galena flotation flow

Chapter 2. Background - UPSpace

Galena and chalcopyrite have been traditionally floated first in the lead circuit after depression of sphalerite and pyrite with sodium cyanide (NaCN). This is followed by the activation of sphalerite with copper sulphate (CuSO4) and its flotation in the zinc circuit, while pyrite is depressed at high pH with lime. The metallurgical performance

Froth flotation - Wikipedia

Principle of operation. For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral surfaces are naturally hydrophobic, requiring little or no addition of collector).
