摘要： A process for beneficiating oil shale is disclosed including the steps of grinding the shale to fine particles in an aqueous medium, portions of which are kerogen-rich and kerogen-poor, scrubbing the particles, conditioning using a collector and a frother, and separating using froth flotation and oil agglomeration/dewatering.

摘要： A process for beneficiating oil shale is disclosed including the steps of grinding the shale to fine particles in an aqueous medium, portions of which are kerogen-rich and kerogen-poor, scrubbing the particles, separating the particles by either selectively flocculating out a fraction, redispersing the fraction and reseparating using froth flotation, or vice versa, and oil agglomerating/dewatering the kerogen-rich fraction.

摘要： A process for grinding organic-containing mineral matter, particularly oil shale, is disclosed comprising a series of increasing finer grind-producing grinding steps, each followed by an organic beneficiation step. A portion of the organic-enhanced beneficiation product is mixed with each successive grinding step feed.

摘要： A combination of raw coal and water is introduced as a slurry into a vessel. Chemicals are introduced at a feet inlet. The mixture is reduced by interaction with a bed of agitated grinding balls. Air is introduced into the lower portion of the vessel and forced upwardly through the circuitous passages among and between the grinding balls. The rising air bubbles carry the more hydropholic product upwardly into a froth compartment of the vessel and through a discharge outlet of the vessel. Wash water is introduced into the upper portion of the vessel and descends through the froth and the ball passages carrying entrained and less hydrophobic particles into the grinding chamber. The non-floatable material flows downwardly from the grinding chamber to a refuse zone for discharge as refuse from the vessel.

摘要： The efficiency of conversion of coal in the coal-gasification process is increased by pre-treatment of the coal to increase the fluid-permeability thereof. The reagent used for increasing the coal permeability is recoverable in high yield. Pre-treatment of bituminous coal by this process makes it possible to gasify coals of this rank effectively, such coals previously having been gasifiable only at low conversion efficiencies. Pre-treatment with a permeability-enhancing reagent is also useful as a step in the process of dissolving coal.
摘要翻译： 通过预处理煤来提高煤气化过程中煤的转化效率，增加煤的流体渗透性。 用于提高渗透率的试剂可以高产率回收。 通过该方法对烟煤进行预处理使得有可能有效地气化该等级的煤，这种煤以前仅在低转化率下才可气化。 用渗透性增强剂进行预处理也可用作溶解煤的过程中的一个步骤。
