Recovery Of Metal Values From Cermet
US Patent:
7048774, May 23, 2006
Filed:
Feb 27, 2004
Appl. No.:
10/787085
Inventors:
Peter T. Halpin - Great Falls VA, US
Ulrich R. Schlegel - Warrenton VA, US
Kenneth E. Riegel - Orwigsburg PA, US
Ulrich R. Schlegel - Warrenton VA, US
Kenneth E. Riegel - Orwigsburg PA, US
Assignee:
World Resources Company - McLean VA
International Classification:
C22B 1/248
US Classification:
75300, 75414
Abstract:
Cermet material obtained from unused inert anodes, used inert anodes and cermet used in the production of inert anodes is beneficiated into a nonferrous metal concentrate composition from which metal values contained in the composition may be readily recovered by using a conventional smelting process. The invention also relates to the use of the composition in a smelting process for the recovery of metal values from the cermet composition of the invention.
Process For Recovering Metals And Metal Compounds From Mined Ore And Other Metal-Bearing Raw Source Materials
US Patent:
8177882, May 15, 2012
Filed:
Apr 29, 2010
Appl. No.:
12/770134
Inventors:
Peter T. Halpin - Great Falls VA, US
Ulrich R. Schlegel - Washington DC, US
Dale L. Schneck - Pottsville PA, US

Assignee:
World Resources Company - McLean VA
International Classification:
C22B 3/12
US Classification:
75739, 423 55
Abstract:
A method for selectively recovering a metal from mined ore and other metal-bearing raw source materials is disclosed. The method involves mixing with an aqueous medium a metal-bearing ore and/or other raw source material containing a first metal in an insoluble form, insoluble and/or soluble Cr in a Cr bearing material as a second metal, and organic and inorganic compounds to obtain a slurry containing the first metal in an insoluble form, insoluble and/or soluble Cr compound(s), and the organic and inorganic compounds; adjusting the pH of the slurry to an optimal range for Cr oxidation to convert Cr to an insoluble form; optionally adding a first oxidizer to the slurry to oxidize organic and inorganic compounds; selectively leaching the Cr by adding a leaching agent in an amount sufficient to obtain Cr in a soluble form while the first metal remains in the slurry in an insoluble form; filtering the slurry to obtain a filter cake containing the first metal in an insoluble form and a filtrate containing Cr in a soluble form; and recovering the filter cake containing the first metal in an insoluble form and/or filtrate containing Cr in a soluble form.
Recovery Of Metal Values From Cermet
US Patent:
2004017, Sep 16, 2004

Process For Recovering Metals And Metal Compounds From Mined Ore And Other Metal-Bearing Raw Source Materials
US Patent:
2012024, Oct 4, 2012
Filed:
Apr 24, 2012
Appl. No.:
13/454226
Inventors:
Peter T. HALPIN - Great Falls VA, US
Ulrich R. SCHLEGEL - Washington DC, US
Dale L. SCHNECK - Pottsville PA, US
Ulrich R. SCHLEGEL - Washington DC, US

International Classification:
C22B 3/12
C22C 27/06
C22B 34/32
C22C 27/06
C22B 34/32
US Classification:
75300, 75739, 420428
Abstract:
A filter cake, including a first metal in an insoluble form and/or filtrate comprising Cr in a soluble form, obtained by a method involving filtering an aqueous slurry of a metal-bearing raw source material comprising the first metal in an insoluble form, soluble and/or insoluble Cr in a Cr bearing material as a second metal, and organic and inorganic compounds, after adjusting the pH of the slurry to an alkaline pH sufficient to convert soluble Cr present to an insoluble form and selectively leaching the Cr by adding a leaching agent in an amount sufficient to convert Cr to a soluble form while the first metal remains in the slurry in an insoluble form.
Method Of Reducing Carbon Emissions And Improving The Environmental Performance Of Concentrate Producers And Smelters
US Patent:
2023005, Feb 23, 2023
Filed:
Oct 28, 2022
Appl. No.:
17/975764
Inventors:
- Jackson WY, US
Dale Schneck - Pottsville PA, US
Ulrich R. Schlegel - Washington DC, US
Dale Schneck - Pottsville PA, US
Ulrich R. Schlegel - Washington DC, US
Assignee:
WORLD RESOURCES COMPANY - Jackson WY
International Classification:
C22B 1/244
C22B 15/00
C22B 15/00
Abstract:
A process which improves the environmental performance of primary non-ferrous metal smelters by reducing carbon emissions, providing enhanced energy utilization, improving consumption efficiencies, and improving worker safety. The smelters include those that smelt nickel, copper and zinc. The process includes a step of drying feedstock prior to the addition of a product conditioning solution that includes saccharides as a primary ingredient. Sucrose and fructose are preferred saccharides. A base saccharide solution may be prepared by either diluting a concentrated saccharide syrup (75 to 85 brix), or by dissolving a dried powdered saccharide in water to a concentration that yeilds a syrup of between 20 and 30 Brix, more preferentially 25 Brix. The Brix may be measured with any commercially available refractometer capable of measuring the Brix of sugar solutions.
