The Leachox™ Process | Maelgwyn Mineral Services

Grinding refractory gold ores to below 20 microns and finer, whilst liberating more gold, also liberates many other mineral species which affect the oxidative and cyanide downstream process. In many cases when only ultra fine grinding is used a maximum recovery is reached and grinding finer actually reduces the precious metal recovery. It also dramatically increases the reagent

Treatment for gold ores with high content of carbonaceous

Abstract: Gold ores associated with carbonaceous matter present several difficulties in their extraction due to the ability of this matter to adsorb the aurocyanide complex from gold pregnant solutions, resulting in low extractions by direct cyanidation. This phenomenon is known as preg-robbing. In the present work, a process to effectively recover Au from a highly carbonaceous

Stamp Mills for Processing Gold Silver Copper Ore

A stamp mill is a large mechanical device used to crush ore and extract the desired metals from the host material.
