Appl. No.:

10/406617

Inventors:

James Barthel - Arvada CO, US
Mark A. Peters - Westminster CO, US

Assignee:

MT2, LLC - Wheat Ridge CO

International Classification:

A62D 3/00

US Classification:

588407, 588412, 588315, 588318, 588256, 588901

Abstract:

A reactive coating composition and method for treating a surface including heavy metals by applying the reactive coating composition to the surface. The surface can be, for example, a paint layer containing heavy metals. The reactive coating composition includes a stabilizing agent to stabilize the heavy metal and a permeability enhancing agent to increase the permeability of the paint layer, facilitating the reaction of the heavy metal with the stabilizing agent. The structure including the treated paint layer can be left in place or can be disposed in a non-hazardous landfill.

Filed:

Feb 16, 1979

Appl. No.:

6/012782

Inventors:

Gustavo A. Meyer - Arvada CO
Mark A. Peters - Arvada CO
Helen S. Leaver - Pine CO

Assignee:

Amax Inc. - Greenwich CT

International Classification:

C01G 5308

US Classification:

423 24

Abstract:

Aqueous nickel chloride solutions containing such impurities as copper, iron, and zinc, and optionally, cobalt, and having an acid concentration ranging from about 0. 2 N to 4 N HCl together with a total chloride concentration of about 4 N to 11 N are purified of said impurities by solvent extraction with an organic extractant of essentially tributyl phosphate (TBP) dissolved in a water-immiscible organic solvent, the solvent extraction being carried out at a selected concentration of TBP and a selected volume ratio of organic to the aqueous solution effective to produce a nickel raffinate substantially impoverished in said impurities.

Appl. No.:

5/759846

Inventors:

Mark A. Peters - Arvada CO
Robert K. Johnson - Lakewood CO

Assignee:

Cyprus Metallurgical Processes Corporation - Los Angeles CA

International Classification:

C22B 1512
C22B 1104
C01G 500

US Classification:

75104

Abstract:

A process for recovering silver present in cuprous chloride solutions as a soluble silver chloride which comprises saturating the cuprous chloride solution with sodium chloride, subjecting the saturated solution to evaporation to co-crystallize the sodium chloride and silver chloride, separating the solid chlorides from the liquid, recovering silver from the sodium chloride-silver chloride crystals and reclaiming the sodium chloride, adding water to the liquid and cooling it to crystallize cuprous chloride. The procedure is adaptable to processes for recovering copper from its ores in which copper is reduced to cuprous chloride in a leach slurry followed by cooling the leach slurry to crystallize out the cuprous chloride from which copper is recovered by conventional techniques.

Appl. No.:

5/725929

Inventors:

Mark A. Peters - Arvada CO

Assignee:

Hazen Research, Inc. - Denver CO

International Classification:

C22B 1924

US Classification:

75103

Abstract:

A method for recovering a substantially impurity-free zinc oxide product from steel-making flue dust or a similar material which comprises leaching the flue dust with concentrated ammonia and carbon dioxide to dissolve zinc and unwanted impurities, cementing the leach filtrate with zinc to remove copper, cadmium, and lead impurities, conducting a steam distillation on the cementation filtrate to precipitate basic zinc carbonate, remove the ammonia and carbon dioxide, and iron impurities, and filtering to provide a residue of essentially basic zinc carbonate, sulfur, and chromium. This residue is then washed to remove soluble sulfates, dried, and calcined at high temperatures to break down the basic zinc carbonate into zinc oxide, water washed to remove chromium and the residue of the water wash dried to produce the desired impurity-free zinc oxide product. The two water washes may be combined into one step performed after the calcining step to remove both sulfur and chromium in one wash step.

Assignee:

Cyprus Metallurgical Processes Corporation - Los Angeles CA

International Classification:

C22B 1100

US Classification:

75118R

Abstract:

A process for recovering silver from chloride solutions comprising contacting the solution with amalgams of various metals from Groups 2b, 4a, 5a, or 8b of the periodic table or copper to replace the metal with silver and recovering silver from the formed silver amalgam. The process provides an improvement in the process for recovering copper from its ores in which the copper in the ore is solubilized as cuprous copper in a leach liquor and the copper recovered from the leach liquor as cuprous chloride by crystallization, the improvement being the removal of silver from the leach liquor prior to crystallization by use of the amalgam to produce substantially silver-free cuprous chloride crystals.
