The Cosmic Boy Concentrator treats raw nickel bearing ore from the Forrestania project to produce a consistent nickel concentrate product, grading approximately 14% nickel. Concentrate produced from the Forrestania project is characterised by low impurities such as magnesium which makes it more desirable to smelters. Current capacity allows for the treatment of 600,000 tonnes per annum of ore, with the potential to expand to 1,000,000 tonnes per annum.
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.
Recovery rates for Cosmic Boy currently average between 90% and 93%. Recovery rates refer to the percentage amount of nickel recovered from the raw ore during processing. Rates achieved by Cosmic Boy are considered good by industry standards.
