CHAPTER V MINING METHODS AND COAL PROCESSING

Underground mining methods are employed when the depth of the deposit, the stripping ratio of overburden to ore (coal or stone), or both become excessive for surface exploitation (Hartman and Mutmansky, 2002). Underground mining method selection is one of the most important decisions that mining engineers have to make.

Introduction to Mineral Processing cpchem

Introduction to Mineral Processing. Froth Flotation Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer

1.1 PHASES OF A MINING PROJECT Home ELAW

In underground mining, a minimal amount of overburden is removed to gain access to the ore deposit. Access to this ore deposit is gained by tunnels or shafts. Tunnels or shafts lead to a more horizontal network of underground tunnels that directly access the ore. In an underground mining method called stoping or block caving, sections

Mineral Processing Introduction MetSolve Labs

2.0 Processing Approach and Method In broader terms, mineral processing consists of two functions. Firstly, it involves the preparation and liberation, of the valuable minerals from waste minerals and secondly, the separation these values into two or more products, called concentrates. The term separation in this case is synonymous with

3 Technologies in Exploration, Mining, and Processing

Underground metal mining methods may be unsupported, supported, and caving methods, and there are numerous variations of each. Open stopes, room and pillar, and sublevel stoping methods are the most common unsupported methods; cut and fill stoping when the fill is often waste from the mine and mill tailings is the most common method of supported underground mining ( Figure 3 6 ).

The separation of mineral from gangue is called mineral processing. Often times, inefficient processing methods can produce gangue that still holds an ample amount of valuable minerals. As values of minerals increase, it can even be profitable to reprocess gangue to extract additional minerals that may have been missed during the first processing.
