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.
