Ore processing plant means that extracts and purifies some elements in the raw ore through a series of complex ore beneficiation flow and professional beneficiation equipment. The refined concentrate powder is mainly used in metallurgy and industry base.
Magnetic separation makes use of magnetic differences between minerals to separate material, which occupies a very important position in iron ore separation field. Magnetic separating plant has the advantages of energy saving, high efficiency and high

Coal mining and transportation US Energy Mining coal Coal miners use large machines to remove coal from the earth Many US coal deposits called coal beds or seams are near the earths surface while others are deep mining methods allow coal miners to easily reach most of the nations coal reserves and to produce about three times more coal in one hour than in 1978
Coal mining extraction of coal deposits from the surface of Earth and from underground Coal is the most abundant fossil fuel on Earth Its predominant use has always been for producing heat energy It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th
Surface Coal Mining and Reclamation Surface coal mining involves disturbing overlying rock layers overburden to expose and extract coal reserves using the area mining method wherein the overburden above the uppermost coal seam and the innerburden between the lower coal seams are removed in parallel strips pits across the coalfield until the area is mined
Types of surface mining Strip mining This process involves the method of extracting the mineral by removing soil and rock which are deposited on the and Lignite are the two principle minerals that are extracted through this method This kind of mining can be done when the mineral to be extracted almost near to the
