Abstract
1. Способ переработки сульфидного медно-свинцово-цинкового концентрата, включающий загрузку в конвертер концентрата и окислительную плавку его с добавлением угля или углеродсодержащего материала, отличающийся тем, что первоначально в конвертер заливают штейн и продувают его углевоздушной смесью, затем на поверхность штейна загружают медно-свинцово-цинковый концентрат и штейн продувают кислородсодержащим дутьем до полного расплавления концентрата, после чего в конвертер загружают кварцевый и известковый флюсы и продолжают продувку до получения шлака и богатого штейна.2. Способ по п.1, отличающийся тем, что расход угля в углевоздушной смеси поддерживают 500 кг/т штейна при объемном отношении угля к воздуху в углевоздушной смеси 0,35 кг/м.3. Способ по п.1, отличающийся тем, что после получения шлака и богатого штейна их сливают на 70% и процесс переработки возобновляют с продувки расплава углевоздушной смесью.1. A method of processing a sulfide copper-lead-zinc concentrate, comprising loading the concentrate into the converter and oxidizing it with coal or carbon-containing material, characterized in that the matte is initially poured into the converter and the mixture is blown with an air-carbon mixture, then copper is loaded onto the matte lead-zinc concentrate and matte are purged with oxygen-containing blast until the concentrate is completely melted, after which quartz and lime fluxes are loaded into the converter and the purge continues of the slag and rich shteyna.2. The method according to claim 1, characterized in that the consumption of coal in the carbohydrate mixture is supported by 500 kg / t of matte with a volumetric ratio of coal to air in the carbohydrate mixture of 0.35 kg / m. The method according to claim 1, characterized in that after receiving the slag and the rich matte, they are drained by 70% and the processing process is resumed from the melt blowing with a carbohydrate mixture.
