The quick leaching method for gold mines involves several key steps:
Crushing and Fine Grinding: The gold ore is first crushed into small particles and then finely ground to ensure maximum surface area exposure for efficient leaching.
Slurry Formation: A mixture of bromide salts, iron salts, and acid is added to the ground ore, forming a slurry that facilitates the leaching process.
Agitation: The slurry is agitated at speeds between 100 to 800 rpm under normal temperature and pressure conditions. This step ensures that the chemical reaction between the gold particles and the leaching agents is sufficiently intensive to achieve high leaching efficiency.
Filtering and Washing: After the leaching process, the slurry is filtered to separate the gold from the residue. The residue is washed away, leaving behind the leachate (filtrate) containing the dissolved gold.
Gold Recovery: Conventional methods are employed to recover the gold from the leachate, typically involving further processing such as precipitation or electroplating to produce pure gold products.
This method boasts several advantages:
Rapid Leaching Rate: The process achieves a gold leaching rate exceeding 90% in a short time.
Simplicity: The production process is straightforward and requires minimal equipment complexity.
High Efficiency: The leaching efficiency is significant due to the optimized mixture of chemicals and agitation conditions.
Broad Applicability: This method can handle various types of gold ores, including challenging ones like high-sulfur, high-antimony carbonaceous gold ores, without requiring prior treatment of the ore.
Environmental Friendliness: The absence of harmful emissions such as sulfur dioxide or oxidized antimony makes this process eco-friendly. Additionally, the non-toxic nature of the reagents used ensures minimal impact on human health and the environment.
Overall, the quick leaching method offers a cost-effective and sustainable solution for gold extraction, particularly suited for mines with complex ore bodies.
