  • The Metallurgy of Cyanide Gold Leaching An Introduction

    The Metallurgy Of Cyanide Gold Leaching An Introduction

    Oct 20, 2014 Nature of Gold The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 m of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.
