Consequently, none of the conventional coal cleaning, or beneficiation, methods are broadly applicable to the field of lignite beneficiation. A description is presented of new lignite beneficiation methods, which are complete departures from the prior art, based on known and proven scientific, engineering and metallurgical principles.
A froth flotation process for the beneficiation of coal, which process comprises the steps of (a) forming an aqueous slurry of coal particles, (b) adding an effective amount of a collector consisting essentially of a crude tall oil or a crude tall oil equivalent to the aqueous slurry of coal, (c) subjecting the aqueous slurry of coal containing the collector to froth flotation, and (d) separating the floated material comprising .
The beneficiation of coal promotes homogeneity in the size of pulverized coal after comminution, as well as helping with the separation of impurities that result in ash and sulfur production when coal is burned. (12) One method of beneficiation is gravity separation via the screening of coal particles through sieves of decreasing size.
A method of beneficiating coal which has noncarbonaceous impurities comprising; forming an aqueous slurry consisting of coal particles and water, cavitating the slurry with intense agitation to break the coal particles into small particles and to impregnate the particles with water and to break off noncarbonaceous impurities from the coal particles, gravitationally separating the coal particles from a .
anthracite coal exhibits a high ignition temperature, rendering explosion vents or a deluge system unnecessary. Carrier has developed a number of thermal coal drying systems for several types of coals and process applications. Some of these include: † Anthracite coal for additives in the steel making industry † Beneficiation of PRB coals
