Gold leaching reagent is used to extract gold in cyanidation plant. In recent years, with the adjustment of national policies, especially the implementation of the new “Environmental Protection Law”, the environmental protection pressure of China’s gold mining enterprises is increasing; so is the environmental cost. Eco-friendly gold leaching reagent, which can extract gold efficiently without polluting the environment, are gradually accepted and recognized by major gold mining companies. The subdivided industry of eco-friendly gold leaching reagent is also widely regarded as a “blue ocean” in the market. Since the market space is broad in the future, many enterprises are actively investing in the opportunities brought by this blue ocean.
In fact, the use of cyanidation process in global gold industry accounts for a high proportion, with 99.5% in South Africa, 88.1% in the United States, and 84.9% in Australia. China’s cyanidation gold leaching technology has also been developed rapidly since the 1980s. Now cyanidation has become one of the most widely used processes in China’s gold production. However, as all aspects of pollution and safety involved, sodium cyanide is one of the worldwide mining problems. Therefore, the launch of CNFREE eco-friendly gold leaching reagent can be said to be a major breakthrough in the world’s environmental gold extraction.
Specifically, in gold leaching process, the impurity metal elements (iron, copper, etc.) contained in gold ore consume a large amount of the gold leaching reagent, resulting in high leaching cost, slow leaching speed, and low leaching rate. The impurity metal inhibitor contained in CNFREE eco-friendly gold leaching reagent can form an extremely stable complex with the impurity metal, preventing it from reacting with the gold extraction reagent and reducing the consumption of the gold leaching reagent. Relevant data show that the leaching speed and leaching rate of the CNFREE eco-friendly gold leaching reagent is greatly improved compared with similar products, and the tailing produced requires no special treatment. Compared to sodium cyanide, CNFREE ECO gold leaching reagent can increase the recovery rate of general gold ore by 3%-5%.
Since its promotion to the gold market, CNFREE eco-friendly gold leaching reagent has been continuously improved and optimized in the inspection relying on its own technical advantages, and has been recognized by various gold mining plants in the industry. At present, CNFREE eco-friendly gold leaching reagent has been exported to more than 90 countries and regions.
The era of eco-friendly gold leaching is coming. Standing at the beginning of a new era, CNFREE eco-friendly gold leaching reagent shoulders the hope of development. For many of China’s gold mining companies, CNFREE is not only a company that can help them recycle more gold, but also focuses on their sustainable development. In the future, relying on science and technology, CNFREE is committed to the research, development and market application of original gold leaching reagent with “low consumption and high production” as the core, and constantly innovates to meet the customers’ diversified needs, contributing its own strength to global gold mining industry.
