Abstract: Processes for and compositions utilized in the recovery of noble metals from noble metal containing substances by subjecting such substances- preferably in comminuted form- to the action of a solvent preferably comprising diacetone alcohol as a major component, water, minor amounts of glacial acetic acid potassium iodide and elemental iodine. Solvation of the noble metal occurs during agitation and heating of the slurry. The noble metal contents are removed from the noble metal pregnant solution by displacement onto a non-noble metal surface. The solid noble metal containing residue is treated with sufficient aqueous hydroxide solution to convert excess non-noble metal into its water-soluble salt. The remaining insoluble material containing the noble metal recovered is rinsed to remove any remaining unreacted alkali and the soluble salts and is then digested with concentrated sulfuric acid to dissolve any remaining acid soluble impurities, the remaining acid insoluble residue is rinsed, dried and comprises substantially pure noble metal.

Abstract: WASTE STACK GASES OR OTHER GASES CONTAINING SULFUR DIOXIDE GAS ARE PASSED INTO A SYSTEM INITIALLY CONTAINING 90 TO 95% OF FINELY DIVIDED METALLIC OXIDES AND METALLIC SILICATES, INTIMATELY ADMIXED WITH AN ADDITIVE COMPRISING NOT LESS THAN 3% OR MORE THAN 5% WATER, NOT LESS THAN 2% OR MORE THAN 5% DISSOLVED ALKALI HYDROXIDE SUCH AS SODIUM HYDROXIDE OR SODIUM METASILICATE AND BETWEEN 01% TO 0.1% STANNUOUS CHLORIDE OR STANNOUS HYDRIDE ALL OF THE ABOVE NOTED PERCENTAGES BEING BASED ON PARTS BY WEIGHT OF EACH NOTED INGREDIENT PRESENT IN EVERY 100 PARTS BY WEIGHT OF THE SLAG CONTAINING SYSTEM. THE SYSTEM IS STRONGLY AGITATED DURING THE TIME THE WASTE STACK GAS IS BEING PASSED THERETHROUGH. THE SULFUR DIOXIDE CONSTITUENT OF THE STACK GAS IS ENTRAPPED IN THE SLAG SYSTEM AND CAN BE LIBERATED THEREFROM IN ESSENTIALLY PURE FORM BY SUBSEQUENT HEAT TREATMENT OF THE ENTRAPMENT SYSTEM. THE SYSTEM CAN THEREUPON BE RESUED REPEATEDLY FOR ENTRAPMENT OF FURTHER SO2 GAS BECAUSE IT IS ESSENTIALLY REGERATABLE DUE TO THE ADDITION OF THE ADDITIVES NOTED ABOVE WHICH PREVENT UNDUE OXIDATION OF THE COMPONENTS OF THE SYSTEM.

Abstract: PROCESSES FOR AND COMPOSITIONS UTILIZED IN THE RECOVERY OF NOBLE METALS FROM NOBLE METAL CONTAINING SUBSTANCES BY SUBJECTING SUCH SUBSTANCES-PREFERABLY IN COMMINUTED FORM-TO THE ACTION OF A SOLVENT PREFERABLY COMPRISING DIACETONE ALCOHOL AS A MAJOR COMPONENT, WATER, MINOR AMOUNTS OF GLACIAL ACETIC ACID, POTASSIUM IODIDE AND ELEMETAL IODINE. SOLVATION OF THE NOBLE METAL OCCURS DURING AGITATION AND HEATING OF THE SLURRY. THE NOBLE METAL CONTANTS ARE REMOVED FROM THE NOBLE METAL PREGNANT SOLUTION BY DISPLACEMENT ONTO A NON-NOBLE METAL SURFACE. THE SOLID NOBLE METAL CONTAINING RESIDUE IS TREATED WITH SUFFICIENT AQUEOUS HYDROXIDE SOLUTION TO CONVERT EXCESS NON-NOBLE METAL INTO ITS WATER-SOLUBLE SALT. THE REMAINING INSOLUBLE MATERIAL CONTAINING THE NOBLE METAL RECOVERED IS RINSED TO REMOVE ANY REMAINING UNREACTED ALKALI AND THE SOLUBLE SALTS AND IS THEN DIGESTED WITH CONCENTRATED SULFURIC ACID TO DISSOLVE ANY REMAINING ACID SOLUBLE IMPURITIES, THE REMAINING ACID INSOLUBLE RESIDUE IS RINSED, DRIED AND COMPRISES SUBSTANTIALLY PURE NOBLE METAL.

