摘要： Methods of making various capillary foams are provided. The foams can include liquid foams having a plurality of particles connected by a network of a secondary fluid at the interface between the discontinuous and continuous phase. The foams can also include solid foams where the continuous phases (bulk fluid) is removed to produce the solid foam having high overall porosities and low densities. Densities as low as 0.3 g cm−3 and porosities as high as 95% or higher can be achieved. The secondary fluid can be polymerized to further strengthen the solid foam. Methods and devices are also provided for oil recovery from water using a capillary foam. The methods can include forming a capillary foam wherein the oil is the secondary fluid, and wherein the foam can transport the oil to the surface of the water.

摘要： A process of phosphate flotation comprising: pulping phosphate ore with water to about 55% to 75% solids to produce an ore slurry; conditioning the ore slurry with a new reagent scheme to produce a conditioned slurry; subjecting the conditioned slurry to flotation to produce an underflow and an overflow; and collecting the overflow as phosphate concentrate. The new reagent scheme may comprise a combination of fatty acid, fuel oil, and fatty acid soap, and may not comprise a pH modifier. The process may also work effectively at a lower percent solids than conventional reagent schemes.

摘要： A method of processing thin stillage in an ethanol refining operation is provided. The method comprises treating thin stillage upstream of a concentration or evaporation step with an inverse emulsion comprising at least one anionic flocculant and an emulsifying agent selected from a sorbitan ester of a fatty acid, an ethoxylated sorbitan ester of a fatty acid, and combinations thereof, thereby forming treated thin stillage; clarifying the treated thin stillage via at least one of dissolved air flotation and induced air flotation, thereby forming clarified thin stillage and a float layer comprising oil and solids; separating the oil from the solids of the float layer; and recovering the oil.

摘要： A method of producing enhanced coal combustion ash for use in pozzolanic applications or cement manufacture, in which the enhanced combustion ash has lower mercury content. A slurry is formed of the combustion ash and water and is subjected to froth flotation to form a mercury-enriched ash slurry and a mercury-depleted ash slurry. The product mercury-depleted ash slurry is isolated and may optionally be dried. The combustion ash may be pulverized prior to being used to form the slurry, reducing its mean particle size. The mercury-depleted combustion ash product has reduced levels of mercury and ammonia, and reduced particle size.

摘要： An apparatus for separating a mineral from a slurry of mineral and impurities, including a fluid vessel having a first, open end and a second end and a feed well disposed near the first end. The feed well has a first, open end, for receiving the slurry, and a second end. At least one first member is received through the first ends of the vessel and the feed well for providing aerated water, creating a froth in the feed well including substantially the mineral. The mineral froth substantially separates from the impurities and floats out of the feed well towards the first end of the vessel, and a collection unit receives the mineral froth. The impurities and any remaining mineral fall toward the second end of the vessel. A measurement unit is placed within the vessel for measuring at least one of density and pressure of the fluid in the vessel. A related process includes introducing the slurry into the first, open end of the feed well, providing aerated water to the feed well and the vessel in a direction from the first ends to the second ends, respectively, creating a froth in the feed well including substantially the mineral, substantially separating the mineral froth from the impurities, collecting the mineral froth, and allowing the impurities and any un-separated mineral to fall towards the second end of the vessel. Further, the process includes measuring at least one of density and pressure of the fluid in the vessel.

摘要： A novel process for separating high viscosity bitumen from tar sand. The process includes grinding the tar sand to obtain phase disengagement of the bitumen phase from the sand phase and thereafter using flotation techniques to obtain phase separation of the bitumen phase from the sand phase. Phase disengagement is assisted by using a suitable wetting agent during the crushing step while the phase separation step is assisted by the inclusion of a promoter oil for the flotation step.
