Gold-Copper Ores - ScienceDirect

Jan 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 ...

Recovering Gold through the Froth Flotation Process ...

Feb 06, 2018· Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules.

gold leaching either using the same process at elevated temperature (40–60 °C), as patented by the authors, or using a cyanidation process. Copper selective leaching will reduce the gold losses due to a cementa-tion mechanism of gold in the presence of metallic copper as all of the metallic copper will dissolve in the pre-leaching stage.
