Specification and testing of magnetite for exploration, quality control and in-plant check purposes is discussed. The disposition of Australian magnetite deposits in relation to the main coal producing areas is examined, and comments are made on the economics of mining, milling and beneficiating magnetite for coal preparation uses alone.
magnetite and coal mining Ernest Henry Mining: Magnetite Processing. Magnetite (Fe3O4), like hematite (Fe2O3), is a form of iron ore. It is a benign and highly magnetic substance used primarily in steel manufacturing and coal Get price
Conveyors or cars (railway wagons) transport the coal to vertical shafts for removal from the mine. After the coal is brought up to the surface by conveyors, it undergoes a process that removes sand and mud by immersing the coal in a solution of water and tiny magnetite particles. The different elements separate naturally. The coal floats while
new dense-medium cyclone plant at Tertre in Belgium to process 10 x 0 mm raw coal. The plant was unique in that the feed to the plant was not de-slimed before processing. The raw coal was mixed with magnetite and gravity-fed to two 500 mm diameter (D) cyclones at a feed pressure of 9D. The minus 0.75 mm coal in the feed drained through
outside the mining area for placement and storage. In the Midwest, where the surface topography and coal seams are generally flat, it is common to employ area strip mining in which the fragmented overburden is placed directly by large draglines in the space created where coal has been mined ().In some situations in the eastern United States, a coal seam occurring near the top of mountains is

Coal mining Coal mining Prospecting and exploration: The fundamental objective of coal prospecting is to discover coal resources through a search. In areas where coal mining has not been previously practiced, the search process should result in obtaining coal samples that give reasonable evidence of the existence of a coal seam. Once a seam has been discovered, considerable further work is
Stockpiles of magnetite typically occur as a result of mining operations discarding mined magnetite ore when mining for other commodities. Mineralogy: The study of the chemistry and physical properties of ore and gangue minerals within mineral deposits. Mini-Mills: Steel production plants that rely on steel scrap as a base material rather than
When coal from the mine is pulverized and added to the slurry, the heavier waste materials, such as rock particles, will sink and separate from the lighter coal. The heavy impurities are then siphoned from the bottom of the slurry and the light coal is skimmed off the top. Using magnets, magnetite can be easily recovered from the waste and coal
