Mineral Mining Techniques

[title]

What are the main methods of mining? | American,

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.Mining Techniques | Geology for Investors,Mining techniques can be divided into two broad categories: surface mining and subsurface mining (See Figure 1). Surface mining consists of stripping soil and vegetation away and possibly a limited amount of rock and then removing ore in large quantities.Mineral Mining, Mineral Mining Companies, Mineral Mining,,We provide latest updates in the mining industry, the information resources available helps the traders to get the info about the industry investors and others, the rich information in this site gives valuable inputs with regards to types of metals mining, minerals mining & precious stones and their properties.
