and Zinkgruvan, for example.

LKAB to bring GHH LF-19EB tethered-battery electric loader to Malmberget

LKAB is set to add to its electric fleet at the Malmberget mine in northern Sweden after agreeing to acquire a LF-19EB tethered-battery electric loader from Germany-based GHH.

The manufacturer welcomed a team of LKAB team experts to its factory and testing ground in Gelsenkirchen, Germany, this month, with a successful Factory Acceptance Test of the LF-19EB taking place.

The LF-19EB is a 19-t-payload LHD initially designed for feeder breaker loading in the soft rock, salt and potash mining industries. It has a 34 kWh on-board battery for panel-to-panel electric tramming, with a tractive effort force of 380 kN and an average of 250 kVA under permanent load and 315 kVA peak. It has a maximum cable length of 310 m, which provides loading flexibility when plugged into the mine grid.

The loader heading to Malmberget has been upgraded for hard-rock applications with input from the customer, GHH says.

LKAB has tested and used several pieces of battery-electric equipment from different vendors at its Malmberget mine, while its Kiruna mine was among the industry’s earliest adopters of cable-electric loading, trialling its first Sandvik unit in 1985.

LKAB bolsters automated, electric Sandvik loading fleet at Kiruna iron ore mine

LKAB has ordered 12 Toro™ LH625iE cable-electric loaders and five Toro™ LH621i loaders, all equipped with Sandvik’s AutoMine® solution, for its Kiruna iron ore mine in northern Sweden.

The order will more than double Kiruna’s electric Toro LH625iE fleet to 20, all of which will now be automated, and its total Sandvik loader fleet to 28 by the end of 2025, the OEM said.

The orders were booked in the June and December quarters of 2023, with deliveries scheduled from January 2024 through the end of 2025. The investment follows a study by Sandvik’s Trans4Mine team and calculations by Polymathian that identified opportunities for Kiruna to increase production by as much as 15% through automation of its large electric loader fleet.

“Sandvik and LKAB have a shared goal to boost production at the Kiruna mine,” Magnus Backe, General Manager LKAB Kiruna, said. “This is a true partnership to increase tonnage and improve safety through automation.”

Developed in 2020 as a collaboration between LKAB and Sandvik to replace Kiruna’s ageing fleet of 17 Sandvik LH625E loaders, the 25-t-payload Toro LH625iE is a revamped version of the industry’s largest-capacity underground loader.

“This investment supports our strategy towards a more electrified, autonomous and safer mine,” Joel Kangas, Mine Manager at LKAB, said. “We need to excavate an enormous volume of rock from depths of up to 1,300 m, and we will mine even deeper in the future. These depths present a prohibitive ventilation challenge for conventional equipment of the size we need to meet production demands. We worked closely on a daily basis with the Sandvik experts on site to ensure a seamless implementation.

“Ever since we put the first Toro LH625iE straight into a production environment more than three years ago, these loaders have been the backbone in our production system, exceeding our expectations, and we look forward to incorporating these new automated units into our operation.”

Kiruna was among the industry’s earliest adopters of cable-electric loading, trialling its first Sandvik unit in 1985. The oldest of Kiruna’s Sandvik LH625E loaders was 13 years old and had more than 40,000 production hours when what began as a project to modernise the loader and a side project to enhance its cable reeling system ultimately evolved into a completely upgraded loader model with the latest technology and new components.

Sandvik collaborated closely with LKAB to customise the design of Toro LH625iE to meet Kiruna’s needs. These included better energy efficiency than the original model with the same payload capacity and a larger, more ergonomic operator’s cabin with a turning seat that swivels 180°.

Mats Eriksson, President of Sandvik Mining and Rock Solutions, said: “[The] Toro LH625iE has proven itself at the Kiruna mine, delivering an unrivalled production capacity of up to 500 metric tons per hour. Not only are these automated loaders extremely productive, they improve underground conditions and operator comfort with less heat, fewer vibrations and lower noise levels. Our partnership will create value for LKAB for years to come, and we look forward to continuing to support LKAB’s goals to mine more sustainably and productively.”

The Toro LH625iE is 14 m long and features a 4-m-wide, 9 cu.m bucket and an energy-efficient, IE4 classified electric motor to deliver a low cost per tonne. It connects to Kiruna’s mine network via a 350-m trailing cable that enables an operating range of up to 700 m.

