Solutions&Cases

Traditional cyanide-based gold extraction has high toxicity and poses major safety and environmental risks. In complex gold ores, “preg-robbing” substances such as copper, arsenic, and organic carbon may interfere with gold leaching, reduce recovery rates, and increase processing costs. Some alternative reagents also face challenges such as high cost, poor stability, or limited application range.

YINGCAI provides an eco-friendly gold extraction reagent as a safer alternative to cyanide. Based on a low-toxicity organic compound system, the reagent offers good biodegradability and helps reduce environmental risks from the source.

For complex gold ores, specific components in the reagent can react preferentially with interfering minerals, reduce preg-robbing effects, or support oxidative pretreatment to break encapsulation and expose gold particles more effectively. The reagent maintains stable leaching performance under a wider pH range and lower dosage conditions, making it suitable for fine gold, encapsulated gold, and complex ore beneficiation scenarios.

This solution helps build a safer on-site operating environment, simplify tailings and wastewater management, improve gold recovery, and reduce overall reagent costs, achieving a better balance between safety, environmental compliance, and economic efficiency.
