2020-7-1 There are five basic types of surface mining, including open-pit mining, strip mining, dredging, mountaintop removal, and high wall mining. All of these methods remove the waste material or the overburden, which is above the desired resource. Often, surface mining is preferred over underground mining, or subsurface mining, for numerous reasons.

MetalsMining; by Prithvi March 9, 2018 March 11, Compared to other mining methods, room-and-pillar mining is a low-cost method with a low recovery rate (since some ore is left behind in pillars). Yet, the method causes very little dilution as the contact between ore and waste is limited due to the waste being
get price2020-9-1 There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
