摘要： A process of selectively agglomerating coal in an aqueous environment while leaving the mineral matter dispersed has been developed. This process is autogenous for hydrophobic particles in that neither an agglomerating agent nor an electrolytic coagulant is needed. It is based on the finding that hydrophobic particles are pushed against each other by the surrounding water structure. This process, which is referred to as selective hydrophobic coagulation, is driven by the so-called hydrophobic interaction energy, which is not included in the classical DLVO theory describing the stability of lyophobic suspensions. The relatively small coagula formed by the selective hydrophobic coagulation process can be readily separated from the dispersed mineral matter by several different techniques such as screening, elutriation, sedimentation and froth flotation.

摘要： Fine coals are dewatered in an energy efficient process in which a non-polar liquid or a mixture of different hydrophobic liquids are used to displace the water from the coal surface. This process works with higher rank coals that are naturally hydrophobic so that the coal surface from which the water is displaced has a stronger affinity for the hydrophobic liquid than the water. Thermodynamically, this process is spontaneous and, hence, requires no energy. The only energy required for this process is to recover the spent hydrophobic liquid(s) for recycling purposes. The hydrophobic liquids are recovered in gaseous form either by lowering the pressure or by heating, and coverted back to liquid form for re-use. The most economical reagents that can be used for this purpose include propane, butane, pentane, and ethane. Carbon dioxide can also be used for the dewatering process described in the present invention. The process of dewatering by displacement is capable of achieving the same level of moisture reduction as thermal drying but at substantially lower energy costs.
摘要翻译：精细煤在能量有效的过程中脱水，其中使用非极性液体或不同疏水性液体的混合物来从煤表面置换水。该方法与具有天然疏水性的较高级煤一起工作，使得水被排出的煤表面与疏水性液体相比具有比水更强的亲和性。在热力学上，这个过程是自发的，因此不需要能量。该方法所需的唯一能量是回收用于回收目的的废疏水性液体。疏水性液体通过降低压力或加热回收成气态，并被覆盖回液体形式以供再利用。可用于此目的的最经济的试剂包括丙烷，丁烷，戊烷和乙烷。二氧化碳也可用于本发明所述的脱水方法。通过置换脱水的过程能够实现与热干燥相同的水分降低水平，但是以显着更低的能量成本。

摘要： A method and apparatus are disclosed for the microbubble flotation separation of very fine and coarse particles, especially coal and minerals, so as to produce high purity and high recovery efficiency. This is accomplished through the use of a flotation column, microbubbles, recycling of the flotation pulp, and countercurrent wash water to gently wash the froth. Also disclosed are unique processes and apparatus for generating microbubbles for flotation in a highly efficient and inexpensive manner using either a porous tube or in-line static generators.

摘要： Mineral content in processed ore and coal content in coal slurries are determined using a video system. A video image is taken of a sample, the video image is digitized, and gray levels are assigned to points or areas on the video image. The distribution of the gray levels for the image provides an indication of the purity of the minerals in the ore sample. The mean gray level for the image provides an indication of the mineral content of interest in the sample. The video system should be calibrated using ores that normally occur in the process environment and using samples of controlled moisture content. The video system has particular utility in determining phosphate content and calcium ratio in phosphate ores.

摘要： A flotation separation system is provided for partitioning a slurry that includes a hydrophobic species which can adhere to gas bubbles formed in the slurry. The flotation separation system comprises a flotation separation cell that includes a sparger unit and a separation tank. The sparger unit has a slurry inlet for receiving slurry and a gas inlet to receive gas with at least enough pressure to allow bubbles to form in the slurry within the sparger unit. The sparger unit includes a sparging mechanism constructed to disperse gas bubbles within the slurry. The sparging mechanism sparges the gas bubbles to form a bubble dispersion so as to cause adhesion of the hydrophobic species to the gas bubbles substantially within the sparger unit while causing a pressure drop of about 10 psig or less across the sparging mechanism. The sparger unit includes a slurry outlet to discharge the slurry and the bubble dispersion into the separation tank.
