Jinmiao Brand New Stone Sulfur Agent (CG505) is a series of environmentally friendly gold leaching agents jointly developed

by Shenyang Jinyao Environmental Protection Technology Co.,Ltd. and China Gold Group Changchun Gold Research Institute,with technical support provided by Changchun Gold Research Institute. In 2015, this environmentally friendly gold leaching technology was promoted by the Ministry of Land and

Resources and successfully selected for the "Advanced and Applicable Technology Promotion Catalogue for Mineral

Resource Conservation and Comprehensive Utilization (FourthBatch)", representing the advanced level of the gold industry in

gold mineral resource conservation and comprehensive utilization. In December 2016,the CG505 series of

environmentally friendly gold leaching products and application technology achievements were recognized by the China Gold

Association as reaching international advanced levels, among which the "collaborative leaching" and "in-situ treatment"

technologies reached international leading levels and were awarded the first prize in Science and Technology by the China Gold Association in 2016.

inmiao brand new stone sulfur agent (CG505) is a series of high-tech products that can completely replace the efficient

leaching of sodium cyanide solid cash. This environmentally friendly gold leaching agent is suitable for various gold

containing ores and materials as well as related leaching processes, mainly including gold and silver oxide ores,primary

ores, cyanide tailings, gold concentrates, roasting residues, anode slime, etc. It is suitable for leaching processes such as

heap leaching, pool leaching,carbon slurry, stirring leaching, etc.

Jinmiao brand new stone sulfur agent (CG505) can directly replace the efficient leaching of sodium cyanide solid cash

without changing the original cyanide leaching process;At the same time, this product is equipped with a dedicated leaching

tailings slurry treatment agent, which can make the leaching tailings slurry meet the national environmental protection

discharge requirements, separate the leaching tailings from the category of hazardous waste containing cyanide tailings,and

facilitate the safe production of enterprises.

Jinmiao Brand New Stone Sulfur Mixture(CG505) has the advantages of low toxicity, environmental protection,high

recovery rate, strong leaching ability, good stability, strong adaptability to ores, simple and convenient operation methods,

equivalent dosage to sodium cyanide, significant reduction in comprehensive cost (leaching+environmental treatment)

compared to sodium cyanide, and convenient storage and transportation.

Low toxicity

The toxicity of Jinmiao brand new stone sulfur mixture(CG505) has been significantlyreduced compared to sodium cyanide. After identification by relevant national authoritative institutions, this product belongs to ordinary goods, has no explosion risk, no oxidant risk, does not belong to flammable dangerous goods, does not belong to 6.1 toxic goods, and does not belong to radioactive dangerous goods. It can be safely transported by road, railway, sea, or air; Convenient for transportation, storage, and use by production enterprises, providing convenient conditions for their safe production.

The usage process is simple

Jinmiao brand new stone sulfur agent (CG505) can be used as a substitute for sodium cyanide, which can directly replace the efficient leaching of sodium cyanide without changing the original cyanide leaching process and adding new equipment, and the production indicators can be at the same level as sodium cyanide.

The gold leaching index is equivalent to sodium cyanide

Jinmiao brand new stone sulfur agent (CG505) can handle various gold containing materials, such as oxidized gold bearing ore, sulfur-containing easily leachable ore, roasting slag, gold concentrate, etc. Industrial applications have shown that gold in the

leaching solution can be recovered using activated carbon adsorption and zinc powder replacement methods.

Wide application range

Jinmiao Brand New Stone Sulfur Agent (CG505) is developed specifically based on the characteristics of different types of ores, with a wide range of applications and the ability to meet the leaching characteristics of ores from different levels. Targeted development of environmentally friendly gold leaching products suitable for ore properties can achieve efficient gold leaching with the lowest consumption of reagents, creating more economic benefits for enterprises.

The gold immersion index is superior to similar products

Using a gold ore from Liaoning and a gold concentrate from Hebei as raw materials, CG505 was used for leaching, and compared with similar products purchased on the market. The results showed that under the same dosage of reagents, the leaching index ofCG505 was superior to other reagents

Equipped with dedicated environmentally friendly treatment agents,

After leaching the ore with the Jinmiao brand new stone sulfur agent (CG505), a dedicated environmental treatment agent is added, which can make the leaching tailings slurry meet the national environmental discharge requirements, separate the leaching tailings from the hazardous waste category, and facilitate the safe production of enterprises.

The Jinmiao brand new stone sulfur agent (CG505) can not only reduce the transportation and storage costs of leaching agents for enterprises, but also significantly reduce the comprehensive cost (leaching+environmental treatment) compared to sodium cyanide leaching through the combined effect of leaching agents and specialized environmental treatment agents.
