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.

First Ore Mining and Metso Outotec strike thickening plant deal for Pavlovskoye

The First Ore Mining Company (FOMC), part of ARMZ Uranium Holding Co, says it has signed a cooperation agreement with Metso Outotec “underlining the parties’ interest in continuing their strategic partnership in the design, supply, installation, control and commissioning of the thickening plant for the Pavlovskoye field”.

The agreement waas signed by Igor Semenov (right), Executive Director, FOMC JSC, and Markku Teräsvasara (left), Vice President, Metso Outotec.

The Pavlovskoye polymetallic deposit on the Novaya Zemlya archipelago is the largest such deposit in Russia with 47.7 Mt of ore reserves (2.49 Mt f zinc, 549,000 t of lead and 1,194 t of silver), according to First Ore Mining.

The cooperation with Finland’s Outotec (since merged with Metso to make Metso Outotec) emerged more than a year ago on the sidelines of the St. Petersburg International Economic Forum, which gave rise to an initial pact. Since that time, the company’s experts, together with Aker Arctic Technology, have elaborated a detailed draft design for the floating concentrator and set out a preliminary thickening flow chart and main equipment layout, First Ore Mining said.

In September, representatives from Metso Outotec visited the Pavlovskoye field. In the course of the field activities, the company examined the site for the planned thickening plant, tailings pond and infrastructure facilities, First Ore Mining said. It also acknowledged the ore samples were representative and could be used in testing.

The next stage within the partnership will include tests to be carried out at Metso Outotec Research Center in Pori, Finland. Once the work is completed and the final thickening flow chart is developed, Metso Outotec will present the guaranteed performance indicators and design values to ensure the plant’s productivity and the high quality of the concentrates and metal extraction for the ore types studied, FOMC said.

Semenov said: “I am confident that working together with Metso Outotec will significantly improve the thickening indicators for Pavlovskoye ores, which were obtained during the studies in the previous years. As a result, we will produce premium concentrates that are in demand in the global lead and zinc markets.”

Teräsvasara added: “Indeed, it is quite interesting to participate in the development of this unique project for processing minerals in the Russian Arctic. In addition to standard technological and economic matters, harsh weather conditions, lack of infrastructure, and high requirements to environmental safety in the vulnerable Arctic wildlife have made us search for the best available technologies to cover all these points.”

The Pavlovskoye project includes plans to build the northern-most mining and processing plant to produce lead and zinc concentrates, with First Ore Mining as the project operator.

Outotec celebrates 70 years of technology innovation at Pori ORC

Outotec is, this week, celebrating 70 years of sustainable technology development at its Outotec Research Centre (ORC) in Pori, Finland.

The ORC in Pori is unique in the industry, according to the company, with its expertise in the minerals and metals processing value chain ranging from ores to finished metals and recycling.

The centre was established in 1949 and, since then, has been a part of the company’s long-term research and development strategy. The company is holding a two-day seminar to celebrate 70 years of process development on October 15–16, with speakers including leading researchers, professors and industrial influencers.

One of several cutting-edge technologies developed at the ORC is Outotec Flash Smelting, which is still one of the world’s most commonly used processes to produce primary copper and nickel. This innovation was developed at the ORC at the end of 1940s.

The centre’s laboratories conduct tests on raw materials for Outotec’s customers and the related production processes. Current testing capabilities include nine laboratories and pilot plants, with, annually, some 200 research projects conducted, and more than 250,000 samples analysed.

Outotec said: “There is a genuine need for continuous development of processes since ore deposits are becoming leaner in grade and more difficult to utilise. The conventional methods are often insufficient to make them financially viable. Outotec’s research centre in Pori supports customers in selecting and, if necessary, developing new solutions for the efficient and environmentally sustainable extraction of valuable minerals from raw materials.”

The company said it can take decades for a completely new technology to establish itself in the market, but once the technology platform is developed, new applications may quickly be found. This has happened to cobalt and lithium processing technologies in recent years with the electrification of transport, it said.

Jarkko Partinen, Vice President, Technology and R&D at the ORC, said the cobalt extraction technology developed in Pori back in the 1960s is, today, gaining in importance due to the advent of electric transport.

“Thanks to our continuous research and development work, we are able to offer customers new and efficient ways of processing materials such as battery chemicals,” he added.

Kalle Härkki, Head of Outotec’s Metals, Energy & Water business area, said Outotec’s customers each face unique challenges and it is the company’s job to create solutions that help them succeed.

“We are proud of our process and technology expertise, and having our own research centre is a competitive strength,” he said. “ORC has been characterised by research into environmental protection, the circular economy, and resource efficiency before any of these topics became mainstream. One of the earliest studies, which dates back to 1951 and would nowadays be linked to the circular economy, examined useful applications for sulphur gas roasting residues.”

ORC employs 180 research and development professionals, 45 of which are process and technology development engineers, half of whom hold a doctorate level degree. There is a dedicated group working in modelling and digitalising process expertise.

The laboratories employ more than 100 professionals most of them working in three shifts specialised in building and maintaining test rigs and equipment, conducting the test work planned by the process development engineers, and analysing samples taken from the tests.

In 2018, the ORC welcomed more than 1,300 visitors, the vast majority of which were customers, researchers and people attending training.
