Process for the separation of rock refuse and coal

A process for separating a coal containing rock material into a first rock fraction that is rich in coal and into a second rock fraction that is poor in coal, which comprises mixing a starting material consisting essentially of coal-containing rock that contains not more than 50% by weight coal, said starting material having a maximum particle size of 50 mm, and at least 7% by weight of said starting material comprises rock particles having a maximum particle size of 0.5 mm, with a suspension having a preadjusted density, the solids content of said suspension originating entirely from the starting material, introducing the resulting mixture into a hydrocyclone, passing the material obtained from the hydrocyclone through a sieve while separating coal rich and coal poor fractions, respectively, adjusting the suspension flowing through the sieve to have a preselected density

Coal Density an overview ScienceDirect Topics

Eq. (8.6) shows that depending upon the organic and inorganic content of the coal rock, the rock density could vary substantially. In lack of the laboratory measurements for a given coal rock, the organic and ash densities are assumed 1.25 and 2.55 g/cm 3, respectively. These numbers allude that for a high-rank coal, being denser in essence, with a low ash content, the density might be lower than a low-rank coal with a vast presence of ash inside the coal rock.

Coal Density an overview ScienceDirect Topics

Coal density is among the important parameters for reservoir engineering purposes and is inserted as an input property in simulation studies. Coal density is typically less than that of conventional reservoirs and differs from seam to seam based on the given coal rank and purity [2].The bulk density of a coal consists of the matrix and the void space, with the latter being expectedly filled

Float-Sink (Washability) Test, Coal Analysis, Kentucky

2020-7-27 · Because coal is less dense than most rocks and minerals (such as pyrite), it floats in liquids of equal or greater density than the coal; rock and pyrite sink. The amount of material floating is skimmed from the top of the test container, dried, and weighed as the float fraction at that liquid’s density.
