    The basic design and operational layout of heap leach projects are very similar at all facilities. Lowgrade ore (typically from a surface mine) is stacked 15 to 50 + feet high in engineered heaps on sloped (1 to 6%) relatively impermeable pads and a weak alkaline cyanide solution is sprayed over the ore.

    Carbonaceous gold ores can have the carbon adsorb the gold onto its surface and as a result will not be recovered from the pregnant solution. Leaching gold from sulfide ores is difficult at best. Generally the recovery for cyanide leaching of sulfide or refractory ores is no better than 30% which is not a worthwhile venture.

  • The Metallurgy of Cyanide Gold Leaching An Introduction

    Depending on all the other variables and costs associated some projects can be viable with a gold grade as low as 0.5 g Au per tonne of ore with sufficient tonnages. 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.

  • Gold cyanidation Wikipedia

    Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination complex. It is the most commonly used leaching process for gold extraction.
