Jul 26, 2021 Clean Mining, part of the Clean Earth Technologies Group, has been working to transform gold production worldwide with a new mineral processing technology that eliminates cyanide in the gold recovery process. This solution replaces toxic cyanide with a non-toxic gold recovery agent, benefiting both human health and the health of the environment. Microbial destruction of cyanide and its related compounds is one of the most important biotechnologies to emerge in the last two decades for treating process and tailings solutions at precious metals mining operations. Hundreds of plant and microbial species (bacteria, fungi and algae) can detoxify

of high-grade ore and can be acquired at a cost of $10 per ton of ore (cost of mining ore at site). A sodium cyanide process is used to extract the gold from the ore, and various other processing techniques are used to produce 99.9% pure gold bullion from the ore. The results of the feasibility study show that the ore can be processed by agitation China constituted around 13% share of the total gold production in the world in 2018. The country has been promoting mining activities by allowing foreign investments in the mining sector over the last few years. Sodium cyanide is widely used in gold mining, due to its high affinity toward metals.

May 16, 2017 Hydrogen cyanide and cyanides are used in various industries including the mining of silver and gold. Furthermore, they are used in plastic production of all kinds of dyes as well as in chemical laboratories (Dzombak et al. 2016). The sources of environmental pollution are, among other mines, metallurgical plants and exhaust gas from vehicles. Sodium cyanide cost contributes an estimated 5% towards cash costs for most mining companies, and it is tied to long-term profitability. As a result, a reliable, low-cost sodium cyanide supply partner is an important part of any gold mining company.