LKAB-DurocRail

LKAB invests in Ore Railway supply chain in northern Sweden

LKAB is looking to shore up its iron ore rail operations in northern Sweden by acquiring a stake and investing in new facilities for Duroc Rail AB.

The iron ore company has acquired a 49% interest in Duroc Rail from the Nasdaq-listed Duroc AB group, which retains majority ownership of 51%. The preliminary purchase price is approximately SEK75 million ($6.9 million), with LKAB also agreeing to invest up to SEK200 million to build a new industrial property for Duroc Rail at Hertsöfältet in Luleå.

Duroc Rail is a certified operator with unique expertise in wheel maintenance for locomotives and wagons with experience of the climate in northern Sweden, LKAB says.

The Ore Railway runs between the port of Luleå and the port of Narvik, passing by the iron ore fields in northern Sweden. Almost half of all goods transported by rail in Sweden and Norway is currently being transported on the Ore Railway, with LKAB’s volumes accounting for the largest share.

For LKAB, the Ore Railway is an integrated part of the production system that starts in the mine and ends at the steel and mineral customers via the railway and ports. High capacity and availability of the Ore Railway and rolling stock in the form of locomotives and wagons is therefore business critical.

LKAB said: “The investment is a further step for LKAB to strengthen its capacity and flexibility to meet the growing challenges of the Ore Railway. In the past year alone, LKAB has invested in a new locomotive workshop in Kiruna, ordered 100 new wagons and started major work to modernise and upgrade the IORE locomotives used to transport iron ore, totalling an estimated value of SEK600 million.”

Linda Bjurholt, Logistics Manager at LKAB and CEO, LKAB Malmtrafik, said: “Duroc Rail has unique expertise in wheel maintenance for locomotives and wagons. LKAB is entering into this partnership to ensure that Duroc Rail remains and develops its operations in Luleå. They are part of a larger system and a prerequisite for efficient and predictable rail transport. Rail transport is completely dependent on effective maintenance of the railway wheels. This is important for LKAB and other railway operators today, and in the future.”

The wheel maintenance business was established in Luleå more than 100 years ago. Duroc Rail currently rents premises from SSAB on Svartön, in Luleå, but due to SSAB’s planned transformation from blast furnace to electric arc furnace operations, which requires access to more land, the lease will not be renewed. New buildings, equipment, certifications and other measures mean that the move will be a major investment.

John Häger, CEO Duroc AB, said: “Duroc Rail needs new industrial properties, and with LKAB as shareholder we can ensure development and capacity for the future, where we see that the green transformation that is taking place will require more efficient maintenance of wagon and locomotive wheels. We will therefore continue to invest and develop our offering for all customers in the region. We are pleased that our more than 100-year-old company with 50 employees in Luleå will continue to develop.”

Within Business Area Special Products, LKAB is developing new businesses in addition to the iron ore production, such as industrial minerals for external customers, as well as key services such as concrete, drilling, explosives, rock work, mechanical-engineering services and maintenance for LKAB’s own operations.

Leif Boström, Senior Vice President Business Area Special Products, LKAB, said: “LKAB’s long-term strategy is to secure key services and products for efficient, safe, and sustainable operations. We work with partnerships and subcontractors, but also by developing or acquiring companies that have specific expertise, for example in managing supply risks. Duroc Rail is an important investment for us, it is a well-managed company with good development potential in several areas and will be an important part of LKAB.”

The transaction is formally subject to the completion of the property transfer for the new industrial property, which is expected to take place before the end of the year.

Boliden looks to strengthen biodiversity ties with Sarkanenä Sustainability Park near Aitik

In order to strengthen biodiversity and create accessible nature experiences for the public, Boliden has today inaugurated the Sarkanenä Sustainability Park close to its Aitik mine in Sweden.

The company’s aim is for additional sustainability parks to be introduced in connection with active or decommissioned sites, it says.

Åsa Jackson, Executive Vice President People and Sustainability at Boliden, said: “Mines inevitably have an impact on the environment and the local community in which mining takes place. However, by restoring the land or setting aside other land and initiating efforts to promote biodiversity, we can strengthen the overall natural values and contribute to long-term solutions for both ourselves and others.”

