Re-yingcai® Eco-Friendly Gold Dissolving Agent is a new-generation cyanide-free gold leaching reagent formulated with organic chelating and inorganic complexing components. It contains no cyanide ions and is designed for safer gold recovery in mines and precious-metal recycling operations. The product is suitable for heap leaching, vat leaching, carbon-in-pulp processing and the recovery of gold from plated scrap. It can be introduced into many existing cyanidation lines without major equipment modifications, balancing recovery efficiency, operational safety and environmental compliance.
Product Features
-
High Gold RecoveryDelivers strong gold-leaching performance, with typical recovery rates of 70%–80% and over 95% for high-grade oxidized ores with low impurity levels, helping improve processing capacity and mine economics.
-
Lower Operating CostCompared with conventional extraction methods, the optimized reagent consumption can reduce chemical use per tonne of ore and help lower overall production costs.
-
Low-Toxicity FormulaDesigned with worker safety and environmental protection in mind, this modern cyanide-free formulation offers lower toxicity and reduces pollution risks compared with traditional cyanide-based processes.
-
Environmentally ResponsibleIts low toxicity, high efficiency and degradable formulation help reduce environmental impact, support cleaner tailings management and meet sustainable mining requirements.
Product Parameters

Product Name Eco-Friendly Gold Dissolving Agent Model YCA02004S Appearance Off-white powder Applicable Ore Types Oxidized ores, sulfide ores and other gold-bearing materials Storage and Transport Keep dry, protect from water and store separately Leaching Performance High Packaging 25 kg/bag
High Recovery and Fast Leaching
Provides strong gold-dissolution performance. Typical ores can achieve recovery rates of 70%–80%, while suitable high-grade oxidized ores may exceed 95%. The faster leaching cycle helps release more gold from the ore and improve plant throughput and economic returns.
Cyanide-Free, Low-Toxicity Formula
Contains no highly toxic cyanide ions. The reagent is degradable, and process wastewater can be treated through a comparatively straightforward neutralization procedure. Lower toxic residue in tailings reduces soil and water contamination risks and supports green-mine standards.
Versatile Across Leaching Processes
-
Compatible with mainstream heap, vat and carbon-in-pulp leaching processes. Existing cyanidation production lines generally require no major modification, and the reagent can be used for various gold ores, gold-bearing tailings and gold-plated scrap.
Simplified Storage and Safer Handling
-
Not classified as a highly toxic cyanide chemical, simplifying procurement, storage and transport requirements. It produces no toxic cyanide gas during normal use, helping reduce worker exposure risks and streamline site safety management.
