Swiss Tower Mills to deliver ‘largest, most powerful’ stirred mills in the world to Russian copper project

Swiss Tower Mills Minerals says it has been awarded an order for the delivery of four energy efficient VRM50000-6500 grinding mills for a large greenfield copper project in Russia.

The scope of the project, awarded in the June quarter of 2021, includes the design, manufacturing and delivery of four Vertical Regrind Mills (VRM), each complete with a 6,500 kW variable speed drive package and a user-friendly control system.

Each regrind circuit will process up to 500 t/h of flotation concentrate.

These mills will be by far the largest and most powerful stirred mills in the world, according to Swiss Tower Mills Minerals.

Deliveries will take place during 2022 and 2023.

Last month, Swiss Tower Mills Minerals confirmed the award of an order for the delivery of one VPM10 vertical stirred grinding mill for the Navachab gold mine plant expansion in Namibia.

Polymetal pushes forward with Veduga gold project development

The Board of Polymetal has approved a $447 million investment in the Veduga gold project in the Krasnoyarsk Region of Russia based on the results of a recent prefeasibility study (PFS).

Veduga was discovered in 1977 and extensively explored between 1988 and 1996. Polymetal has been a partial owner of the property since 2006 with the original 50% stake acquired through the joint venture with AngloGold Ashanti. In this time, the mining of oxide ore has started, an initial NI-compliant reserve and resources estimate was prepared and open-pit mining of sulphide ore kicked off.

The latest investment will see Polymetal target 10 years of conventional open-pit mining of five open pits until 2031 (including pre-production stripping in 2022-2024), and 12 years of underground mining using a skip shaft for hauling from 2030 to 2041. First production is expected in the June quarter of 2025. This is based off a 4 Moz reserve base grading 3.9 g/t Au.

The prefeasibility study was based on a 2 Mt/y flotation concentrator with dry stacking of tailings. This would see flotation concentrate processed at the future POX-2, while volumes in excess of the facility’s capacity will be sold to third parties.

Veduga could also potentially become a source of feed for the future Pacific POX project, Polymetal said, adding that flowsheet development has been supported by extensive external and in-house metallurgical testing.

Average life of mine annual production is estimated at 200,000 oz of gold at all-in sustaining costs of $800-850/oz.

The project is expected to materially contribute to Polymetal’s carbon emission reduction targets, relying on hydro power to ensure relatively low emission intensity level of 405 kg CO2e/oz gold equivalent in 2025-2030 on average. This is well below the group’s target of 560 kg CO2e/oz of gold equivalent by 2030, it said.

Of the $447 million capital expenditure (inclusive of capitalised pre-stripping costs), $77 million is dedicated to a “post-launch” skip shaft and underground infrastructure construction in 2027-2029. Polymetal said further studies will be undertaken to evaluate alternative ore transportation options that could reduce the capital spending. It also said it plans to use exclusively battery-electric vehicles throughout the underground mine.

The extended open pit allows to shift underground development capital costs beyond the start-up capital expenditure, Polymetal added.

Polymetal currently owns a 59.4% stake in Veduga and holds a call option to increase its stake to 100% at a pre-determined price giving VTB Bank a fixed rate of return on initial investment. Following the final statutory clearance – expected in the June quarter of 2022 – Polymetal plans to fully consolidate the asset.

MTS, Ericsson deploy Russia’s first commercial 5G-ready private network at Polymetal’s Nezhda

Mobile TeleSystems PJSC, a leading provider of media and digital services, has completed the construction and launch of operations of what it says is Russia’s first commercial 5G-ready Private network at Polymetal International plc’s Nezhdaninskoye gold deposit in the Republic of Sakha (Yakutia).

The planned installation of the network, built on the Ericsson Dedicated Networks solution, was announced last year.

Within the project, MTS deployed a wireless network for Yuzhno-Verkhoyansk Mining Company JSC, affiliated with Polymetal. The network supports integrated mining dispatching systems, positioning, remote and automated control of various equipment, including excavators, drilling rigs, measuring devices, monitoring systems for remote equipment and video monitoring.

Within the project a full range of turnkey works and services has been implemented, including site inspection, network architecture design, supply and installation of radio base stations, network core and auxiliary equipment, network testing and commercial launch, MTS says. At the first stage, the network built on Ericsson solutions will operate in the LTE standard with the possibility of smooth and fast upgrade to 5G, according to the company.

The network is built on Ericsson Dedicated Networks solution, which complies with the 3GPP standards and includes a full-fledged carrier-grade network core. It supports 4G and 5G Non-Standalone (NSA) simultaneously and allows dual-mode core capability to support 5G New Radio Standalone (5G NR SA). An enterprise can use all the carrier grade packet network functions for its own mission-critical applications, MTS says.

Georgy Dzhabiev, Director, Digital Solutions, MTS, says: “We are grateful to our partner Polymetal for cooperation that resulted in the creation of the first commercial Private LTE network in Russia for remote monitoring and managing critical processes in difficult geographic and weather conditions. I am sure that the competence and experience of MTS in the implementation of unique network and IT solutions, digitalisation and automation of production processes will help our customers to increase their business efficiency and improve the working conditions.”

