Hydrometallurgy Wikipedia
The five basic leaching reactor configurations are insitu, heap, vat, tank and autoclave. Insitu leaching Edit. Insitu leaching is also called "solution mining." The process initially involves drilling of holes into the ore deposit. Explosives or hydraulic fracturing are used to create open pathways within the deposit for solution to penetrate into. Leaching solution is pumped into the deposit where it makes contact with .
