flotation using flocculants for copper sulphide ore
Principles and practice of sulphide mineral flotation
Synopsis. This paper presents both the fundamentals of sulphide mineral flotation and the practical aspects of sulphide ore flotation. The fundamental aspects of the flotation of sulphide minerals both in the absence and presence of thiol collectors are discussed in relation to their crystal structure surface chemistry and electrochemical characteristics.

CHAPTER 7 FLOTATION OF SULPHIDE MINERALS
sulphide ore the galena can be floated first at higher using cyanide to prevent sphalerite and pyrite from floating. Then activation of sphalerite with copper sulphate and high pH to depress pyrite enables a sphalerite concentrate to be made. Finally a lowering of pH can enable a pyrite concentrate to be made if required.

Flotation of mixed copper oxide and sulphide
Abstract Sherwood Copper s Minto Mine processes a high grade copper–gold deposit in Yukon Canada. The ore mined is from a primary copper sulphide deposit with separate additional deposits of copper oxides. In conjunction with Ausmelt Chemicals Minto is currently investigating options to recover copper oxide and sulphide minerals using flotation by blending their primary sulphide ore with

The effects of polyacrylamide flocculants on sulphide
The effect of polyacrylamide on flotation of a copper-molybdenum ore was investigated in a series of batch flotation tests. Flocculant concentrations up to 10 parts per million did not lower either concentrate grade or recovery. The presence of an oil phase from the liquid flocculant also had no noticeable effect on flotation.

INVESTIGATING THE POTENTIAL OF Eriez Flotation
A number of tests were conducted on variety of copper sulphide ore samples. Fresh feed samples were ground in a rod mill to coarse size distributions while plant samples were only screened to remove excessively coarse material. For each set of tests a conventional rougher flotation test was conducted using a Denver laboratory flotation cell.
