Sulphide Gold Ore Treatment by Leaching and Flotation …

With the advent of flotation and the fact that gold either free or finely disseminated in pyrite, etc., could be floated, many possibilities opened up for the treatment and concentration of gold ores. It also provided the means of working ore bodies hitherto considered unprofitable or metallurgically impossible for cyanide treatment. Two examples are the large low-grade ore bodies which require very fine grinding and …

Flotation of Gold and Gold-Bearing Ores - ScienceDirect

01/01/2016· Most of the reported fundamental work on the flotation of gold has been conducted using high-purity gold and gold–silver alloys with the purpose of determining collector–gold interactions and the nature of adsorption of collector ions or molecules onto the gold surface. In addition, some work has been conducted to decide whether pure gold has a natural hydrophobicity and hence some degree of …

Optimisation of gold recovery by selective gold flotation ...

Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free. Gold does float readily, however, and the free gold can be selectively floated away from an ore containing sulphides. This may be an alternative treatment route for gold room applications where fine gold …
