Leaching Process
Another process in which copper and uranium are recovered is via a process called InSitu Leaching. Tank Leaching and Vat Leaching are processes wherein the ores are placed in large tanks (or vats) which contain leaching solutions. They can be used to extract metals from their ores. Thus, the leaching process offers a wide range of variations ...
