Notes On Withdrawal Agents

1. It is recommended to use specialized coconut shell adsorption activated carbon or zinc powder as an adsorption medium or reduction auxiliary collector (charcoal slurry method uses specialized activated carbon for gold extraction).
2. The use of gold extraction agents at temperatures above 15 ℃ has a better effect.
3. Due to the fast gold leaching speed, it is recommended to regularly test the gold grade, pH value, and concentration of the gold extraction agent in your solution.
4. Strong oxidants such as hydrogen peroxide and potassium permanganate are not recommended to be added together with gold extraction agents (they can be used for pretreatment).
5. The use of reagents such as chlorine water, sodium sulfide, potassium ferric chloride, lead nitrate, sodium hypochlorite, etc. in the pretreatment of complex ores does not affect the leaching of gold with gold extraction agents.
