cu and zn sulphide flotation technique

Distribution of Sb minerals in the Cu and Zn flotation of

15-10-2015· Flotation tests on Rockliden composite samples have shown that the threshold of 0.2 wt% Sb is exceeded in the Cu–Pb concentrate even if the Sb grade of the blended feed material is below this value (Bolin, 2010, Minz, 2013).This is related not only to the flotation behaviour of common Sb minerals but also to the mineral association and the degree of liberation, which are suspected to

CANATUAN CU/ZN FLOTATION METALLURGY

The second phase of the mining operation required construction and development of a sulphide flotation processing plant. The project began in early 2007 and was commissioned in November 2008. The plant was initially designed to process high Cu-low Zn ores (with Cu to Zn ratio > 5:1) to produce marketable copper concentrate only.

Literature: Flotation is the most versatile mineral processing technique that has made it possible to mine most low grade & complex ore bodies that would have been regarded as uneconomic. Though complex and not completely understood, flotation has been used to achieve specific separations from complex ores like Pb-Zn-Cu, Pb-Zn & Cu-Zn etc. Initially developed for sulphide ores, flotation has

inorganic depressants for sulphide copper ores flotation

Being pyrite (iron sulphide) the main gangue mineral associated with copper sulphides, it is of the main interest to study conditions to obtain selective depression of pyrite. In the case of Cu–Mo flotation plants, inorganic depressant reagents are commonly used, such as cyanide, Na 2 S, NaSH or some sulphites.
