Process For Recovery Of Gold From Gold Ores Using A Complexing Pretreatment And Sulfurous Acid Leaching

View page
US Patent:
51476177, Sep 15, 1992
Filed:
May 21, 1991
Appl. No.:
7/703853
Inventors:
Freddie J. Touro - New Orleans LA
Tadeusz K. Wiewiorowski - New Orleans LA
Assignee:
Freeport-McMoRan Inc. - New Orleans LA
International Classification:
C01G 700
C22B 306
C22B 1106
US Classification:
423 27
Abstract:
A process for recovering gold from gold-bearing ores includes the steps of forming a slurry of ground ore and treating the ore with an oxidizing and complexing agent such as hydrogen sulfide or a sulfide salt. A chelating agent, SO. sub. 2, air, and an anion exchange resin are added to the slurry to subject the ore to a simultaneous sulfurous acid leaching and anion exchange resin adsorption step in the presence of dissolved oxygen. The gold transfers to the resin which is then removed from the slurry. The gold is then separted from the resin by chemical stripping. Alternately, the ground ore is blended with an oxidizing agent such as calcium hypochlorite and then with a gold-complexing agent. The ore blend is slurried in water, with the addition of a chelating agent, SO. sub. 2, air and an anion exchange resin to effect the leaching and adsorption of gold values.

Sulfide Treatment To Inhibit Mercury Adsorption Onto Activated Carbon In Carbon-In-Pulp Gold Recovery Circuits

View page
US Patent:
47342706, Mar 29, 1988
Filed:
Apr 11, 1986
Appl. No.:
6/850677
Inventors:
Freddie J. Touro - New Orleans LA
Delbert A. Lipps - Mandeville LA
International Classification:
C01G 700
US Classification:
423 29
Abstract:
In this invention sulfide compounds are added to mercury and precious metal-containing carbonaceous ore slurries prior to the slurry being processed by a carbon-in-pulp system. The sulfide compound inhibits the mercury from being adsorbed onto the activated carbon by reacting with the mercury to form mercuric sulfide and by inhibiting the dissolution of mercury from the ore. The mercuric sulfide precipitate displays no activity toward the activated carbon. The sulfiding procedure is performed with a sufficient amount of sulfide-providing compound to provide at least about 30 times the stoichiometric amount of sulfide ions required to react with the mercury in the ore slurry.

Sulfide As A Hypochlorite Kill Agent

View page
US Patent:
46055371, Aug 12, 1986
Filed:
Sep 17, 1984
Appl. No.:
6/651087
Inventors:
Freddie J. Touro - New Orleans LA
Assignee:
Freeport Minerals Company - New York NY
International Classification:
B01D 1100
US Classification:
423 29
Abstract:
Residual hypochlorite contained in chlorinated slurries of either carbonaceous gold-containing ores or mixtures of carbonaceous and oxide gold-containing ores are reduced by reaction with sulfide ion-providing chemical compounds preferably sodium hydrosulfide, sodium sulfide or hydrogen sulfide. The hypochlorite "kill" step enables subsequent cyanide leach operations to be conducted more efficiently.

Process For The Removal Of Mercury From Precious Metal-Cyanide Liquors

View page
US Patent:
47269391, Feb 23, 1988
Filed:
Dec 23, 1985
Appl. No.:
6/812919
Inventors:
Freddie J. Touro - New Orleans LA
International Classification:
C10G 1300
US Classification:
423101
Abstract:
This invention is a process for removing mercury from the desorption or cyanide liquor of a precious metal recovery, cyanide leach system. A sulfide ion-producing compound and a flocculating agent are added to the desorption liquor to form and flocculate mercuric sulfide. The desorption liquor typically has a cyanide concentration of between about 0. 5 percent and about 2. 0 percent by weight. The flocculated mercuric sulfide is separated from a substantially mercury-free precious metal-containing, cyanide solution.

Autoclave System For Leaching Sulfide Concentrates

View page
US Patent:
39619087, Jun 8, 1976
Filed:
Feb 27, 1974
Appl. No.:
5/446412
Inventors:
Freddie J. Touro - New Orleans LA
Assignee:
Freeport Minerals Company - New York NY
International Classification:
B01J 304
C01G 302
C22B 1500
US Classification:
23290
Abstract:
A method and apparatus for high temperature-high pressure acid leaching of sulfide ores is described. The apparatus includes an autoclave having a plurality of pressurized compartments and a water removing-heat removing condenser. Means are described for the introduction of a neutralizing agent directly into the autoclave in order to maintain the acidity of the slurry at a level where substantially all of the iron present in the slurry will form an insoluble iron oxide precipitate. Means are described for removing the gaseous products resulting from the introduction of the neutralizing agent while avoiding contamination thereby of a substantial portion of the oxygen.

Pressure Chlorination Of Refractory Gold Ores

View page
US Patent:
52366766, Aug 17, 1993
Filed:
Jun 11, 1992
Appl. No.:
7/897000
Inventors:
Freddie J. Touro - New Orleans LA
Roy A. Pickren - Baton Rouge LA
Assignee:
Freeport-McMoRan, Inc. - New Orleans LA
International Classification:
C22B 312
US Classification:
423 29
Abstract:
A method and apparatus are described for recovering gold from aqueous slurries of refractory gold ores containing sulfidic and/or carbonaceous matter. The method entails pretreating an ore slurry with chlorine in a multi-compartment autoclave operated at an elevated pressure. The chlorine used in this pressure chlorination pretreatment can be in either the gaseous or liquid state. Following the removal of residual chlorine from the pretreated ore slurry, said slurry is transferred to a conventional cyanide leach/carbon adsorption circuit to recover the gold values.

Oxidation-Leaching Of Chalcopyrite

View page
US Patent:
39624021, Jun 8, 1976
Filed:
Feb 27, 1974
Appl. No.:
5/446315
Inventors:
Freddie J. Touro - New Orleans LA
Assignee:
Freeport Minerals Company - New York NY
International Classification:
C01G 310
US Classification:
423 35
Abstract:
A method is described for the oxidation-leaching of chalcopyrite concentrates at high temperatures and pressures for the extraction of copper values as copper sulfate in which temperatures are maintained between about 425. degree. and 450. degree. F, oxygen partial pressures of between about 50 and 200 psi are provided, and levels of acidity are permitted to increase above about 50 grams of H. sub. 2 SO. sub. 4 per liter in order to obtain maximum rates of extraction of virtually all of the copper. Thereafter, while maintaining the temperature and pressure at elevated levels, the acidity of the slurry is reduced to between about 10 and 40 grams of H. sub. 2 SO. sub. 4 per liter in order to obtain reduction of dissolved iron to optimal levels. The resulting slurry is then cooled and further processed for the production of a very pure copper sulfate solution.

Process For Recovery Of Gold From Refractory Gold Ores Using Sulfurous Acid As The Leaching Agent

View page
US Patent:
51476185, Sep 15, 1992
Filed:
May 21, 1991
Appl. No.:
7/703843
Inventors:
Freddie J. Touro - New Orleans LA
Tadeusz K. Wiewiorowski - New Orleans LA
Assignee:
Freeport-McMoRan Inc. - New Orleans LA
International Classification:
C01G 700
C22B 306
C22B 1106
US Classification:
423 27
Abstract:
A process for recovering gold from refractory gold-bearing ores uses sulfurous acid as the leaching agent to form a gold-sulfite complex. The ore is ground, slurried blended with a chelating agent and then subjected to a simultaneous dissolved SO. sub. 2 leaching and anion exchange resin adsorption step in the presence of dissolved oxygen. The gold transfers to the resin which is later separated from the resin by chemical stripping.
