Metso Outotec supports GTK Mintec’s pilot plant plans with new flotation cells

Metso Outotec is set to deliver new, smart flotation cells to GTK Mintec’s pilot plant in Outokumpu, Finland, as part of the survey’s modernisation and expansion program.

The delivery consists of around 20 pilot flotation machines and additional equipment, with GTK Mintec replacing existing flotation cells at its pilot plant.

The new flotation cells will support the improvement of the monitoring of beneficiation studies and process design, according to Metso Outotec.

“GTK and Metso Outotec promote sustainable and competitive mining technologies,” Stephan Kirsch, President of Metso Outotec’s Minerals business area, says. “We are pleased that GTK chose Metso Outotec’s leading-edge flotation technology for their test facilities.”

Jouko Nieminen, Head of the Circular Economy Solutions unit for the Geological Survey of Finland (GTK), said: “The test plant and laboratory in Outokumpu offer mining customers a comprehensive service package. The whole production process needed for a mineral deposit can be tested there on the scale required by the research problem.

“Through the flotation investment, our domestic and international customers can use state-of-the-art technology in research related to battery minerals and circular economy materials, for example.”

Outotec bolsters flotation line with new cells, control solutions

Outotec says it has expanded its offering with new flotation cell and level-control solutions for “superior metallurgical performance”.

The new solutions from the mineral processing equipment manufacturer includes the Outotec TankCell s-Series flotation units – standardised units based on the company’s proven TankCell e-Series solution – and Outotec CellStation (pictured), an “intelligent and easy-to-operate solution” for controlling the air feed and pulp level in flotation cells, it said.

Outotec TankCell s-Series flotation units are “easy to operate, allow a flexible layout, and are designed to enable gains in throughput, grade, and recovery, while improving the sustainability and minimising the environmental impact of your process”, it said.

The units are built with cost-effective standardised equipment delivered preconfigured to optimise delivery lead time and capital expenditure, the company added.

“Based on in-depth test work, we can design a tailor-made flotation circuit based on the s-Series that will deliver optimised cell volume and residence time for your plant,” Outotec said, adding that units are available in sizes from 5 cu.m to 30 cu.m.

Outotec CellStation, meanwhile, is an intelligent solution that simplifies the “often-complex task of controlling the air feed and pulp levels in flotation cells”, Outotec said. This is a task that becomes more challenging as the number and complexity of cells increases, it added.

The solution incorporates Outotec’s ExactLevel controller, which enables more accurate level control and significantly reduces process disturbance, resulting in more stable froth conditions and therefore improvements in the flotation cell’s metallurgical performance, it said.

CellStation has plug-and-play connectivity with the Outotec FrothSense sensor system, which measures the essential properties of froth, including speed, direction, bubble size, stability, and colour, and provides statistical data related to these variables.