Boliden’s sustainability parks are areas within our land holdings consisting of forest land, decommissioned sites or land adjacent to active sites that can be opened to the public. The sustainability parks reflect the conditions at the site in question and will demonstrate the site’s history and Boliden’s association with it, historically, today and in the future, the company said.

A meeting place protected from weather will be available at all parks, along with nature experiences in the form of trails, playful elements, activities and more to learn about biodiversity. The information provided is also based on ecological, economic, socio-cultural and legal aspects, such as the natural values associated with the site and how these can be recreated and strengthened.

Sarkanenä Sustainability Park is located about 10 km south of Gällivare along the road to Nattavaara and includes, in addition to other features, a circa-2 km hiking trail with an experience trail.

Boliden Garpenberg receives Sandvik’s first automation-ready battery-electric Toro LH518iB LHD

Boliden’s Garpenberg zinc operation in Sweden has taken delivery of Sandvik’s first Toro™ LH518iB with AutoMine® as part of a 12-month collaborative trial of the new automation-ready 18-tonne battery-electric loader.

Considered one of the most modern mining operations, Garpenberg is the world’s most productive underground zinc mine and Sweden’s oldest mining area still in operation. The mine is now set to become the first in Europe to trial a Sandvik battery-electric loader, the OEM says.

The Toro LH518iB will support Boliden’s efforts to improve sustainability by reducing greenhouse gas emissions underground. The company’s climate targets include a 40% reduction of absolute CO2 emissions in Scope 1 and 2 and 30% reduction of Scope 3 emissions by 2030.

Jenny Gotthardsson, Garpenberg’s General Manager, said: “We are proud to be recipients of the very first Toro LH518iB with AutoMine. The unit has already undergone extensive factory testing in Finland and we look forward to really putting it through its paces now in our operation. We’re on a journey to reduce fossil fuel usage and CO2 emissions and increase productivity, and we are happy to work towards these goals with long-time partner Sandvik.”

The Toro LH518iB marries battery-electric and automation technologies. Building on the predecessor Sandvik LH518B, the Toro LH518iB features several design updates and significantly improved field serviceability. The latest version of Sandvik’s intelligent control system enables AutoMine readiness, and AutoMine compatibility will be available for Garpenberg’s Toro LH518iB in the March quarter of 2024.

The Toro LH518iB has dimensions equivalent to the 14-t size class, enabling it to fit in a 4.5-by-4.5-m tunnel. Its ground-up design, powerful electric motors and innovative electric driveline result in a compact size with higher payload capacity and increased visibility, Sandvik says.

Sandvik’s patented self-swapping battery system, including the AutoSwap and AutoConnect functions, minimises infrastructure needs and enables the loader to return to operation significantly sooner than ‘fast-charge’ mining BEVs, the company claims. The battery swap is performed by the loader itself, controlled by the operator in the cabin, without need for overhead cranes or forklifts.

Johanna Øygard, Territory Manager for North East Europe at Sandvik Mining and Rock Solutions, said: “We’re excited to see the productivity and sustainability benefits Garpenberg will gain from Toro LH518iB with AutoMine as we monitor the loader’s performance and production metrics over the next 12 months.”

In Mexico, Torex Gold is set to receive 11 Toro LH518iB battery-electric loaders as part of a 35-unit-strong hybrid fleet for its Media Luna project.

Anglesey Mining bolsters Grängesberg re-start plan with pumped hydro-energy storage potential

Anglesey Mining has entered into a memorandum of understanding (MoU) with Swedish energy storage company Mine Storage International AB to investigate conceptual plans and designs for a pumped hydro-energy storage project at the company’s 49.75% owned Grängesberg iron ore mine after mining ceases.

Pumped-hydro storage is a green-energy storage solution that uses water and gravity to store electrical energy. An underground mine can provide a closed-loop solution using proven, pumped hydro-power technology, according to the company.

Essentially, the system involves water being gravity fed through pipes down a shaft into the turbines, which produce electricity for supply to the grid and also pump the water back to surface. The mine storage system reportedly has a high round-trip efficiency of 75-85% and proven durability.

