Product Description
Professional Equipment for Refractory Gold Ore Processing and Extraction
Gold is often locked within sulfide minerals like pyrite and arsenopyrite as fine-grained or sub-microscopic particles. The cyanide leaching solution cannot access and extract the gold without first breaking down these host minerals.
Conventional Gold Extraction Process
The conventional gold extraction process primarily relies on two core technologies: "Flash Leaching" and "One-Step Gold Reduction." The well-established cyanidation method typically requires a leaching time of 36 to 96 hours.
- Complete cycle from carbon adsorption to finished gold production takes 15-30 days
- Recovery rate generally between 50% and 70%
Advanced Extraction Method
In contrast, the new extraction method achieves leaching in just 12 to 24 hours and enables direct production of 99.99% pure gold from the pregnant solution.
The entire process is environmentally friendly; the leaching agent is non-toxic and harmless, even possessing disinfectant properties. The leachate can be fully recycled after use, achieving true zero discharge of chemicals.
Challenges in Gold Dissolution
The presence of reactive components in the ore can severely hinder gold dissolution. These components engage in competitive side reactions with both cyanide and oxygen, resulting in excessive reagent consumption and significantly impeding the leaching process.
