LKAB, Mitsui on board with Talga’s graphite anode journey in northern Sweden

Talga Resources, Mitsui and LKAB have signed a Letter of Intent (LoI) that could see the three jointly develop the Vittangi Anode project, in northern Sweden.

The LoI is a non-binding agreement between the parties whereby, after completing the detailed feasibility study on the project, expected March 2021, and due diligence, LKAB, Talga and Mitsui intend to negotiate a business agreement including ownership and investments in the project.

Talga is the 100% owner of the Vittangi graphite project and proprietary technology for anode battery production. Permit applications for the graphite mine were filed in May 2020.

The ASX-listed company is intent on establishing a European supply of sustainable, low-CO2 emission anode materials for lithium-ion batteries, using its 100% owned Swedish mineral assets and battery material technologies.

Building on the company’s vertically integrated business strategy, the development plan includes construction of a scalable lithium-ion battery anode production facility and integrated graphite mining operations in northern Sweden, with initial production capacity of 19,000 t/y coated anode from an annual ore mining rate of 100,000 t.

LKAB said growth within the industrial minerals market is a strategic activity for the company to reduce its dependence on the iron ore market, which today accounts for around 90% of external sales.

“There is also a clear sustainability-based rationale, coupled with the growth ambition, to recycle and upgrade by-products and waste streams,” the miner said. “Additionally, the growth will be accelerated through selected acquisitions and investments that offer synergies with LKAB’s market, operations and sustainability ambitions.”

Talga, with its proximity to LKAB’s existing mining operations in northern Sweden, may offer synergies with resources, skills and infrastructure, according to LKAB. “There are also potential commercial synergies with sales and distribution, including the developments in the ReeMAP project that will produce both phosphorus and rare earth elements through recycling mine waste.”

LKAB plots path for fossil-free industrial mine waste recycling park

LKAB says it is planning a fossil-free industrial park for recycling mine waste and producing critical raw materials.

In the ReeMAP project, of which the aim is to develop technology for recycling mine waste, LKAB also plans to produce input materials, including hydrogen, and to electrify processes and, thereby, virtually eliminate carbon dioxide emissions in mine-waste recycling.

Ibrahim Baylan, Sweden’s Minister for Business, Industry and Innovation, comments: “LKAB continues to develop Sweden’s strengths as an innovative nation. ReeMAP is an important initiative to utilise today’s mine waste, leading to increased circularity and contributing to the green transition with both phosphorus and rare earth elements.”

ReeMAP will apply fossil-free processes for recycling mine waste (tailings) from LKAB’s iron ore production and upgrade it to phosphorus products and rare earth elements; products which, owing to import dependency and their economic importance, are classed by the EU as critical raw materials. In addition, gypsum and fluorine products will also be produced at the industrial park, through the hydro chemical processes.

As part of the ReeMAP project, LKAB has already started producing apatite concentrate from mine waste in a pilot plant.

A “pre-study” for the park is to be completed in 2021, with full production, following environmental permitting and construction, estimated to be achievable by 2027.

The planned recycling of mine waste will entail a circular business model and improve resource utilisation, since all valuable minerals will be extracted, according to LKAB. Residual mine waste will continue to be landfilled.

“Thanks to electrification, the process will be almost entirely free of carbon dioxide emissions,” the company said. “Certain minor emissions may arise, due to the release of chemically-bound carbon in apatite (bound in remnants of calcite mineralisation).”

Production of mineral fertiliser will result in a reduction of 700,000 t of carbon dioxide emissions (corresponding to 1% of Sweden’s emissions in 2019), as compared with the alternative of increasing production of mineral fertiliser using conventional technology, it said.

Leif Boström, Senior Vice President for LKAB’s Business Area Special Products, said the investment in the fossil-free industrial park amounted to several billion Swedish kronor.

“The industrial park will be a centre for chemical engineering where innovative technology is used to recover valuable resources,” he said. “Here, we will set a global standard for clean products, energy efficiency and emissions.”

