EnviroLeach Technologies Inc. has developed a unique, cost-effective and environmentally friendly alternative to cyanide for the hydrometallurgical extraction of precious metals for the mining sector. The patent-pending EnviroLeach process is safe, eco-friendly, and provides faster leach kinetics than cyanide on most ores, concentrates and tailings.
Mitigating the environmental impact of resource extraction is a responsibility that the mining industry takes very seriously and is a key component of maintaining the privilege to operate. The mining industry strives to practice high environmental standards with a commitment to sustainable development and production. The EnviroLeach process may assist the industry with meeting this commitment.nbsp.
Eco-goldex claims that this is the most effective and eco-friendly gold stripping reagent in E-waste material recycling available in the market. O Series Reagent is effective for normal gold ores leaching and an alternative of sodium cyanide in gold extraction. This reagent is idea for oxide, semi-oxide ores and easy mill sulfide gold ores.
The hydrometallurgical extraction of gold from ores, concentrates, and tailings in a cost effective and environmentally safe manner offers an interesting challenge.nbspnbspConventional gold mining operations rely heavily on cyanide leaching as the predominant method for recovering gold from ores and concentrates. Cyanide has been the leach reagent of choice in gold mining because of its high gold recoveries, robustness and relatively low cost. As a result, over 85 of all gold extracted worldwide is produced by hydrometallurgical extraction with the use of cyanide.
The gold mining sector uses approximately 66,000 tons of sodium cyanide annually worldwide.nbspThe use and subsequent disposal of cyanide, present significant safety and environmental challenges.nbspAs a result, the safety, environmental and associated permitting issues have been a critical driver for the industry to evaluate effective alternatives.
These alternative lixiviants have to offer comparable leach kinetics, be environmentally friendly and cost effective. Some of the experimental alternative lixiviants have included thiosulfate, thiocyanate, ammonia, bromine, chlorine, bisulfites, thiourea and others.nbspSome of these chemicals offer comparable leach kinetics under certain conditions, but for a variety of reasons, none are reported to be an effective alternative to cyanide.nbspnbspnbsp.
Cyanide and cyanide gas are both toxic and care has to be taken during ore processing to avoid exposure for workers.nbspSolutions containing cyanide have to be carefully monitored and managed to prevent the formation of deadly cyanide gas.nbspIn addition, there are significant costs associated with destruction of cyanide in the tailings streams and final disposal.nbspnbsp.
Internationally, several countries, like the Czech Republic, Greece, Turkey, Germany, Hungary, Costa Rica, Argentina, Ecuador, and some states of the United States e.g. Montana have banned cyanide leach technology in gold and silver mining. Therefore an environmental friendly alternative is crucial for the continued development of the mining sector.
The EnviroLeach reagent is ideally suited for the leaching of gold in an agitated or vat leach type process. This includes the treatment of whole ores, gravity concentrates, and flotation concentrates. This segment of the market represents the majority of the worldwide gold produced.
