Gold-Copper Ores ScienceDirect

01/01/2016· Today, flotation is commonly used in the processing of primary copper–gold ores to produce a copper concentrate containing gold as a co-product, where the gold is recovered as a byproduct of copper smelting and refining (La Brooy, 1992). The gold is usually discrete and either free, associated with copper sulfides or associated with iron-sulfide minerals. Due to this variable gold association, significant gold is often not recovered with the copper

Gold-copper ores ScienceDirect

01/01/2005· The association of gold and copper mineralization in commercially viable ore is a common occurrence. At one end of the spectrum is the predominantly copper ore, which contains levels of gold mineralization. This would be uneconomic to mine for its gold content, but the gold provides a significant opportunity value. The gold is recovered with the copper and is eventually recovered from the residues of copper

Treatment of copper-rich gold ore by cyanide leaching

Gold CIL & CIP Gold Leaching Process Explained CCD

02/01/2013· The carbon-in-pulp process is used to treat low grade gold and/or silver ores. The ore is first ground in a ball mill which operates in closed circuit with a cyclone or similar sizing device. This is done to produce a feed suitably sized so that subsequent leaching is rapid. The ground ore overflowing the sizing device generally runs at 25 to 35 percent solids. First it is passed through a

Gold Metallurgy and Leaching Process

24/06/2015· Leaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent. In extractive metallurgy, of gold, it is the process of dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc., to achieve either one or two purposes:
