Although most of the magnetite used in densemedium coal beneficiation can be recovered by magnetic separation, there are small but significant losses. The magnetite losses can be attributed to removal in the wash wastes or uptake into fractures of the coal particles. To determine the relative significance of these mechanisms we studied the magnetic properties of two samples of uncleaned ...

Raw coal may be sold as mined or may be processed in a beneficiation/washing plant to remove noncombustible materials (up to 45% reduction in ash content) and inorganic sulfur (up to 25% reduction). Coal beneficiation is based on wet physical processes such as gravity separation and flotation. Beneficiation produces two
Dry beneficiation as a coal beneficiation process Dry beneficiation could be regarded as a partial replacement for wet beneficiation techniques or an alternative approach for recovering rejected fine coal that is created in conventional coal preparation plants in the form of underflow thickeners and slurries. The dry beneficiation of coal can be
Waste constituents of concern include radionuclides (radium, radon, thorium, and to a lesser extent lead), arsenic, copper, selenium, vanadium, molybdenum, other heavy metals, and dissolved solids. Brines, spent ion exchange resins, and chemicals used in beneficiation operations are also constituents of wastes generated during beneficiation.
