Coal Beneficiation Process DiagramCoal mining World Coal Association

Many breakers and washeries efficiently handle the coarser sizes but waste the coal fin This problem is assuming major importance due to the increase in the amount of coal fines being produced by the mechanization of coal mining Flotation offers a very satisfactory low cost method for recovering a fine low ash clean coal product at a profitThe coal is then loaded on to large trucks or conveyors for transport to either the coal preparation plant or direct to where it will be used Mine rehabilitation Coal mining is only a temporary use of land so it is vital that rehabilitation of land takes place once mining operations have stopped

Coal Simple English Wikipedia the free encyclopediaCoal formation Energy Education

Coal is a hard rock which can be burned as a solid fossil fuelIt is mostly carbon but also contains hydrogen sulphur oxygen and nitrogenIt is a sedimentary rock formed from peat by the pressure of rocks laid down later on top Peat and therefore coal is formed from the remains of plants which lived millions of years ago in tropical wetlands such as those of the late Carboniferous Process The process that creates coal varies slightly in different areas depending on the plants and conditions that are present but the overall process is similar There are two main phases in coal formation peatification and coalification Bacterial activity is the main process that creates the peat during peatification
