Answer:
There are four main methods of mining: underground, surface, placer and in-situ
Explanation:
1.Underground Mining:- Relatively costly and frequently used to get to deeper deposits, underground mining involves digging down into the earth and creating tunnels and shafts that reach the deposits of resources.
2.Surface mining involves removal of plant life, soil and potentially bedrock to be able to access resource deposits. It is normally used for fairly shallow, non-precious deposits. The two foremost kinds of surface mining are open-pit mining and strip mining.
3.Placer Mining:-- Normally formed by weathering via water and/or wind action, placers are unconsolidated deposits of resources. Placer mining is generally done in riverbeds, sands or other sedimentary environments and involves sifting valuable materials from sediments. Famously, "panning for gold" can be part of the placer mining process.
4.In-Situ Mining
In-Situ MiningAlso referred to as solution mining, in-situ mining does not involve removing intact ore from beneath the earth's surface. Instead, it involves pumping chemicals underground to dissolve resource-containing ore and then pumping what is known as the "pregnant solution" back up to the surface, where it can be processed to recover minerals. This technique is mainly used in uranium mining.
