1.Gold pool leaching process working principle
The gold ore pool leaching process is a common method for extracting gold ore. It uses a mineral processing agent as a solvent, and the ore comes into contact with the solvent to produce a chemical reaction, resulting in the formation of gold complexes. Then, through adsorption, washing, and electrolysis, the gold is extracted from the solution.

2.Gold pool leaching process application
Widely used in the extraction of various gold mines, as well as precious metals such as vanadium, zinc, nickel, and molybdenum, and in the treatment of smelting slag and tailings containing components.
In the gold ore beneficiation process, we also have: cil / cip process plant , heap leaching process plant , small scale gold processing plant etc
3.Gold pool leaching process steps
1. Ore crushing:
The raw ore is crushed into particles by a crusher, and the particle size is determined according to the permeability of the mineral, in order to better contact with the solution.
2. Add auxiliary materials and mix well:
Add lime and permeable materials to the crushed ore, and stir evenly
3. Ore leaching:
Place the minerals on top into a gold mining pool and add a solution containing a gold dressing agent to ensure full contact between the ore and the solution.
4. Reaction:
The gold in the gold ore reacts with the gold dressing agent to form a gold complex. The reaction time is generally long, taking several tens of hours or even days.
5. Adsorption:
After the reaction, the solution is subjected to an adsorption step and activated carbon or other materials are used to adsorb the gold complex.
6. Washing:
The adsorbed solution is subjected to a washing step to remove impurities and residual mineral processing agents from the adsorbent, resulting in a pure gold solution.
7. Analysis or electrolysis:
The washed solution is electrolyzed, and gold is precipitated from the solution and deposited on the cathode through the action of current between the anode and cathode.
8. Impurity removal:
The gold obtained by electrolysis is subjected to impurity removal treatment to remove other impurities and obtain high-purity gold.

4.Gold pool leaching process features
1. High gold extraction rate, simple process, low operating cost, suitable for low-grade gold ores, etc.
2. It is an efficient and economical method for gold extraction, widely adopted globally and becoming one of the main methods for gold extraction.
3. Strict process control and equipment maintenance are required to ensure gold extraction efficiency and product quality.