LKAB said: “In agriculture, high crop yields are made possible by the addition of plant nutrients in the form of phosphate fertiliser. As much as half of all agricultural production is dependent on fertilisers. The purity of the product is also important. For example, the phosphate fertiliser LKAB plans to produce will be free of cadmium, a hazardous substance which is contained in some of the material imported into the EU. Rare earth elements are used in many high-tech products, for example, permanent magnets for electric vehicles and wind turbines.”

ReeMAP’s Project Manager, Ulrika Håkansson, explains that several challenges related to technological development, localisation and industrialisation must be addressed.

“We will need up to 50 ha to accommodate our facilities,” Håkansson said. “A railway line and port access are also important, since we plan to ship as much as a million tonnes of product a year. Production, especially hydrogen production, will be energy intensive. We are now looking at all of these requirements and conditions for possible localisation in Luleå, Skellefteå and Helsingborg.”

Jan Moström, President and CEO for LKAB, explains the importance of ReeMAP for LKAB’s strategy and future: “We have an ambition to be one of the most innovative, resource-efficient and responsible mining companies in the world. Through our development projects SUM, HYBRIT and now ReeMAP, we have assumed a global leadership role for industrial transformation and to provide the world with tomorrow’s resources.”

The European Union is tomorrow launching the European Raw Materials Alliance with LKAB as a partner. The aim is to increase the union’s degree of self-sufficiency in critical raw materials. Initially, the alliance will focus on rare earth elements.

Via ReeMAP, LKAB will have potential to produce 30% of the current EU requirement for these materials, it says.

LKAB invests in phosphorus and rare earth production pilot in Sweden

Sweden-based miner LKAB says it will invest SEK45 million ($4.8 million) in pilot plants that could see phosphorus and rare earth metals produced from its own mine waste.

These plants are part of a prefeasibility study to define a commercial mine waste recycling process, ReeMAP, LKAB President and Group CEO Jan Moström said.

The company has made this decision after laboratory tests during 2018 confirmed it could produce more phosphorus and rare earth metals than previously estimated.

From LKAB’s iron ore production, a residual product resembling sand is currently placed in tailings dams. In the ReeMAP project, LKAB intends to recover the residual product and extract rare earth metals (REE) and monoammonium phosphate (MAP) from it.

Recovery and upgrading to phosphorus and rare earth metals is enabled by a patented process that has been developed by the Swedish company EasyMining, which is a Ragn-Sells innovation company within the Ragn-Sells Group. EasyMining is a partner in the ReeMAP project. The core process is based on EasyMining’s CleanMAP technology, which separates phosphate from water through ion sorption instead of energy demanding evaporation. At the same time, it removes impurities such as cadmium, uranium, fluorine in the MAP.

Leif Boström, Senior Vice President, Special Products Division, LKAB, said: “We are going to build two pilot plants for development and preparation for full-scale industrialisation: one in the orefields and one in Uppsala.”

The orefields plant will produce apatite from tailings sand, while the plant in Uppsala will be run by EasyMining, according to Boström.

Full-scale industrial production of MAP will correspond to an estimated 500% of Swedish demand and production of REE will amount to about 2% world production, according to LKAB. The pilot phase will continue through 2020, with a decision to go ahead with full-scale production possibly taken in 2021.

A pilot plant and a part of the full-scale production facilities will be situated close to LKAB’s existing plant´s in northern Sweden. Subsequent processing will take place in another location, for which three main alternatives are now being assessed, according to the company. The three main alternatives are Luleå, Helsingborg and Skellefteå.

Moström: “ReeMAP is a very good example of circular economy, of recovering and reintroducing resources. We will focus on developing an operation in the location that is the best alternative from an environmental point of view, minimises transportation of materials and utilises resources in the best way.

“If we succeed with the industrialisation process, we will create a whole new industry in Sweden that will supply the agriculture and engineering sectors with critical raw materials while at the same time generating jobs and value for society.”
