What We Do

Cosmic Boy

The high-grade nickel ore mined from Forrestania is processed through the Cosmic Boy Concentrator (CBC) and sold into offtake agreements with Jinchuan Group, China’s largest stainless steel producer and BHP Ni West.

The CBC treats the raw nickel and produces a consistent nickel concentrate product grading approximately 14% nickel. The concentrate produced from the Forrestania project is characterised by low impurities such as magnesium which makes it more desirable to smelters.

The concentrator consists of a three-stage crushing circuit, followed by a single closed-circuit ball mill and a system of flotation tanks and thickening/filtration system.

The recovery rates for Cosmic Boy currently average between 85% and 90%. The recovery rates refer to the percentage amount of nickel recovered from the raw ore during processing.

At CBC a Mill Recovery Enhancement Project (MREP) has recently been commissioned.  The MREP incorporates the use of the Company’s BioHeap™ technology to recover nickel from the tailings waste stream. The nickel recovered is then converted into a high-grade nickel sulphide product which can either be mixed with the CBC floatation concentrate or sold as a separate premium product suitable to be processed in a refinery.
