Insitu leaching (ISL), also called insitu recovery (ISR) or solution mining, is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit, in situ leach works by artificially dissolving minerals occurring naturally in a solid state. For recovery of material occurring naturally in solution, see: Brine mining.
Silver mining in the United States began on a major scale with the discovery of the Comstock Lode in Nevada in 1858. The industry suffered greatly from the demonetization of silver in 1873 by the Coinage Act of 1873, known pejoratively as the "Crime of 73", but silver mining continues today.
Mining silver, or any mineral in general, can greatly impact our environment. For one, it causes lots of erosion. It also contaminates groundwater, soil and surface water by using chemicals from the mining process. Plus, mining contributes to the formation of sinkholes and loss of biodiversity.
The four openpits and other plant facilities are situated on 19,000 acres. Mining affected areas of the facility total 3,900 acres. Copperbearing solutions from the dump leach and rubble areas are collected and pumped to the solvent extraction plant where the copper in solution is concentrated over 30 times before being pumped to the tank house.
The resulting pregnant strip solution proceeds to the EW circuit for gold and silver recovery while the barren carbon travels to the reactivation kiln. A combined gold and silver sludge from the EW cells is filtered, dried, retorted to remove the mercury from the sludge, and smelted to produce bullion bars.
