The Metallurgy of Cyanide Gold Leaching An Introduction

Oct 20, 2014With lower gold grades beneficiation (usually flotation) is often used ahead of leaching to increase the grade of Au and reduce the quantity of ore to be leached. Nature of Gold The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 m of

Gold Extraction and Recovery Processes Semantic Scholar

The flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyrites. In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation.
