Insitu underground gold leaching Hydrometallurgy,There is a method of gold mining by underground leaching Especially in areas with a limited amount of water Who has experience with Insitu recovery or ISR It applied particularly in hard rock ore bodies involves drilling rock fracturing and leaching of value metals away from gangue while the rock remains in place
Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer miningsuch as simple gold panning and sluicing, resulting in direct recovery of small gold nuggets and flakes. Placer m
For cyanide leaching gold, depending on the level of gold content in the material to be leached, its concentration is generally 25%-33%. If the carbon adsorption gold extraction process is used, in order to suspend the carbon, the slurry concentration should be increased to 40%-50%. (Heap leaching method for gold extraction) 2.Temperature
