Disclosed is a method for removal of an unburned carbon contained in a fly ash material. The method comprises the steps of: adding water to the fly ash to prepare a fly ash slurry; shearing the fly ash slurry using an agitating blade that can rotate at a high speed to generate an active energy on the surface of an unburned carbon by the shearing force, thereby imparting lipophilicity to the unburned carbon; and adding a collecting agent and a foaming agent to the slurry containing the lipophylized unburned carbon to cause the attachment of the collecting agent to the lipophylized unburned carbon, and at the same time, causing the attachment of the unburned carbon having the collecting agent attached thereto to an air bubble to separate the unburned carbon by flotation.

Amine-aldehyde resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These resins are especially useful as froth flotation depressants in the separation of bitumen from sand and/or clay or in the beneficiation of clay (e.g., kaolin clay) from an impure clay-containing ore. The resins are also useful for treating aqueous liquid suspensions to remove solid particulates, as well as for removing metallic ions in the purification of water.

33 ACTIVATED FLOTATION CIRCUIT FOR PROCESSING COMBINED OXIDE AND SULFIDE ORES US14153931 2014-01-13 US20140197076A1 2014-07-17 William D. Simmons
A method of extracting targeted metallic minerals from ores that contain sulfide metallic minerals along with oxide minerals, carbonate minerals, silicate minerals, halide minerals or combinations thereof. In the method, an ore slurry containing the metallic mineral in oxide, carbonate, silicate or halide form is provided. The slurry is activated by adding sodium thiosulfate and sodium metabisulfite, whereby the targeted metallic mineral forms an intermediary metal complex with the sodium thiosulfate and sodium metabisulfite. One or more metal release components are introduced into the ore slurry; whereby the targeted metallic mineral is released from the intermediary metal complex to form a metal sponge. This metal sponge is then subjected to a flotation process, whereby the targeted metallic mineral is drawn out of the ore slurry and thereby extracted from the ore.

37 Process for the separation of mineral substances US319626 1981-11-09 US4406781A 1983-09-27 E. Richard Nightingale
Provided is a process and apparatus for the separation of solid mineral substances. Particular applicability is found in the separation of resins from resin-bearing coal material. The resins are effectively separated by treating the resin-bearing coal with a non-solvent liquid, e.g., water, and then subjecting the resultant slurry to centrifugal force, e.g., in a classifying cyclone separator. The step of subjecting the resin-bearing coal slurry to centrifugal force is effected concomitantly in the presence of a gas such as air. A quality resin concentrate which is usable without subsequent refining can thereby be recovered.

Undigested matte particles in autoclave leach residues containing iron oxide are separated from iron oxide by subjecting an aqueous slurry thereof to flotation without the use of a flotation reagent by bubbling air therethrough to form a froth containing said undigested matte particles which is recycled for further leaching and provide an iron oxide-containing tails which is removed and discarded.
39 Process for separating soap from black liquor US618396 1975-10-01 US4022653A 1977-05-10 Hong H. Lee
Soap is separated from spent, cellulosic pulping liquor by strenuously percolating a gaseous, aliphatic hydrocarbon through a quantity of liquor volume under such temperature and pressure conditions that an equilibrious strata of liquid phase hydrocarbon is sustained on the surface of the liquor. Following strenuous combination and agitation, the gas-liquor mixture is allowed to settle so that the entrained, gaseous hydrocarbon and coagulated soap floc gravimetrically rises to the liquor surface and stratifies with the soap layer between the residual liquor solution and a liquid phase layer of hydrocarbon. Thereafter, the liquid hydrocarbon and soap layer are decanted away from the residual liquor solution and depressurized to vaporize the hydrocarbon leaving a reservoir of isolated soap.
40 Beneficiation of sylvinite ore US30013172 1972-10-24 US3802632A 1974-04-09 DANCY W
Coarse clay-containing sylvinite having a maximum particle size of from about 3/4 inch to about 3/8 inch is divided into two portions by sizing at about 1/4 inch to about 4 mesh and the coarser fraction containing unliberated ore particles is subjected to gravity separation to reject significant amounts of clay and halite. Both the concentrate from the gravity separation which is comminuted to liberate mineral constituents and the minus 1/4 inch to 4 mesh fraction from the initial sizing are subjected to gravity beneficiation.