Abstract: Processes for and compositions utilized in the recovery of the gold content of gold containing substances by subjecting such substances -preferably in comminuted form- to the action of one of the following solvent system families: A. Aqueous gold solvation systems comprising primary or secondary mono-hydroxy alcohols, saccharides and/or carboxylic acids and iodine or bromine. B. Aqueous iodine-containing gold solvation systems comprising primary or secondary monohydroxy alcohols and ditri- and polyhydric alcohols in the place of or in addition to saccharides and carboxylic acids. C. Essentially non-aqueous gold solvating systems comprising secondary alcohols and iodine. Solvation of the gold occurs during agitation and heating of the slurry. The gold contents are removed from the gold pregnant solution by displacement onto a non-noble metal surface. The solid gold containing residue is treated with sufficient aqueous hydroxide solution to convert excess non-noble metal into its water-soluble salt. The remaining insoluble material containing the gold metal recovered is rinsed to remove any remaining unreacted alkali and the soluble salts and is then digested with concentrated sulfuric acid to dissolve any remaining acid soluble impurities, the remaining acid insoluble residue is rinsed, dried and comprises substantially pure gold metal.

Abstract: A PROCESS FOR BENEFICATION OF WASTE COPPER SLAG TO BE USED FOR THE ENTRAPMENT OF SULFUR DIOXIDE FROM WASTE GASES BY CONTACTING THE WASTE SLAG WITH AN AQUEOUS SOLUTION OF AMMONIA GAS TO REMOVE THE REACTIVE COPPER CONTENT, AND ZINC CONTENT, IF ANY PRESENT IN THE WASTE SLAG. THE REMOVAL OF THE COPPER BY THE AQUEOUS AMMONIA SOLUTION IS ACCOMPLISHED WITHOUT THE PRESENCE OF ANY DISSOLVED AMMONIUM SALTS OR THE ADDITION OF AIR OR OTHER OXIDIZING AGENT TO THE REACTION. AFTER DISSOLVING THE COPPER VALUES AND ZINC VALUES, IF DESIRED, THEY MAY BE RECOVERED FROM THE AMMONIA GAS SOLUTION BY DISPLACEMENT.

Abstract: A PROCESS IS DISCLOSED WHEREIN SULFUR DIOXIDE GAS OR SULFUR DIOXIDE CONTAINING WASTE STACK GASES, ARE PASSED INTO A BED OF MIXED METALLIC OXIDES AND SILICATES WHICH CONTAINS NOT LESS THAN ABOUT 1% OR MORE THAN ABOUT 10% OF ITS WEIGHT IN ADDED WATER TO PRODUCE A DRY, PARTICULATE PRODUCT COMPRISING METALLIC SULFITE SALTS, META-SILICIC ACID, ADSORBED SULFUR DIOXIDE, AND UNREACTED OXIDIC AND SILICEOUS MATERIAL OF A KIND AND AMOUNT DEPENDENT UPON THE CHEMICAL NATURE AND REACTABILITY WITH SULFUR DIOXIDE GAS OF THE METALLIC OXIDE SILICATE MATERIAL PROCESSED. THE PRODUCT WHEN SUBSEQUENTLY MODERATELY HEATED RELEASES SUBSTANTIALLY EQUIMOLAR AMOUNTS OF SULFUR DIOXIDE IN CONJUNCTION WITH THE RELEASE OF ONLY MINOR AMOUNTS OF WATER.
