Gold cyanidation Anfacal

Gold cyanidation (also known as the cyanide process or the MacArthur Forrest process) is a metallurgical technique for extracting gold from low grade ore by converting the gold to a water soluble coordination complex. It is the most commonly used process for gold extraction.[1] Production of reagents for mineral processing to recover gold, copper,

The Metallurgy of Cyanide Gold Leaching An Introduction

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. Cyanidation is used for gold that is distributed finely through a mineral matrix.

What is Gold Cyanidation? (with picture) wisegeek

Gold cyanidation, also called cyanide leaching, is a process used to extract gold from raw ore taken from the ground. It uses cyanide to dissolve the gold within the rock, which, itself, is not soluble in cyanide. The gold is then drawn out in a liquid form that can be treated to remove the cyanide.

A number of different methods can be used to separate gold from its ore, but one of the more common methods is called gold cyanidation. In the process of gold cyanidation, the ore is crushed and then cyanide (CN) solution is added so that the gold particles are chemically separated from the ore. In this stage of the process, gold is oxidised.
