The Metallurgy of Cyanide Gold Leaching An Introduction

20, 2014 · With 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 0.20.5 µm of surface depth per hour in a cyanide leach.
