The process design of gold leaching and carbon

Cyanidation has a history of more than 200 years since it was applied to gold and silver ore extraction in 1887. At present, cyanidation is still one of the main gold extraction process due to its high recovery rate, high adaptability to ore and local production.. Generally, cyanidation methods can be divided into two categories: agitation cyanidation and percolation cyanidation.

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. This produces a small volume of solution with a high gold concentration.

The content of gold in the ore is extremely low. In order to extract gold, we need to crush the large ore rock into small pieces first, grind it, and then use appropriate gold processing methods to separate the gold from the ore, get the gold ...

What are the Differences Between CIP Process and CIL ...

01 1. CIP process. The typical CIP process consists of cyanide leaching, activated carbon adsorption, desorption, and carbon regeneration.. The new (or regenerative) activated carbon is added in the last adsorption tank, the movement direction of the carbon is contrary to the flow direction of slurry, and finally, the gold loaded carbon is absorbed from the first adsorption …
