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 ...

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.

What are the methods to conserve mineral resources

• Mineral resources may also be conserved through recycling. A good example is recycling of scrap metal. • One should make use of new technological methods of mining. Training of miners can be very helpful in conserving mineral resources by ensuring minimal wastage during the mining. For e.g. minerals include iron, oil, copper, salt, gold ...

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.
