| titleOfInvention | Method for precious metals concentrate production from copper-nickel converter matte |
| abstract | FIELD: chemistry. n SUBSTANCE: method comprises oxidative hydrochloride leaching by gradual supply of metallized fraction to a chloride solution at ORP of 400-450 mV with transfer of the main part of non-ferrous metals to the solution, and precious metals and sulfur concentrating in the residue. The sulfur is leached from the residue with a solution of sodium sulfite or sulfide with a concentration of 150-250 g/l and 100-150 g/l, respectively, with S:L = 1:5-10 to obtain a precious metal concentrate and a sulfur-containing solution, which is delivered to converter matte reprocessing. The precious metal concentrate is subjected to liquid-phase sulphatization at a temperature of 180-210°C to obtain enriched concentrate. Additional sulphatization of the precious metal concentrate at a temperature of 280-300°C to obtain a palladium-platinum concentrate and platinum satellite metal concentrate is possible. The total content of platinum and palladium in the concentrate increases 1.6-11 times. n EFFECT: reduced losses of precious metal and increased content thereof in the concentrate. n 4 cl, 7 ex |