The MoU, Anglesey says, could lead to numerous future benefits including:

  • A potential long-term revenue stream from the Grängesberg Mine to enhance the cashflow and net present value;
  • Enabling the circular economy with existing technology, turning a depleted mine into a power storage asset ensuring generational benefits; and
  • Partnering with a well credentialled Swedish partner and potential exposure to Scandinavian investors

Jo Battershill, Chief Executive of Anglesey Mining, said: “We are very pleased to have signed this MoU with Mine Storage over our Grängesberg project. The Mine Storage team has identified the Grängesberg Mine as one of the most suitable locations to design, install and operate what could potentially be a significant pumped hydro-storage project.

“As we have stated previously, we believe the Grängesberg project provides substantial strategic value and has the potential to be restarted as one of Europe’s largest individual producers of high-grade iron ore concentrates. We continue to investigate ways to advance the project through to a Financial Investment Decision, which may involve securing a strategic investor, offtake partner, separate listing, or a combination of these options.

“Any potential to convert the mine into a long-term source of hydro-storage power only adds to the strategic value of the asset. We look forward to working with Mine Storage on the options for integrating a pumped hydro-storage solution into the mine plans.”

Thomas Johansson, Co-founder and Chief Executive of Mine Storage International, commented: “This collaboration with Anglesey is a great confirmation of the value Mine Storage can offer not only in the global energy transition, but also for a sustainable mining industry. Anglesey Mining and Grängesberg Iron show a great leadership and we are both pleased and honoured to have entered into this collaboration with them.”

A prefeasibility study from July 2022, which envisaged a restart of Grängesberg in central Sweden, highlighted potential production of 2.3-2.5 Mt/y of iron concentrate grading 70% Fe. This was from a mine able to operate at an average rate of 5.3 Mt/y for 16 years.

Nordic Iron and VB Elnät look to engineer mine power access solution at Blötberget

Nordic Iron Ore has entered an engineering agreement with VB Elnät to determine the required measures for connecting its Blötberget project in Sweden to the electric grid.

In order to re-start mining activity in Blötberget, Nordic Iron Ore needs access to a maximum capacity of 20 MW. The company has previously signed a letter of tntent with Hitachi Energy regarding installation and operations of a permanent 50/10 kV power station, which will supply the mining area with electrical power.

During construction of the mine and the power station, access to temporary power supply will be necessary to make preparatory work such as construction of ramp, lighting, ventilation and drainage of water.

In order for Nordic Iron Ore’s facility to connect to the power grid, VB Elnät must evaluate required measures in its own electric grid and prepare documentation for applications for necessary permits, partly for the temporary usage of electrical power and partly for the permanent connection of the 50/10 kV power station, the company said.

The indicative time plan for this planning is that Nordic Iron Ore will be able to use 1 MW during the autumn of 2023 and gradually increase its usage to a maximum capacity of 20 MW during 2024-2025.

Nordic Iron Ore was formed in 2008 with the main aims of resuming mining operations in Blötberget and Håksberg and conducting exploration of the expansion potential of the Väsman field, together forming the Ludvika Mines, in southern Dalarna.

Volvo CE makes electric wheel loader investment in Arvika plant

As part of its ambition towards industry transformation through sustainable solutions, Volvo Construction Equipment (Volvo CE) has announced an investment into the production of electric wheel loaders from its plant in Arvika, Sweden.

The SEK65 million (circa-$6.3 million) investment from Volvo Group will allow the Arvika factory in Sweden – which specialises in the production of medium and large wheel loaders – to expand its facilities with a new building and allow for the phased introduction of new electric wheel loaders.

It is not only a milestone in the plant’s almost 140-year history, but a significant moment for Volvo CE and its determination to be completely fossil free by 2040, the company said. This is in line with the aims of the Paris Agreement and as laid out in the manufacturer’s industry leading Science-Based Target goals. It is also a step forward in its ambition for 35% of its machines sold to be electric by 2030.

Coming soon after an announcement to invest in electric haulers from the company’s production facility in Braås, Sweden, the announcement shows Volvo CE is committed to achieving more sustainable solutions for customers across all its product lines. These announcements are part of an investment strategy that allows Volvo CE to advance electric solutions across its production facilities, including also the Konz facility in Germany, Belley in France and Changwon in South Korea, where other electric machines are made.

