The underlying mechanism causing hy drophobicity, although obscure, is attributed.
Leaching of the chalcopyrite ore had little effect on its floatability, as indicated by rougher flotation testing. The maximum flotation recoveries, RMAX, were 90 and 88 for the ore and leached.Flotation were determined to achieve the maximum grade and recovery of chalcopyrite and the effect of activated pyrite on the chalcopyrite flotation efficiency was investigated. 2. Materials and methods The experiments were performed on copper ore obtained from Sarcheshmeh Copper mine, Kerman, Iran.

The main useful mineral in the ore is chalcopyrite and the main gangue minerals are talc and serpentine. To eliminate the adverse effect of talc on flotation of chalcopyrite, a frother MIBC was added to remove a talc slime before flotation of chalcopyrite. However, some copper minerals also float into the talc slime.
