| titleOfInvention | Recovered sulphur and lead, zinc, the technique of silver in a kind of oxygen-enriched direct leached mud from zinc concentrate or lead and zinc industry |
| abstract | The invention discloses one kind is from Recovered sulphur and lead in the oxygen-enriched direct leached mud of zinc concentrate or lead and zinc industry, zinc, the technique of silver, by undressed process or through drying, grinding, the zinc concentrate that pre-process of screening or the oxygen-enriched direct leached mud addition of lead and zinc industry are pre-loaded with the heater by the sulfur extraction agent and additive mixed liquor of the metering of liquid-solid ratio 8 15, after intensification heating response, filter while hot, filtrate obtains sulfur product after refiltering through cooling, filter residue after sulfur extraction agent and ethanol washing returns lead system and reclaims lead, silver, cleaning solution is returned after reclaiming through volatilization cooling and is used, sulfur extraction agent regenerates return extraction sulphur operation circulation after filtering and participates in reaction, zinc-containing solution returns direct leaching system after filtering.The technical process and equipment are simple, and sulfur recovery rate and product quality are high, environmentally safe, can realize efficiently, economically extracting sulphur in flotation sulphur slag, also can realize efficiently, being economically separately recovered zinc and lead, silver in flotation sulphur slag. |
