The Four Main Methods of Mining OreFlow

2019-12-4  Surface mining is a method of mining that involves removing the soil and the overlying rock on top of the mineral deposit. This method of mining gained popularity since the start of the 20th century, especially in North America where the majority of surface mining occurs. Strip mining is done only when the ore body is in close proximity to

What is mining? Mongabay

Large scale mining involves a large company with many workers. These are also localized at one or two sites. Small scale mining involves a group of traveling men, usually about 5-8, who migrate from one mining site to another. This type of mining tends to be more destructive to the environment because of the area of land covered.
