Metso has introduced modular Magnetic Separation Plant Units designed to streamline the flowsheet selection process, boost recoveries and simplify operation.

Alex Lagerstedt, Vice President, Plant Solutions at Metso, said: “As the industry leader in mining process technology and modularity, we are excited to launch the Magnetic Separation Plant Units. Besides easy installation and maintenance, the scalable units have been designed to provide unrivaled selectivity, resulting in high recovery of fine and ultrafine particles.”

Compared with a traditional delivery, the modular plant units result in the earliest time-to-volume, according to Metso. Thanks to maximised pre-fabrication in a controlled workshop environment and minimised site work, installation is safer, faster and of better quality.

The Magnetic Separation Plant Units feature a flexible scope to meet the needs of the end customer or EPCM. Delivery includes proven technology for the entire magnetic separation circuit with in-house testing for equipment sizing and flowsheet design, and it can also include automation, installation and commissioning advisory, training, maintenance and service.

Metso’s advanced magnetic separation equipment portfolio consists of SLon® Vertically Pulsating High Gradient Magnetic Separators, Metso High Gradient Magnetic Separators, and/or dry and wet Low Intensity Magnetic Separators. Additionally, the plant units can be equipped with OKTOP® feed tanks, slurry pumps, hoses and valves, and coupled with process control systems and various ancillary products and sampling systems.

Peter Jansson, Product Manager, Magnetic & Physical Separation at Metso, said: “Metso’s High Gradient Magnetic Separator portfolio features a wide range of processing options for many particle sizes and applications, ranging from iron ore concentrates, rare earth ores, battery and industrial minerals to tailings recovery. Combining these magnetic separators into plant units results in flexible and efficient flowsheets.”

For the Magnetic Separation Plant Units, Metso says it can also provide an integrated service offering through its global network. The scope ranges from maintenance, modernisations & retrofits, process optimisation to spares and wears, training and Life Cycle Services.

The Magnetic Separation Plant Units are Metso’s sixth complete plant unit launch for concentrator plants. The previous launches include Stirred Mill and Horizontal Mill Plant Units, Flotation, Thickening and Filtration Plant Units.

Blackstone Minerals Ltd has announced the inclusion of Metso as the technology supplier for the definitive feasibility study of the company’s pCAM (precursor cathode active material) processing plant in its Ta Khoa refinery in Vietnam.

Metso is already involved in the design of the pCAM plant and will also conduct independent pCAM test work to validate the nickel and cobalt sulphates generated during the pilot program for suitability in pCAM generation, the OEM says.

Metso is currently designing the pCAM plant with Wood, providing experience and engineering technical support.

Scott Williamson, Managing Director at Blackstone Minerals Ltd, said: “Blackstone intends to leverage off Metso’s engineering services and know-how into the pCAM facility design, thus de-risking the project and confirming Blackstone’s intent to be a real player in the pCAM space. Securing another world leader to the Ta Khoa project is yet another jigsaw piece in the battery value chain puzzle. Blackstone continues to look forward to project success as it marches towards developing the greenest and most resilient nickel business in the world.”

Blackstone highlighted the OEM’s high value technology in the context of the pCAM facility design, such as the modular OKTOP® reactors (with industrial references for scaling-up pCAM precipitation processes), Larox® filtration technologies and Courier® HX continuous product quality analyser equipment to enable precision control and real-time optimisation.

“Metso has shown that precursors precipitated with OKTOP reactor technology are proven to meet the required chemical and physical properties for high-performance cathode active material,” it said.

Rudi Rautenbach, Director, Minerals Sales, Asia-Pacific, Metso, said: “We are confident that our experience in nickel processing and battery metals technologies will contribute positively to the project. Many of our offerings that are planned to be used in this project are selected from our range of Planet Positive products, which are demonstrably more energy or water efficient than the industry benchmark or Metso’s previous generation products in the market, to help our customers cut their CO2 emissions and/or to achieve other sustainability priorities. We believe these are all in line with Blackstone’s objectives towards developing the greenest and most resilient nickel business in the world.”

Metso says it provides sustainable technology and equipment for the entire lithium, nickel, and cobalt production chain from the mine to battery materials and black mass recycling with project scopes ranging from equipment packages to plant deliveries. Metso has its own pCAM testing facilities.

A February 2022 prefeasibility study on the 90%-owned Ta Khoa project outlined first concentrate production in in 2025, ramping up to nameplate design of 8 Mt/y in 2027. It expected a steady-state average annual nickel output (recovered in concentrate) of circa-18,000 t/y and steady-state average annual concentrate production of circa-225,000 t/y. The project also came with a steady-state refining capacity of 400,000 t/y, with first production of NCM811 precursor material commencing in early 2025.

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.
