cyanide for gold processin

Gold cyanidation

Gold cyanidation (also known as the cyanide process or the MacArthur Forrest process) is a hydrometallurgical technique for extracting gold from low grade ore by converting the gold to a water soluble coordination complex. It is the most commonly used leaching process for gold extraction.

The Metallurgy of Cyanide Gold Leaching An Introduction

Nature of Gold The surface of a gold particle will typically be dissolved at a rate of around 0.2 0.5 181;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.


Process of Cyanide Gold Extraction

Here I present an Process EXAMPLE of Gold Extraction Cyanide in which the cyanidation feed consists of a pyrite concentrate floated after the selective flotation of a copper gold concentrate.

Gold Chemistry Leaching Processes CHEMISTRY of the CIP

High gold cyanide and cation concentrations, low temperatures, low anion concentrations and active carbon drive the gold cyanide onto the carbon. During elution, lack of cations (Ca2+, Mg2+, etc), high anion concentration (CN , OH ) and high temperatures will disrupt the equilibrium and remove gold cyanide from the carbon.
