Gold Electrolysis Electrolysis Machine Gold Refining

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. This system consists of electrolysis equipment including desorption column and the electrodeposition tank.

Extraction of Gold

The extraction of gold by the cyanide method is of great technical importance. It is effected by lixiviation with a solution of potassium cyanide, the gold being precipitated either by addition of zinc or electrolytically. The process was suggested by Mac Arthur and Forrest in 1385, and is based on the well known solubility of gold in potassium cyanide solution, a phenomenon said to have been

Gold parting is primarily the removing of silver from gold and therefore increasing the purity of gold. The parting of gold from silver has been done since ancient times starting in Lydia in the 6th century BC. Various techniques have been practised salt cementation from ancient times, parting using distilled mineral acids from medieval times, and in modern times using chlorination using the Miller process and electrolysis using the Wohlwill process.

Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX EW solvent extraction/electrowinning.
