Filed:

Jun 20, 2007

Appl. No.:

11/765868

Inventors:

David H Creasey - Boerne TX, US

Assignee:

Phitex, L.L.L.P. - Cocoa FL

International Classification:

C09K 3/00

US Classification:

25218311, 25218314

Abstract:

A process and composition of matter for the recovery of metal from a metal-laden ore, soil or rock is provided. A liquid, non-toxic, low pH acidic composition is used as a chelating agent that extracts the metal into a pregnant liquid solution. The pregnant solution is treated by known conventional means, such as filtration, centrifuging, or electrolysis to remove the extracted metals. The low pH, acidic composition (LpHAC) does not have any known toxicity to man or the environment and performs as an ideal fluidized reaction metal extractant. As a metal extracting agent, it effectively and efficiently extracts gold and other metals from ore laden soil or rock with no environmental and negative health impact.

US Classification:

75739, 75741, 75743, 75744, 25218311, 25218314

Abstract:

An improved process and composition for the extraction of metal from a metal-laden ore, soil or rock is provided. A liquid, three-component aqueous lixiviant comprises water, an alkali metal salt and a low pH acidic composition. A four-component aqueous lixiviant comprises water, a low pH acidic composition, an alkali metal salt and an acid having a pH value less than 2. Both lixiviant compositions are efficient for extracting metal into a pregnant liquid solution. The pregnant solution is treated by known conventional means, such as filtration, centrifuging or electrolysis to remove the extracted metals. The three-component and four-component aqueous lixiviants of the present invention are non-toxic, meaning, not an irritant or deleterious to humans or the environment and perform, as well as, or better than known toxic cyanide lixiviants. The aqueous lixiviants of the present invention effectively and efficiently extract gold, silver, platinum and other metals from ore laden soil or rock with efficiencies greater than 90%.

Abstract:

A composition of matter and the method of making that provide a low pH acidic composition that is useful for destroying microorganisms that are undesirable and useful for destroying or reducing melanoma on human skin. The composition and method include a strong, low pH acid combined with distilled water and urea or an ammonium compound, such as ammonium sulfate or other metallic sulfates, including but not limited to, sodium sulfate, magnesium sulfate, zinc sulfate, manganese sulfate, and copper sulfate, under at least 15 psi pressure in pressurized container, all of which is heated to approximately 800 F. or more for at least 3 hours. The final cooled mixture is stabilized with 10 to 15 percent of the original mixture. The resultant composition is useful for preserving food, such as fresh fish, and for skin treatment of melanoma and as bactericides, fungicides, or viricides.

Assignee:

Contact Marketing Solutions, LLS - Danbury CT

International Classification:

C09K 8/74

US Classification:

507269, 1663051

Abstract:

An aqueous mixture of a non-toxic, low pH, antimicrobial, acidic composition having a pH between approximately 0. 5 and approximately 3. 5 is used in a drilling fluid and a stuck pipe additive. One embodiment of the stuck pipe additive composition includes an alkali metal halide salt in a range of approximately 10-35 weight %; a sequenching agent in a range between 2-8 weight %, a low pH, non-toxic acid composition in a range of 0. 5-20 weight percent and water in a range of 7-88. 5 weight %. As a drilling fluid, it maintains well control and removes drill cuttings from holes drilled into the earth. As a spotting fluid, it frees a stuck drill stem in the annulus of a bore hole in minutes.

US Classification:

507269, 1663051

Abstract:

An aqueous or oil-based mixture containing a non-toxic, low pH, antimicrobial, acidic composition having a pH between approximately 0. 5 and approximately 3. 5 with and without a proppant is used as a subterranean well stimulation additive. Without a proppant, the LpHAC stimulation additive is used for acidization. In another embodiment, with a proppant, the LpHAC stimulation fluid is used in hydraulic fracturing. As a well stimulation fluid, it involves the injection of specially engineered fluids and other materials into the well bore at rates that actually cause the cracking or fracturing of the reservoir formation to create fissures or cracks in the formation to increase fluid flow of underground resources from the reservoir into the well bore.
