Description
Изобретение относитс к цветной металлургии, в частности к технологии конвертировани медно-свинцовых штейнов.This invention relates to non-ferrous metallurgy, in particular, to the technology for converting copper-lead mattes.
Наиболее близким по технической сути и достигаемому эффекту к предлагаемому вл етс способ конвертировани свинецсодержащих медных штейнов , включающий продувку их в первом и втором периодах конвертировани окислительным газом, подачу кварцевой руды, известн ка и оборотных шлаков 11.The closest to the technical essence and the achieved effect to the proposed is a method of converting lead-containing copper mattes, including purging them in the first and second converting periods with oxidizing gas, feeding quartz ore, limestone and circulating slags 11.
Однако известный способ не позвол ет достаточно полно перевести свинец в возгоны при переработке медных штейнов с повышенным содержанием свинца (6-10%), а кроме того, не повышаетс извлечение меди в черновой металл и качество черновой меди .However, the known method does not allow lead to be sufficiently fully converted into sublimates during the processing of copper mattes with an elevated lead content (6-10%), and, moreover, the recovery of copper into the rough metal and the quality of blister copper do not improve.
Цель изобретени - псвышение степени возгонки свинца, сурьмы и мышь ка из конверторной массы, повышение извлечени меди и улучшение качества черновой меди.The purpose of the invention is to increase the degree of sublimation of lead, antimony and mouse from the converter mass, increase copper recovery and improve the quality of blister copper.
Постав.ленна цель достигаетс тем, что в известном способе конвертировани штейнов, включающем продувкуThe aim of the goal is achieved by the fact that in the known method of converting mattes, including blowing
их окислительным газом в первом и втором периодах конвертировани , подачу кварцевой руды, известн ка и оборотных шлаков, в первом периоде на каждую порцию штейна после подачи смеси кварцевой руды и известн ка в расплав подают высокосернистый пиритный концентрат в количестве 50-80 кг на 1 т штейна со скоростью 900-1200 кг/мин.their oxidizing gas in the first and second conversion periods, the supply of quartz ore, limestone and circulating slag, in the first period for each batch of matte after feeding the mixture of quartz ore and limestone in the melt serves sour pyrite concentrate in the amount of 50-80 kg per 1 ton matte with a speed of 900-1200 kg / min.
При образовании во втором периоде конвертировани шлака на него подают пиритный концентрат в количестве 80-120 кг на 1 т шлака.When it forms in the second period of slag conversion, it is supplied with pyrite concentrate in the amount of 80-120 kg per 1 ton of slag.
Способ осуществл етс следующим образом.The method is carried out as follows.
