The flotation of molybdenite seemed to be less influenced by xanthate than by kerosene, while that of chalcopyrite showed the opposite The optimum concentration of sodium sulfide for separation was 003 mol/L, which rejected 83% chalcopyrite and recovered 82% molybdenite in the single mineral flotation.

In reverse flotation, proper reagents induce the pay minerals to become hydrophobic (water repelling) and the waste minerals to become hydrophilic (water attracting) Aeration is added through spargers at the bottom of the flotation cell The bubbles attract and then float the waste minerals, leaving the pay minerals in the underflow.

flotation of the sulphide mineral surface had been achieved at lower dosages than was required with di-C2-DTC and C2-X The superior rate of flotation of the copper minerals with di-C2-DTP may be attributed to the added hydrophobicity provided by the additional alkyl group of di-C2-DTP.
