process flow of gold processing mills

Gold extraction - Wikipedia

Gold extraction refers to the processes required to extract gold from its ores. This 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 small gold

The process design of gold leaching and carbon-in-pulp

This is done by contacting the carbon with a solution of sodium cyanide (0.1 to 2% by mass) and sodium hydroxide (0.1 to 2% by mass) at high temperatures (90–120°C). This results in the reversal of the adsorption process with most of the gold desorbing from the carbon back into solution.

The Mining Process – Waihi Gold

A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

The mill also includes the processes of attrition and impact, although these actions are limited if the material is easily reduced by cutting and the screen limiting discharge has large perforations. The mill consists of a rotating shaft with four attached parallel knives and a screen occupying one fourth of the 360 degree rotation. The mill is best used to crack whole grains with a minimum of
