| titleOfInvention | METHOD FOR PROCESSING TIN CONTAINING SULFIDE TAILS AND FIRING APPARATUS FOR ITS IMPLEMENTATION |
| abstract | 1. A method of processing tin-containing sulfide tails, including firing them with the addition of a sulfidizing agent and a reducing agent at temperatures up to 650 ° C and with the removal of arsenic compounds, characterized in that the firing is carried out with the addition of 0.05-0.1% wood sawdust to the mixture to neutralize oxygen in the mixture at a temperature of up to 350 ° C, then up to 650 ° C, and the arsenic sulfide vapor formed is cooled in a condenser from 650 to 60 ° C. 2. A method for processing tin-containing sulfide tails according to claim 1, characterized in that the arsenic sulfide vapor is removed and cooled first to 300 ° C, and then to a temperature of up to 60 ° C. The roasting apparatus, comprising a heat-insulated heated furnace in the form of a pipe with an axial charge transfer screw, equipped with a loading hopper and an unloading shutter at the other end, characterized in that it is equipped with heaters of 3 heating sections: 20-350; 350-500 and 500-650 ° C, and the middle zone at the final section 3 / 4-5 / 6 of the length of the furnace pipe is equipped with a vapor removal window and connected to the condenser in the form of a pipe with a screw equipped with an arsenic sulfide discharge gate in the lower part and exhaust gas and equipped with 2 sections of cooling jackets to temperatures of 650-300 and 300-60 ° C. |
