United Chemical, TuXingSun Mining, and Henan Lingbao Gold Mine Jointly Establish a Cyanide-Free Mine

Pioneering Sustainable Mining Practices with Jinchan Eco-Friendly Gold Leaching Agent

The Jinchan environmentally friendly gold leaching agent has been applied industrially at the Wenyu Gold Mine in Lingbao, Henan Province, particularly for the extraction of precious elements like gold. This project has a gold content of 9 grams per ton and an Inorganic carbon content of 10.94%. The maximum advantage of this project is its environmental compliance, including the use of the Jinchan eco-friendly gold leaching agent as a substitute for sodium cyanide. This method not only ensures high-efficiency Gold extraction but also minimizes the environmental impact of the ore processing process.

When the grinding fineness is -0.074 mm, with a content greater than 90%, a pulp concentration of 40%, a lime dosage of 3 kg/t, an alkaline pretreatment time of 2 hours, a Jinchan eco-friendly gold leaching agent dosage of 600 g/t, and a leaching time of 24 hours, the gold Leaching rate can reach 95.60%. Compared to cyanide leaching, the leaching rate increases by 1.4%, reagent usage decreases by 200 g/ton, and the leaching time is shortened by over 12 hours. Furthermore, a leaching Toxicity analysis of the Jinchan eco-friendly gold leaching agent's residue showed that the leaching toxicity values for cyanide, copper, lead, zinc, and arsenic in the tailings are all within national standard limits and can be directly discharged without the need for detoxification.

The key factor in the successful trial of the full-lime cyanidation project is the use of the Jinchan eco-friendly gold leaching agent. This leaching agent is specially designed to facilitate the leaching and absorption process sustainably. The Jinchan leaching agent employs a four-stage leaching and five-stage absorption process, ensuring that even with the presence of inorganic carbon, the gold leaching effect is not affected. This is a significant breakthrough for the project, as it demonstrates that eco-friendly alternatives can be as effective as traditional methods. Compared to cyanide leaching, the leaching rate can improve by 1.4%, the consumption of reagents is reduced by 200 grams per ton, and the leaching time is shortened by over 12 hours, resulting in good leaching effects and significant economic benefits.

The substitution of sodium cyanide with the Jinchan eco-friendly gold leaching agent reflects the mine's commitment to Environmental protection. Sodium cyanide has long been the industry standard for gold leaching, but its toxicity poses significant risks to the environment and human health. In contrast, the Jinchan agent provides a safer and more sustainable alternative, ensuring that the gold extraction process does not come at the expense of environmental degradation. This shift towards eco-friendly practices benefits the local ecosystem and sets a positive example for the broader mining industry.
