Distribution of Sb minerals in the Cu and Zn flotation of

Oct 15, 2015· 1. Introduction. Generally, antimony (Sb) is known to occur as a trace element in massive sulphide ores. It is regarded as penalty element because it lowers the quality of Cu concentrates produced from ore and sent to the smelters (Minz, 2013 and references therein).Typically, penalty charges are imposed for Sb contents of 0.1–0.3 wt% in copper (Cu) concentrates (Larouche, 2001).

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.

Selective Separation of Cu, Zn, and As from Solution by

Oct 23, 2006· Abstract. The selective precipitation and flotation of copper, zinc, and arsenic ions from dilute aqueous solutions were investigated. Phase separation was accomplished effectively by the dissolved-air technique for the production of fine gas bubbles, and a short-chain xanthate was applied as the collector for copper ions, dialkyldithiocarbamate for zinc, and ferric sulfate for the pentavalent
