摘要： A process for the wet concentration and cleaning of fine coal is provided which comprises the steps of desliming and thickening a dilute slurry of fine coal and contaminant particles having a size of less than about 10 mm by introducing the same to a hydrocyclone separator to retain a slurry of particles having a size greater than about 0.1 mm, wet concentrating the last-named slurry and removing the heavier contaminant particles by introducing it to an autogenous dense medium separation vessel having a manifold for injecting water at an intermediate level and controlling the underflow of heavier than coal particles to maintain a fluidized bed of heavier particles and causing a slurry of the lighter coal particles to overflow, and concentrating and dewatering the overflow by means of a static or vibratory sizing screen.

摘要： The corrosion of aqueous heavy pulps which contain ferrosilicon with between 8 and 20 weight % of silicon as a heavy medium and are used in the heavy media separation of minerals is inhibited. To this end, the heavy pulp is used in admixture with between 0.1 and 0.8 weight % of a carboxy-alkane-phosphonic acid of the following formulae: ##STR1## in which R stands for hydrogen or alkyl having from 1 to 4 carbon atoms, or ##STR2##

摘要： Copper is recovered from an aqueous pulp of an ore containing both sulfide minerals and oxidized minerals by continuously monitoring the EMF of the pulp and adding a water-soluble sulfide to the pulp in an amount from 0.05 to 7 pounds of contained sulfur per ton of ore whenever and for so long as the pump EMF is above about -30 millivolts with reference to a standard silver-silver chloride electrode, and discontinuing such addition whenever such EMF in less than about -30 millivolts. Thereafter the pulp is subjected to a froth flotation operation in the presence of a collector for copper sulfide minerals to produce a concentrate containing most of the sulfide minerals and a substantial part of the oxidized minerals of the ore.

摘要： Two open-end tubes are vertically immersed, open-end down at substantially the same level, one near the place of entrance of a liquid in process in a series of treating vessels and the other near the outlet of the liquid whereby densities of the liquid at the respective locations are measured by means of a suitable pneumatic assembly, the density values are translated to and recorded as a pneumatic pressure differential and the pneumatic pressure differential is either (1) automatically converted to and recorded in meaningful values and the indicated adjustments manually made to restore and tend to maintain the optimum density differential, or (2) directed to an optimizer whereby optimum adjustments are automatically made to restore and tend to maintain a maximum density differential. Where a fluctuating level of liquid exists, two probes immersed at different depths to define a fixed stratum may be used in cooperation to obtain one density value.

摘要： A method and apparatus for separating discrete solid articles according to their density is described. A fluid is placed in a vessel, and discrete solid articles having various densities are placed therein. The density of the fluid is altered to a value which will cause separation of the solid articles due to differences in buoyancy. The density of the fluid separating medium is preferably altered by injection of small gas bubbles or other fluid substances having a density differing from the first fluid placed in the vessel.

摘要： This float-sink apparatus utilizes media of two different densities in which the liquid level in the higher density media sump is automatically sensed and controlled through the addition of media makeup to the sump when the level is low. The change in density is sensed by a density sensor which controls the addition of water in the flow line between the high density sump and the high density separator. The low density system is similarly controlled, except that the level sensor controls the diversion of high density media from a drain screen into the low density sump, rather than controlling the addition of media makeup to the low density sump. The wash circuit of the system directs washed media makeup from both the high density separated product and the low density separated product to a magnetic separator and then to a densifier which acts at a constant rate to feed all of the washed and separated media makeup directly into the high density media sump.
摘要翻译：该浮子沉没装置利用两种不同密度的介质，其中当水平较低时，通过向贮槽添加介质，自动地感测和控制较高密度的介质池中的液位。密度变化由密度传感器感测到，该密度传感器控制在高密度贮槽和高密度分离器之间的流动管线中添加水。类似地控制低密度系统，除了水位传感器控制将高密度介质从排水筛转移到低密度贮槽中，而不是控制向低密度贮槽添加介质组成。系统的洗涤回路将从高密度分离产物和低密度分离产物的洗涤介质组成引导到磁性分离器，然后引导到致密剂，其以恒定速率起作用，直接将所有洗涤和分离的培养基补充进料高密度介质池。
