1	Mineral beneficiation by decompression scalping	US39695273	1973-09-13	US3881660A	1975-05-06	RIBAS ROGER S
Certain minerals, particularly weathered phosphate pebble, are treated to remove significant quantities of impurities by pressurizing a slurry thereof to about 25-100 psig, preferably 30-60 psig for weathered phosphate pebble, and passing the pressurized slurry through a nozzle to the atmosphere to provide sudden release of pressure. Weathered and other encrusted minerals treated in this manner are beneficiated by the dissolution and particularly by the erosion of impurities primarily encrusted on the mineral. The erosion and collapse of the crust is believed to be caused at least partly by the sudden flow of water held in the pores of the crust.

3	Method and apparatus for treating solid municipal refuse and other cellulose containing material	US28605	1979-04-09	US4235707A	1980-11-25	Jerry A. Burke, Jr.
Solid Municipal Waste is loaded, or loaded and compacted, into a pressure vessel which has means for very fast opening for discharging the contents. The pressure vessel is pressurized, with steam, or a compressed gas such as compressed air. The pressure vessel can be fitted with a breech and a quick release muzzle cover and at the discharge end (muzzle) thereof is fitted with an orifice whose purpose is to promote a powerful turbulence and shock wave, through which the exiting solid material must pass to maintain pressure within the vessel during discharge, and to control the rate of discharge. The disruptive forces produced at the orifice, which can be either a sub-sonic, sonic, or supersonic flow orifice, are a function of the strength of the shock wave or the turbulence. The discharged material is then gravity separated in the wet or dry conditions and the separated materials are then employed in additional processes, or employed as landfill depending on its chemical and physical properties.
4	Recovering valuable mined materials from aqueous wastes	US13479999	2012-05-24	US09555418B2	2017-01-31	David S. Soane; Nathan Ashcraft; Phyo Kyaw
Disclosed herein are systems and methods for recovering a target material from an aqueous stream. The target material can be a natively hydrophobic target material, such as a hydrocarbon material, such as coal. The target material can also have a surface modification that renders it hydrophobic. Systems for recovering the target material can comprise an extractant formulation comprising a light hydrocarbon solvent and a high molecular weight hydrophobic polymer, wherein the extractant formulation is mixable with the aqueous stream in a mixer to form an admixed solution having a hydrophobic portion and an aqueous portion, with the target material partitioning to the hydrophobic portion; a separator for isolating the hydrophobic portion from the aqueous portion; and a collector to which the hydrophobic portion is directed, wherein the target material is recovered from the hydrophobic portion.

6	Method and apparatus for treatment of foliated metallic bearing materials	US35993273	1973-05-14	US3888425A	1975-06-10	COLLINS WILLIAM O
The method of this invention includes the steps of heating and drying foliated metallic bearing materials; classifying the materials into selected size groups by permitting certain of the materials to pass through screens having preselected mesh sizes; selecting certain of the groups and blasting the same at substantially high velocity into a chamber to fracture the foliant matrix of the foliated metallic bearing material, by impinging the sides of the chamber; and separating metallic material from the foliant matrix. The apparatus for treating foliated metallic bearing materials includes the combination of a material reservoir, a blast gun assembly, and a fracture chamber assembly, the blast gun assembly being in communication with the reservoir and in communication with a remote source of substantially hot, dry air under pressure. The blast gun comprises a material chamber issuing into a blast chamber. The material is communicatingly connected to the reservoir by a conduit, and the blast chamber is connected to a remote source of air under pressure. The material is drawn from the reservoir into the material chamber in response to air under pressure in the blast chamber, and is carried by the air under pressure out of the blast chamber. The fracture chamber comprises a top wall, a bottom wall and a pair of opposing side walls, and is disposed distally from the gun assembly. The gun assembly is operable to discharge the material at an angle into one end of the fracture chamber assembly, wherein the fracture assembly is electrically conducting to ground potential. The blast gun assembly is electrically insulated from ground potential.
