  Flotation of Nickel-Copper Sulphide Ore: Optimisation of …

  201667 · The Taguchi method was therefore, selected to determine the optimum conditions for maximising 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.
