Mineral Treasure environmentally friendly gold extractant is an innovative product that can completely replace highly toxic sodium cyanide. Our company has completely independent intellectual property rights. The product has the characteristics of non-toxic and environmentally friendly, stable performance, strong practicality, high leaching rate, faster recovery, lower usage, lower cost, easy use, and convenient transportation.

Our pharmaceutical R&D engineers have conducted extensive laboratory technology research and development based on various types of gold ores with different properties (raw ore, tailings oxide ore, gold concentrate, cyanide tailings, smelting pass, etc.), and have also achieved technical indicators in multiple beneficiation plants. The products have been quantitatively used in multiple mining sites at home and abroad, with low toxicity and environmental protection, and have been identified by national quarantine and testing departments as ordinary goods. The pharmaceuticals can be shipped by public logistics methods such as road transportation, railway transportation, and air transportation.

Environmentally friendly gold extractants are used in the heap leaching, pool leaching, and carbon slurry (agitation leaching) processes of gold and silver oxide ores, primary ores, sulfide ores, cyanide tailings, and gold concentrates. The process flow is the same as that of using sodium cyanide, and precious and lean liquids can be reused in production. Activated carbon adsorption is the best method for extracting gold from precious liquids. The leaching effect of gold is best when the ambient temperature is above 10 ° C. Compatible with cyanide extraction method.

1. Alkalinity adjustment: The product belongs to alkaline inorganic compounds, and lime and caustic soda (add more lime and try to add less caustic soda) are used as stabilizers for this product. The pH value of the ore heap (slurry) is 11 ± 1. After the raw ore is piled up or fed into the pool, the alkalinity pH value is adjusted to 11+1 by returning (or discharging) water (detected with precision pH test paper 9.5-13).
2. Dosage: The dosage is approximately 10.0-20.0 parts per ten thousand (1000-2000 grams per ton of ore), and the properties, grade, and acidity of the ore will affect the dosage. The actual dosage can be calculated based on the concentration of the medicine.
3. Dosing method: After the block shaped agent is fully dissolved in clean water at room temperature, it can be used (usually accelerated by flowing water or thorough stirring; during heap leaching, a dosing pool can be built next to the lean solution pool to allow the return water after carbonization to directly flush the gold selector into the lean solution pool).

Before adding medication for the first time, adjust the alkalinity to at least 10. When the water in the pool is low, pour both the alkalinity and medication at the same time. Two flushing buckets can be used to separately pour lime (or caustic soda) and gold selection agent into the medicine water tank (lean solution tank) or into the medicine water tank for dissolution, ensuring uniform concentration of medicine in the tank. If it is a heap spraying process, dosing and spraying can be carried out simultaneously.

Initial stage: Control the concentration of the medicine to be around 1% (i.e. the ratio of medicine to water is 1:1000, that is, 1 kilogram of medicine plus 1 cubic meter of water), for 7-10 days.
Mid term: Control the quality concentration of the medicine to around 0.5% for 20-30 days.
Later stage: Control the quality concentration of the solution to around 0.3% and wait until the end of adsorption
