Adjusting Alkalinity: Gold extractants are typically alkaline inorganic compounds. When using them, lime, caustic soda, etc., need to be added as stabilizers to adjust the pH of the ore heap (slurry) to 11±1. This step is crucial for ensuring the effectiveness of the gold extractant.
Dosage: The dosage depends on the properties, grade, and pH of the ore, generally between 500 and 1000 grams of reagent per ton of ore. A reasonable dosage is key to ensuring both gold extraction efficiency and safety.
Dosage Method: The gold extractant can be used after being fully dissolved in alkaline water at room temperature. Before the first addition, the alkalinity needs to be adjusted to above 10. This step ensures that the gold extractant can effectively react with the ore, improving the gold leaching rate.
Scope of Application: The gold extractant is suitable for gold and silver oxide ores, primary ores, sulfide ores, cyanide tailings, gold concentrates, etc., and is applicable to heap leaching, pond leaching, and carbon-in-pulp processes. These application ranges ensure the applicability of gold extraction agents in various ore processing methods.
