First, to access the actual seams or veins of ore, the top layers of rock or overburden must be removed. Once the overburden has been removed, the seams can be extracted. When extracting the seams, there is additional waste rock that must be separated from the ore. This additional waste rock is called gangue.

Four main methods of mining are available: underground, open surface (pit), placer and in-situ mining. Underground mines are more expensive and often used to reach deposits that are deeper. Surface mines are usually used for deposits that are shallower and less valuable. Placer mining is used in river channels, beach sands, or other ...

Coal mining - Coal preparation: As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions. In addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create …
2. Flotation Process Method. The flotation process can effectively remove iron, titanium and carbon impurities in kaolin, and realize the recycling and reuse of low-grade kaolin resources such as coal-measure kaolin. Kaolin clay particles are finer and more difficult to float than gangue minerals. Therefore, the kaolin flotation purification ...

Gardinier engineers were able to achieve a phosphatic clay output of 15.8% solids for a 0.8-lb consumption of flocculant per ton of (dry) phosphatic clays. When combined with tailings at a 1:1 ratio, this produced a mixture with 27.7% total solids. The water recovered, in-plant, from the feed amounted to 87.1%.

The kaolinite dry mining process is a simple and economical process. The ore is crushed to 25.4mm by a hammer crusher and fed into the cage mill to reduce the particle size to 6.35mm. The hot air in the cage mill reduces the moisture of the kaolin from about 20% to 10%. The crushed ore is further ground by a blown-type Raymond mill …