Alexander Laguta, Head of Information Technology and Communications department, Yakutsk branch of Polymetal, says: “The system is already showing its effectiveness and is ready to move to next stage of introducing innovative technologies in production. The Private 5G-ready network will significantly increase the speed of transferring large amounts of data and reduce the cost of maintaining the technological network. One of the first projects on the basis of this network will be launch of dispatching systems, remote control of drilling rigs and video monitoring.”

Alexander Romanov, Head of Private Networks, Ericsson Russia, says: “The Private Network is the backbone of critical communications infrastructure and the Industrial Internet of Things, not only in mining, but also in other industries with a high demand for seamless coverage, performance, security and reliability while supporting mission-critical business processes in a new digital reality.”

At the next stages of the project, the implementation of a dispatch radio communication system based on MC-PTT (Mission Critical Push-to-Talk) over LTE network is planned, along with integration with the internal telephone network of the enterprise.

HALMEK LITHIUM to work with Metso Outotec on lithium hydroxide plant

HALMEK LITHIUM has selected Metso Outotec’s patented lithium hydroxide process for production of battery-grade lithium hydroxide at its greenfield plant in the Tula region in Russia.

The order value, which is not disclosed, has been booked in the company’s Metals June quarter orders received.

Metso Outotec’s scope of delivery consists of the engineering and key equipment supply for the lithium hydroxide process, the basis of which will be the Metso Outotec OKTOP® autoclave plant. The environmentally sound production process is one of Metso Outotec’s more than 100 Planet Positive products, the company said.

Pavel Galchenko, VP, Halmek Lithium, said: “One of the most important tasks in the project was the selection of technology. Instead of the more traditional sulphuric acid processing to produce lithium hydroxide, we decided to choose the Metso Outotec lithium hydroxide process as it is the most promising and environmentally-sound process at the moment.

“The pilot tests conducted at the Metso Outotec Research Center in Pori, Finland, provided excellent results.”

Mikko Rantaharju, Vice President, Hydrometallurgy business line at Metso Outotec, said: “Metso Outotec has developed lithium hard rock-related technologies for some 20 years now. It started with the battery-grade lithium carbonate process and, when the market changed to favour lithium hydroxide, the process flowsheet was converted to directly produce battery-grade lithium hydroxide monohydrate from spodumene.

“Both of the processes are patented and will be significant assets in our battery chemicals business, meeting the need to produce high-end lithium-ion battery chemistries for the growing market.”

HALMEK LITHIUM’s new hydrometallurgical plant, which will complement its existing lithium hydroxide plant, is currently under construction. As raw material, the new plant will use spodumene concentrate; it will feature a capacity of 20,000 t/y of battery-grade lithium hydroxide monohydrate, which is used in the production of batteries for electric vehicles. The first production line is planned to start up in 2023, and the second production line with a capacity of 20,000 t/y is expected to start production in 2026.

ALROSA looks to ABEL HM pumps for filter press feeding

Piston diaphragm pumps from ABEL are helping Russia’s ALROSA with its filtration process at one of its diamond mines in the country.

In Spring 2021, ABEL received an order for the delivery of six of these piston diaphragm pumps, HM pumps, following an initial HM pump order in 2020. This inaugural pump was delivered to ALROSA in February 2020 as replacement for a centrifugal pump previously used for filter press feeding. At the beginning of August, the ABEL pump was commissioned at the diamond producer’s plant. The dewatering result (higher solids content, shorter filtration time) was so convincing that ALROSA decided to feed all filter presses in this plant with the pumps, ABEL said.

The latest delivery is being facilitated by ABEL’s official distributor in Russia, SibComplectService.

ABEL’s HM pumps are available as single- or double-acting versions. They come with a high flow rate, reliable function and particularly low operating and maintenance costs, the company says.

In addition to filter press feeding, the hydraulic diaphragm pumps are also used for sludge transport, spray dryer feeding, rotary kiln feeding, autoclave feeding, and sealing/rinsing water supply, among other applications.

Petropavlovsk gears up for refractory gold push with Pioneer plant launch

Petropavlovsk has announced the “technical launch” of the flotation plant at its Pioneer operations in Russia’s Far East, becoming the second facility in the gold miner’s portfolio able to process refractory gold ore and produce flotation concentrate.

Denis Alexandrov, CEO of Petropavlovsk, said: “The successful launch of the Pioneer flotation plant represents a key strategic milestone for the company. We are pleased to have commissioned the facility slightly ahead of the mid-year target we set when I joined the company last year.

“The new plant will enable Petropavlovsk to take full advantage of Pioneer’s substantial refractory ore reserves while providing an additional source of own-mined concentrate for our state-of-the-art Pressure Oxidation (POX) Hub.”

The new Pioneer flotation plant has the capacity to process 3.6 Mt/y of refractory gold ore. Once fully operational, the plant is expected to deliver more than 100,000 t/y of refractory gold concentrate for treatment at its POX Hub, the company says.

The opening of the Pioneer flotation plant doubles the group’s capacity to process refractory gold ore which, including the existing Malomir flotation plant, now stands at 7.2 Mt/y. Pioneer is expected to become fully operational by July and to produce around 60,000 t of concentrate in 2021.

Petropavlovsk said the construction of a third line at the Malomir flotation plant remains on track, and will add an additional 1.8 Mt/y of flotation capacity from the September quarter of 2022, bringing the total combined group capacity to 9 Mt/y.

“The launch of Pioneer flotation and expansion at Malomir will reduce the reliance of the POX Hub on treating lower-margin third-party concentrates,” the company added.
