Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process.. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.

Gold electrolysis is the system which obtains gold mud from carbon by desorption and electrowinning. There are two process ways. One is in normal temperature and pressure desorption and electrolysis. Another is in high temperature and pressure desorption.

Gold parting is the separating of gold from silver.Gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver; gold and silver alloy is called electrum.With the advent of coinage, methods had to be invented to ...

Desorption electrolysis system process. In gold electrowinning process, when the electrolysis equipment is added with anions which are more easily absorbed by activated carbons, Au（CN）2ˉ is replaced by anion and the gold desorption is achieved. After the carbons loaded with gold are desorbed, the pregnant solution is processed via ionization.

Fill hydrogen peroxide H 2 O 2 40ml per 2000 ml melted gold chemical water. stir it together and wait for 5 minutes. You have to fill hydrogen peroxide H 2 O 2 in melted gold chemical water to destroy cyanide chemical structure. So, it is not fully element. It cannot melt gold. If we do not fill hydrogen peroxide H 2 O 2 That makes the next step gold piece melted and change into solution.

A new and effective electrochemical process for the extraction of gold, silver and other precious metals from low-yield ores containing relatively large quantities of other non-precious metals wherein a novel electrolytic dissolution cell is provided for the controlled production and efficient utilization of chlorine as a solubilizing agent for the removal of the precious metals from the ore ...

Desorption electrolysis system designed by Xinhai, is used for the extraction of gold from gold loaded carbon by cyanidation/cyaniding process. Principle: Add some anion more easily absorbed by activated carbon to replace Au (CN) 2ˉ and realize the desorption of gold. The pregnant solution from

At this point, treated high grade ore is leached with cyanide and gold is collected onto activated carbon with the cyanide solution being recycled. The gold-carbon mixture is put in a vessel where the gold is removed chemically. The carbon is then recycled. The gold is then extracted from the solution by electrolysis or chemical substitution.

This assures a rapid interface between the carbon and the gold loaded cyanide solution. Granular, hard carbon is used, in the size range of 10-16 mesh. The carbon is then removed by screening, across a carbon screen, allowing the liquid and finely ground ore (-100 mesh) to pass through easily, and retaining the carbon on the screen.
