| titleOfInvention | Process for low temperature chlorination of roasted products from an iron sulphide roasting process prior to leaching out the nonferrous metal present therein |
| abstract | A PROCESS FOR ROASTING SULPHIDIC IRON MATERIAL OR MIXTURES OF SULPHIDIC AND OXIDIC IRON MATERIAL AND CHLORINATING NONFERROUS METALS PRESENT IN SAID MATERIALS AT LOW TEMPERATURES, WHEREAFTER THE CHLORINATED NONFERROUS METALS ARE LEACHED OUT AND RECOVERED, IN WHICH THE MATERIAL IS FIRST ROASTED IN A FLUIDIZED BED REACTOR AT A TEMPERATURE BETWEEN 700 TO 1100*C., WHILE INTRODUCING OXYGEN OR A GAS CONTAINING FREE OXYGEN IN A LIMITED AMOUNT, WHEREAFTER THE MATERIAL, SUBSEQUENT TO DESULPHURIZING AND COOLING IS TREATED WITH CHLORINE, HYDROGEN CHLORIDE OR IRON CHLORIDE OR A GAS CONTAINING CHLORINE OR HYDROGEN CHLORIDE, IN A FLUIDIZED BED REACTOR AT A TEMPERATURE AT 300-600*C., WHILE MAINTAINING FLUIDIZATION BY INTRODUCING A GAS FROM BENEATH THE REACTOR, SAID GAS BEING OPTIONALLY MIXED WITH THE CHLORINATING SUBSTANCE. |
