Недостатком известной шихты вл етс невозможность комплексного извлечени цветных и редких металло Наиболее близкой по технической сущности и достигаемому результату к предлагаемой вл етс шихта дл элeктpoтepм iчecкoй плавки, включающа металлсодержащее сырье, хлорид кальци , хлорид натри , кокс и флюс л . В качестве металлсодержащего сырь известна шихта содержит шлак а в качестве флюса - кварцит. Недостатком известной шихты вл етс невозможность получени черново свинца и низкое извлечение редк1тх и цветных металлов. Целью изобретени вл етс получение чернового свинца и обеспечение комплексности извлечени редких и цветных металлов. С этой целью шихта дл электротермической плавки, включающа мета лсодержащее сьфье, хлорид кальци , хлорид натри , кокс и флюс содержит в качестве металлсодержащего сырь свинецсодержащий материал, а качестве флюса - сульфат натри приAbout the invention The invention relates to non-ferrous metallurgy and can be used in the processing of lead-containing materials, ferrous lead plants and tar lead concentrates. The known charge ij, used in the processing of lead production dust, contains,%: sodium sulfate 20-25, sulphide concentrate 5-10, carbon-containing reducing agent 4-5, lead dust production the rest. A disadvantage of the known charge is the impossibility of complex extraction of non-ferrous and rare metals. The closest to the technical essence and the achieved result to the proposed is the charge for electric melting, including metal-containing raw materials, calcium chloride, sodium chloride, coke and flux. As a metal-containing raw material, the known charge contains slag and quartzite as the flux. A disadvantage of the known charge is the impossibility of obtaining crude lead and the low recovery of rare and non-ferrous metals. The aim of the invention is to obtain rough lead and to ensure the complex extraction of rare and non-ferrous metals. To this end, the mixture for electrothermal smelting, including methanol-containing sulfur, calcium chloride, sodium chloride, coke, and flux, contains lead-containing material as the metal-containing raw material, and sodium sulfate as the flux

Продуктами электроплавки вл ютс черновой свинец, коллектирую1чий медь и благородные металлы, штейно-шлаковый расплав, в который на 80% переходит цинк; возгоны, состо щие из хлоридов свинца, цинка, кадми , инди , селена, теллура, сурьмы и других редких металлов. Хлоридные возгоны перерабатывают известным гидрометаллургическим способом. Примеры осуществлени плавки описанной шихты приведены в табл. 1. В качестве свинецсодержащего материала использовали аглопыли следующего состава, вес. %: авинец 51,8; цинк 2; медь 1,72, кадмий 1,3; селен 0,65; теллур 0,95, индий 0,03; сурьма О,11 или свинцовый концентрат следующего состава, вес. %: свинец 53,2, медь 3,7,- цинк 6,38; кадмий 0,081;- селен 0,067; теллур 0,0097; индий 0,0014. В табл. 2 приведены результаты плавки известной шихты. Как следует из приведенных данных, описываема шихта позвол ет получить в результате плавки черновой свинец и повысить извлечение цветных и редких металлов по сравнению с переработкой шихты известного состава. Таблица 1An example of the following ratio of composites, yas. %: Sodium sulfate. 20-25 Sodium chloride 2-4 Calcium chloride 4-8 Cox3-6 Lead-containing material Remaining The starting mixture is directed to electrothermal chloride smelting, which is carried out at 1100-1250 ° C. Products of electric smelting are rough lead, collecting copper and precious metals, matte-slag melt, into which zinc passes by 80%; sublimates consisting of chlorides of lead, zinc, cadmium, indium, selenium, tellurium, antimony, and other rare metals. Chloride sublimates are processed by a known hydrometallurgical method. Examples of the implementation of the melting of the described mixture are given in table. 1. As a lead-containing material used agloply following composition, weight. %: Avinets 51.8; zinc 2; copper 1.72, cadmium 1.3; selenium 0.65; tellurium 0.95, indium 0.03; antimony O, 11 or lead concentrate of the following composition, weight. %: lead 53.2, copper 3.7, - zinc 6.38; cadmium 0.081; - selenium 0.067; tellurium 0.0097; indium 0.0014. In tab. 2 shows the results of melting known charge. As follows from the above data, the described charge makes it possible to obtain crude lead as a result of smelting and to increase the extraction of non-ferrous and rare metals in comparison with the processing of a charge of known composition.
