TENORM Copper Mining and Production Wastes Radiation Alternative Lixiviants to Cyanide for Leaching Gold Ores

Leaching There are two main leaching methods heap leaching and in situ leaching Heap leaching is the most common method used in the US When processing copper through heap leaching vast quantities of ore and overburden overburdenSoil and rocks that have been moved out of the way to get to ore are called overburden In areas where there Hence the application of thiourea to gold leaching may lie in improving other alternative lixiviant processes where only small dosages are used 4 Halide Leaching Chlorine bromine and iodine are well known lixiviants for leaching gold as reviewed by Tran et al Chlorination was applied extensively in the late 19th century before
