The Four Main Methods of Mining - OreFlow

2019-12-4  In-situ mining (also called in-situ leaching or recovery) is a mining method that’s used to obtain minerals like uranium and copper through drilled boreholes into a deposit. In-situ mining works by dissolving naturally occurring minerals that are in a solid state. A leaching solution is pumped into the boreholes where it makes contact with the ore.

What is the difference between opencast

Open cast mining is the removal of rocks or sediments that contains minerals, with economically important elements. The advantages of open cast mining: • More cost effective, than shaft mining. • The working conditions are safe for miners, there is no risk of toxic gases or cave ins. • Trucks and mining machinery can move around freely.
