enviroleach technologies, inc.

EnviroLeach’s objective is to become a leading producer of precious metals using its proprietary and Environmentally Friendly metallurgical processes. 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. The EnviroLeach process is similar to a cyanide circuit but in-fact much safer and simpler. It involves the dissolution of the precious metals into the aqueous solution followed by extraction using conventional methods such as electrowinning, carbon absorption or precipitation. The operation is simple and does not require complex process circuits, intensive gas monitoring or detoxification systems. Some of the operational benefits include: • Faster & more effective leach kinetics • Environmentally friendly & safe • Broad applicability spectrum • Near neutral pH • Operates at ambient temperature • No off-gas or detox controls required • Improved sustainability via the reusability of solution • Simplified recovery of metals from solution
