Low-Grade Gold Mine Soaking Method for Extracting Gold

     

Low-Grade Gold Mine Soaking Method for Extracting Gold:

Preparation of Low-Grade Gold Ore: After removing surface mud, dirt, and other impurities from the low-grade gold ore, crush and screen it to select ores with particle sizes less than 70mm. Mix this with lime in a ratio of 3:1 (ore:lime) and stir uniformly to form a mixture. Form piles with this mixture.

Impregnating Compound : Adjust the pH of the solvent to between 10-12, creating a basic solution. Add cyanide to form the dye solution.

Spraying: Spray the dye solution continuously over the ore piles to produce the pregnant solution.

Gold Adsorption on Activated Carbon: Pump the pregnant solution through activated carbon columns filled with activated charcoal. The gold complexes in the solution are absorbed by the activated carbon, resulting in loaded carbon containing gold and a low-gold content solution (pregnant solution).

Reprocessing Low-Gold Solution: Recycle the low-gold content solution by repeating steps 2, 3, and 4.

Refining Raw Gold: Process the loaded carbon from step 4 to obtain raw gold.
