In a significant stride towards sustainable mining, our company, Yantai Billion Thai—a specialized manufacturer and innovator in non-cyanide gold extraction—has successfully developed and patented an environmentally friendly gold leaching agent. Approved with national invention patents and certified by multiple environmental standards, this product is poised to transform traditional gold extraction processes without compromising efficiency.
Extensively tested and adopted in industrial applications by more than 100 gold mining operations worldwide, our leaching agent delivers performance comparable to—and often superior to—sodium cyanide. Crucially, it requires no alteration to existing cyanidation equipment or process flows, enabling a seamless and sustainable transition for mines of all scales.
Our agent is versatile and fully compatible with common gold recovery processes, including:
Carbon-in-Pulp (CIP)
Heap Leaching
Tank Leaching
Carbon Adsorption
Zinc Displacement
This makes it an ideal, drop-in replacement for sodium cyanide, allowing operations to maintain their existing workflow—from crushing and grinding to leaching and recovery—while significantly reducing environmental impact.
Compared with traditional sodium cyanide, our eco-friendly leaching agent offers multiple tangible benefits:
Higher Environmental Safety: Non-toxic formulation reduces ecological impact and compliance risks.
Simpler Export Compliance: Easier export qualifications and streamlined international logistics.
Convenient Procurement: Straightforward purchasing procedures with minimal regulatory barriers.
Easier Transportation: Classified as non-hazardous, facilitating safer and lower-cost shipping.
Reduced Dosage & Lower Cost: Typically requires less reagent per ton of ore, improving cost efficiency.
Higher Leaching Rate: Enhanced gold dissolution leads to improved recovery performance.
Based on accumulated operational data, our agent demonstrates consistent effectiveness across ore types:
Oxidized ore (~10 g/t): 1–2 kg per ton
Sulfide ore (~10 g/t): 3–5 kg per ton
Primary ore (~10 g/t): ~5 kg per ton
The agent is applied in the same manner as sodium cyanide—simply diluted and introduced into the leaching circuit. Water quality typically used in cyanide processes does not impair its effectiveness. Moreover, the presence of calcium ions (Ca²⁺) does not interfere with the leaching reaction or gold dissolution, although long-term use in hard water may contribute to mild scaling in carbon adsorption systems, similar to conventional setups.
By combining proven results, operational familiarity, and a strong environmental profile, our leaching agent represents a reliable and responsible choice for the future of gold extraction.
We are a dedicated producer and R&D innovator focused on providing effective and sustainable alternatives to traditional gold leaching chemicals. Our solutions are engineered to help the mining industry advance towards greener practices without sacrificing productivity or profitability.
