Challenges in processing nickel laterite ores by flotation
It s a shame that the highly depressed nickel market led to the cancellation of MEI s October Nickel and Cobalt Processing conference as there are enormous challenges in the processing of nickel ores particularly the laterites. The majority of the world s nickel resources occur as laterite ores which are complex low grade and expensive to treat using conventional smelting and high

Flotation of Nickel-Copper Sulphide Ore Optimisation of
the flotation recovery of Ni Cu and Co from a nickel-copper sulphide ore. The effect on flotation performance of various parameters such as pH collector dosage solids and depressant dosage at different levels was investigated. Therefore the main objective of the study was to optimize the process parameters for the flotation of base metals
