Lime use and functionality in sulphide mineral flotation: A review

Silver Queen mine (Canada) a combined limestarchSO 2 conditioning scheme is used for copper flotation from the Pb/Zn sulphides (Bulatovic, 2007b). In the process, lime (1200 g/t) and starch (200 g/t) are used first, at pH –, after which the pH is reduced to with SO 2 (200 g/t) and the copper sulphide floated.

EFFECT OF GRINDING CHEMISTRY ON THE SULPHIDISATION AND FLOTATION

The results show that the grinding chemistry drives the flotation performances of the ore at each oxidation stage, however strong ore oxidation presents a lower difference in pulp chemistry and similar flotation response for all grinding media tested. For the oxide ore, the system of sulphidisation and flotation are more complex with little to no references in the literature about

[PDF] Effect of grinding media on the flotation of copper

to avoid the shortage of floatability and nonpurpose flotation in marmatite flotation is a big problem. This paper innovatively studies how to reduce these two negative phenomena from the perspective of grinding media. The effects of steel and stainlesssteel balls on the flotation performance of copperactivated marmatite were investigated mainly through

EFFECT OF AUTOGENOUS AND BALL MILL GRINDING ON SULFIDE FLOTATION.

At the same meshofgrind copper, nickel, and cobalt recoveries were higher and residual sulfur in the tailings was lower with autogeneously ground pulps. With ballmill ground pulps the residual sulfur could not be lowered even at increased levels of collector addition. An electrochemical interaction between grinding media and sulfide minerals is thought to have a greater effect on