Site Manager, Mikael Liljestrand, says: “This is a clear signal of our commitment to building the world we want to live in. It is more than 40 years since we last invested in a new building and what better reason now than to invest in our future, our planet and the next generation. We know that this is not only important to our customers and stakeholders, who rightly have high expectations on us, but it is also close to our hearts to be part of something bigger in building our future.”

Volvo CE has already introduced compact electric wheel loaders to the global market with the L20 Electric and L25 Electric wheel loaders proving to be efficient, zero-exhaust emission solutions capable of driving down carbon emissions while maintaining high productivity across a variety of customer applications. Together with the ECR25 Electric, ECR18 Electric and EC18 Electric compact excavators and the mid-size EC230 Electric excavator, Volvo CE has one of the largest electric ranges on the market.

Thanks to the investment, Arvika will erect a new building, approximately 1,500 sq m, which will allow the facility to free up areas inside its assembly factory to be able to build electric wheel loaders. While it has not yet been announced which models will begin their electric transformation and exactly when, production of both electric wheel loaders and more traditional wheel loaders fitted with combustion engines will continue for now on the same production line.

Volvo CE will ensure a phased introduction model by model, taking into account all aspects of the electric ecosystem as it does so, including infrastructure requirements, charging solutions, battery handling and business models. The result will be reliable mid-size and larger electric wheel loaders that can easily be integrated into customers’ business, it said.

It is not the first sustainability initiative from the Arvika facility. Despite increasing production last year, the factory managed to reduce its internal climate footprint by 350 t of CO2 thanks to a variety of emission reduction efforts.

“Our goal at the factory in Arvika, as well as Volvo CE and the entire Volvo Group is to be climate-smart and to produce fossil-free machines,” Liljestrand said. “Together, we are quite clear that we want to lead this transformation and be the driving force of more sustainable ways of working for the benefit of our planet. This investment is Arvika’s exciting first step towards electrification.”

Building work is set to begin later this year, with further announcements on when production will begin to come.

Epiroc equipping LKAB Kiruna personnel with new Mobilaris safety solutions

LKAB is further increasing its safety capabilities by implementing several solutions from the Mobilaris Mining Intelligence platform at its Kiruna mine in northern Sweden, Epiroc says.

The platform, now 100% incorporated into Epiroc following the consolidation of its ownership in Mobilaris MCE AB in 2021, allows all employees to receive alarm and crisis information and confirm directly on their mobile phones in an emergency situation, Epiroc says. Employees can also obtain position support and the ability to navigate faster to rescue chambers with the help of applications on their mobile phones.

This means rescue personnel will now have the tools and means to manage emergencies better and faster, according to the OEM.

Joel Kangas, LKAB’s Kiruna Mine Manager, said: “We want to shorten the time from when an alarm goes off to when everyone is safe, and we believe this digital solution can help us with that.”

Hans Wahlquist, Global Director of Product Management at Epiroc, said: “LKAB already has a high level of safety, but now there are new technologies and new opportunities, and they have the infrastructure required for this installation. This project will give everyone in the mine more information about the situation in real time.”

LKAB is setting a new world standard for mining where digitalisation forms an important step towards easier, safer and more efficient work in the mine. The mobile safety solution project is a collaboration between LKAB and Epiroc, involving both existing products from Epiroc and new developments. The project began in the autumn of 2022 and the goal is to start rolling out the solution in the spring of 2023 at the Kiruna mine.

Andreas Ericson, General Manager Epiroc Mining Intelligence, said: “Collaborations with customers are crucial for finding innovative solutions. This project demonstrates the potential for digital transformation in the mining industry, bringing us one step closer to a smarter and more efficient future.”

The following four modules from the Mobilaris Mining Intelligence portfolio are included within the project:

  • Location of people with the ability to receive alarm and crisis messages on their mobile phones through Mobilaris Situational Awareness and Mobilaris Virtual Tag;
  • Distribution of emergency messages and support provision for getting people to safety through Mobilaris Emergency Support;
  • Three dimensional map in vehicles for navigation assistance, increased traffic safety and the ability to quickly find the nearest rescue chamber through Mobilaris Onboard; and
  • Three dimensional map on the employee’s mobile phone for navigation assistance and the ability to quickly find the nearest rescue chamber through Mobilaris PocketMine.
