Gold Recovery And How To Choose The Right Process

Gold Recovery And How To Choose The Right Process

Free-Milling Gold. Gold ore is considered free-milling when it is easily liberated by grinding and separated from the other minerals. A more technical definition is that you are able to recover over 90 of the gold by a conventional gravity-cyanidation process with low reagent consumption. Free-milling gold can be further classified into low ...

Oct 01, 1995 This initial gold dissolution rate for sample A is between 0.85 and 11.7 X 10-12 moles cm- 3 s - 1 which corresponds to between 18 and 88 gold extraction in 1 h. Fast gold dissolution kinetics favour high ore throughput, reduced cyanide consumption and low impurity content e.g., Cu.

The Metallurgy of Cyanide Gold Leaching An Introduction

The Metallurgy Of Cyanide Gold Leaching An Introduction

Oct 20, 2014 Cyanicides Cyanide is an aggressive compound, and will react and be consumed by a number of mineral species other than gold species known as cyanicides. These reactions must be carefully managed and where possible suppressed to prevent excess cyanide consumption causing the process to become uneconomic.
