The Four Main Methods of Mining - OreFlow

2019-12-4  Strip mining – Strip mining is the most common surface mining method used to mine coal and lignite. The process is done by removing a strip of overburden before mining a seam of mineral. Strip mining is done only when the ore body is in close proximity to the surface. Open-pit mining – Open-pit mining is the method in which minerals or ...

What are the different methods of mineral extraction?

2020-5-7  What are the different methods of mineral extraction? 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. Click to see complete answer.

Strip mining. Strip mining is the activity of removing a layer of earth to access the minerals that are in shallow deposits and continuing to do the same in adjacent areas without digging deeper vertically. Strip mining is best suited for shallow and horizontally located deposits. Strip mining activities often impacts a broader surface area.

Mining Methods. There are four key stages of work involved in mining for minerals. These include: 3415, 3416 Prospecting – The purpose of this stage is to identify areas that are likely to contain mineral deposits. The work includes geological, geochemical and geophysical surveys (e.g. seismic surveying), aerial surveys, including the taking of samples by low-impact mechanical methods.

Materials slowly accumulate via water and/or wind action and turn in a big deposit known as placer. Then the placer is collected, rinsed, and sluiced to pull out the desired minerals. This is one of the simpler methods of mining.
