Mining | National Geographic Society

May 20, 2022The two major categories of modern mining include surface mining and underground mining. In surface mining, the ground is blasted so that ores near Earth's surface can be removed and carried to refineries to extract the minerals. Surface mining can be destructive to the surrounding landscape, leaving huge open pits behind.

The Four Main Methods of Mining - OreFlow

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.
