The metallurgical process. The Ergo operation currently has two metallurgical plants in operation: Once the gold has been eluted, it undergoes a process called electrowinning where the gold is precipitated, calcined and smelted in the existing smelthouse.
Gold roasting is a process, applicable to refractory ores and concentrates that contain sulfide sulfur, organic carbon, and potentially arsenic. Removal of these compounds is necessary to achieve high gold recovery (gt;90%) during cyanide leaching. Gold roasting is typically a metallurgical fluidized bed process.

Gold extraction refers to the processes required to extract gold from its may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of
extraction of gold and the metallurgical processes. Extraction Of Gold And The Metallurgical Processes Extraction metallurgist extraction metallurgists are involved in the recovery of useful metals or minerals such as gold, coal, diamonds, copper and iron, from the ore bodies in which they occur. south africa is a mineral rich country; so there is always a need for extraction metallurgists.

Leaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent. In extractive metallurgy, of gold, it is the process of dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc., to achieve either one or two purposes

More gold is recovered by cyanidation than by any other process. In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the goldbearing solution is separated from the solids.

Cyanide control in the metallurgical process of gold extraction in AngloGold () by Vorster* and Flatman Synopsis AngloGold South Africa region currently consists of twelve gold plants. These plants use a combined total of 20 million of cyanide per annum.
Cyanide control in the metallurgical process of gold extraction in AngloGold () Influence of oxygen Whilst cyanide is one of the major drivers if not the major driver of gold dissolution, it cannot be viewed in isolation particularly in respect to the relationship between cyanide
