Gold CIP Production Line adsorbs gold from cyaniding pulp by active carbon including 7 steps: leaching pulp preparation, cyaniding leaching, carbon adsorption, gold loaded carbon desorption, pregnant solution electrodeposit, carbon acid regeneration, leaching pulp. View details
Recently, Shandong Xinhai Mining Technology & Equipment Inc held a board meeting...
In the high temperature (150℃) and pressure (0.5MPa), the desorption rate reaches 98%.
Since desorption and electrolysis does not require different temperatures, it is not necessary to change temperature. The quickness and efficiency of machine dramatically diminishes gross electricity consumption by 1/2-1/4.
Desorption does not require sodium cyanide, which reduces cost and averts pollution.

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, pregnant solution is process via ionization. At last, solid gold is attained.

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. It is featured with efficient and rapid extracting, low consumption, and low cost and high production efficiency. The gold grade is high without reverse electrolysis, realizing the efficient recovery of gold.
