| titleOfInvention | Processing method of sulphide pyrrhotine-pentlandite concentrates containing precious metals |
| abstract | FIELD: metallurgy. n SUBSTANCE: for carrying out the leaching process of pentlandite-pyrrhotite concentrate at a temperature of 90-105°C with the feeding of sulfuric acid and sodium sulfate into the autoclave, the oxygen partial pressure is increased from more than 0.5 to 1.5 MPa. The oxidated pulp is delivered for separation to solid and liquid phases. The metal containing solution is sent for processing, and solid phase - for floatation, during it sulfur sulphide concentrate and tails of dump quality are produced, to them maximum 5% of non-ferrous and maximum 5-15% of precious metal are transferred. The method is applicable for the leaching of pyrrhotite-pentlandite concentrates at any nickel content in the range of 0.5-20%. n EFFECT: intensification of the leaching process. n 2 cl, 3 tbl, 3 ex |
