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.

Metso Outotec books zinc plant order as it agrees sale of aluminium business

Metso Outotec has signed a contract to deliver a complete package of key process equipment for a greenfield zinc plant in the Chelyabinsk region in Russia.

The contract value of approximately €100 million ($122 million) has been booked in Metso Outotec’s Decemeber quarter order intake, a quarter of which will be booked in Minerals segment and the rest in Metals segment.

The order for the Verkhny Ufaley plant includes an equipment package for zinc concentrate processing, iron precipitation, solution purification and electrowinning (EW) technologies for safe and sustainable zinc processing based on OKTOP® reactor and plant products.

The order also contains a circuit heat recovery system, zinc EW and ingot casting equipment, as well as high-efficiency cooling towers for zinc EW and gypsum removal with drastically reduced emissions compared with conventionally-designed cooling towers, the company said. Clarifying solutions for consistent solid-liquid separation, high-performance Larox® FP and RB filters with low energy consumption, as well as fully integrated digital process automation for more reliable and flexible operation are also part of the order.

“Metso Outotec has been supplying minerals processing and metals refining technologies to our customers in Russia for a long time,” Jari Ålgars, President, Metals business area at Metso Outotec, said. “The new zinc plant will utilise Metso Outotec’s proprietary technology, which is both sustainable and highly cost effective.”

Stephan Kirsch, President of the Minerals business area at Metso Outotec, added: “Metso Outotec provides leading-edge technology for extensive zinc processing plants. This includes proprietary process equipment and know-how from raw material to final zinc product and various by-products.”

The technology to be delivered is the most cost-efficient technology available for zinc raw material processing, enabling efficient zinc and by-product recovery from a wide range of primary zinc raw material, according to Metso Outotec.

In a separate press release, Metso Outotec announced it had agreed to sell its Aluminium business to REEL International, headquartered in France. The business was put up for sale a year ago and has since been reported under the company’s discontinued operations.

The business to be divested comprises of green anode plants, anode rodshops, and casthouses used in aluminium smelters as well as related equipment and services. Approximately 120 Metso Outotec employees will join REEL upon closing, which is expected to take place during the March quarter of 2021, Metso Outotec said.

The parties have agreed not to disclose the value of the transaction.

Outotec mineral process equipment destined for Okvau gold project

Outotec says it has been awarded a contract from Renaissance Minerals, a subsidiary of Emerald Resources, for the delivery of process equipment to the greenfield Okvau gold project, in Cambodia.

The order value, booked into Outotec’s 2020 March quarter order intake, is around €13 million ($14.2 million).

Outotec’s scope includes the delivery of an Outotec HIGmill® high intensity grinding mill, a semi-autogenous (SAG) mill, TankCell® flotation cells, an OKTOP® Conditioner, thickeners and spare parts.

The Okvau gold project is in the Mondulkiri province of eastern Cambodia. The 2 Mt/y operation will be the first large-scale mining project in the country, according to Outotec, with project commissioning expected in the June quarter of 2021.

Last year, ASX-listed mining contractor, MACA, entered into a memorandum of understanding with a subsidiary of Emerald Resources to supply equipment and contract mining services at the project.

Paul Sohlberg, Head of Outotec’s Minerals Processing business, said: “We are pleased to be part of Cambodia’s first significant gold processing project with Emerald’s highly credentialed gold project development team.

“Outotec’s leading technologies such as energy efficient ultrafine grinding, proven flotation technology for low grade sulphide ore and superior thickening technology, enable our customer to do profitable business sustainably. This order will strengthen Outotec’s position as a supplier of advanced minerals processing technologies in Southeast Asia.”
