700 TPD rock gold mine project in Zimbabwe was contracted by Xinhai, the gold mine is mainly quartzite, mostly are oxidized ore and raw ore with low sulfur. The dressing part adopts gravity separation + all sliming cyanided carbon slurry process, namely desorption electrolysis system for gold extraction.
electrolysis on aquaregia for gold Solution for ore mining
Direct electrolysis of gold If the gold content of a metallic scrap is high and the impurity level of silver, platinum, gold refining electrolysis, scrap gold refiners scrap gold refining aqua regia gold refining hev consulting on precious metal . aqua regia gold refining for low cost separation of gold, silver, platinum and palladium from
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.
Desorption is a phenomenon whereby a substance is released from or through a surface. The process is the opposite of sorption (that is, either adsorption or absorption).This occurs in a system being in the state of sorption equilibrium between bulk phase (fluid, i.e. gas or liquid solution) and an adsorbing surface (solid or boundary separating two fluids).
The Moebius Process of Purification of Gold by Electrolysis is now in successful operation and is said to be specially suitable for refining copper bullion containing large proportions of silver and gold with small quantities of lead, platinum, and other metals, but is chiefly used in parting dore silver containing not more than 20 per 1,000 of base metals.

Wanting to build an electrolytic gold scrap Finishing
May 14, 20150183;32;Wanting to build an electrolytic gold scrap refining machine. having invented the Gold Bug system and can tell you that this system can often recover metals to a fraction of a ppm. A company that used our system for copper recovery reported that they were able to bring the copper concentration from 2 ppm to 50 ppb Electrolysis
Desorption does not require sodium cyanide, which reduces cost and averts pollution. Work Principle. In gold electrowinning process,when the electrolysis equipment is added with anions which are more easily absorbed by activated carbons, AuCN2 is replaced by anion and the gold desorption is achieved.
