Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.
Mining is the extraction of minerals and elements of economic interest from the earth's surface. As the demand for natural resources increases, the amount of material in mineral deposits decreases.

One of the simplest types of mining is gold panning. Gold is heavier than river sand and sinks to the bottom if you rinse it with water. Shaft mining is very dangerous. Men dig a mine shaft vertically into the earth until they meet a seam a place rich in mineral deposits. Then, the miners dig horizontal shafts to dig out the minerals in the seam.
Surface mining can be used when the coal is buried less than 200 feet underground. In surface mining, giant machines remove the top-soil and layers of rock to expose large beds of coal. Once the mining is finished, the dirt and rock are returned to the pit, the topsoil is replaced, and the area is replanted.
Open Pit Mining is an excavation carried out on the surface of land that is intended to take the materials in the ore minerals in the soil surface. The main objective of the mining activities are taking deposits of parent rock, making it easy to be transported and processed within the next process further.

Mining Process Mineralogy Process mineralogy focuses on the relationships between ore and gangue minerals. The data generated from such studies characterizes the mineralogy and deportment (texture) of the various mineral phases in the ore to optimize recovery and selectivity and predict environmental sensitivities.
Mineral exploration is the process of finding ores (commercially viable concentrations of minerals) to mine. Mineral exploration is a much more intensive, organized and professional form of mineral prospecting and, though it frequently uses the services of prospecting, the process of mineral exploration on the whole is much more involved.
