Gold floatation concentrate
Gravitation separation tailings
Clayish oxide gold ore
Cyanide slurry is screened to remove impurities before the adsorption—Prevent the impurities from adsorbing gold and avoid the wood dust blocking the carbon screen;
Activated carbon is polished to grind off sharp corners and edges before entering the adsorption tank—Prevent the activated carbon debris from entering the slurry, then cause the loss of gold.
2. Leaching and absorption:
Add Xinhai coconut activated charcoal into the high-efficient cyanide leaching tank for absorbing the gold from the cyanide pulp then becoming the gold loaded carbon. Then, the activated carbon and slurry are separated by carbon screen.
3. Desorption Electrolysis:
Gold loaded carbon is changed into gold mud and lean carbon in Xinhai desorption electrolysis system.
After the simple pickling and impurity removal process, the gold ingots can be obtained directly by high frequency melting furnace.
5. Regeneration of Desorbed Carbon:
After the regeneration, the lean carbon can be reused by adding a proportion of new activated carbon.
