01-06-2020· Two types of leaching tests were employed in this study, i.e., baseline and leaching kinetic tests. While the baseline test consisted of keeping the waste materials entirely under water for periods of at least six months, the kinetic test involved exposure of the waste materials to a weekly cycle of dry air followed by humid air for up to 20 weeks.
Leaching - Mining Fundamentals
The two main types of leaching are heap and insitu leaching. Heap Leaching Heap leaching is also known as acid leaching. This method is most effective for the extraction of metals from difficult ores, and is one of the most tried and tested methods. The pre-processing of ore before leaching involves the grinding and roasting of the ore.
