【 Capacity 】: ≥3.5kg/t
【Improvement】: Desorption electrolysis system consists of electrolysis equipment including desorption column and the electrodeposition tank
1、In the high temperature (150℃) and pressure (0.5MPa), the desorption rate reaches 98%.
2、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.
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.
