separating flotation Copper from pyrite

SEPARATION OF COPPER MINERALS FROM PYRITE -

A process of separating copper minerals from pyrite wherein a flotation concentrate containing copper minerals and pyrite is reground in the presence of lime and subsequently conditioned at a pH of 12.0 or more for a predetermined period sufficient to depress the pyrite, with optional additions of sulf-hydryl collector, cyanide and dispersing agent, and the conditioned pulp is subjected to flotation.

2018-9-1  For the copper tailings, the objective of the flotation is to detach the copper minerals from other sulfide minerals (usually pyrite) and the gangue minerals. The main difficulty lies in the depression of pyrite, which conventionally proceeds in high pH conditions by using large amounts of lime (CaO).

Chalcopyrite (Cu) Sphalerite (Zn) Separation by Flotation

2016-4-14  The Problem with separating Copper from Zinc by flotation. The treatment of heavy sulphide ores of copper containing zinc and pyrite is often extremely difficult particularly if soluble copper and sulphates are present. This is usually the case in ore deposits near the surface or in tropical countries where the annual rainfall is quite high.

2017-5-3  Sodium silicate was somewhat effective in causing a differential or selective flotation of copper, as chalcopyrite from pyrite by keeping pyrite from floating. Sodium hydroxide and sodium sulfide gave, in most cases, a distinct separation of sphalerite from chalcopyrite; i.e., a high copper and low zinc by suppressing the flotation
