nickel ore processing manual milling and classification

Application of three xanthates collectors on the recovery

One of the challenges encountered when processing nickel ore is the presence of other minerals like chalcopyrite, pyrrhotite, pyrite and amphiboles in mineral dressing. Hence, there is need to investigate the selectivity of some collectors at optimum flotation parameters (particle size, milling time, pH and flotation cell) to maximize nickel Get price

Cut

In the case of multiple processing options, cut-off grade is used to determine which process or destination the ore will be sent to, by using the following equation: Where U1 is the utility of sending ore to process 1, and U2 is the utility of sending ore to process 2. Utility is defined as the value (economic or otherwise) of selecting a process. Get price
