Изобретение относитс к цветной металлургии и, в частности к способам переработки шлаков цветной металлургии с извлечением цветных металлов.The invention relates to non-ferrous metallurgy and, in particular, to methods for processing slags from non-ferrous metallurgy with extraction of non-ferrous metals.
Известен способ хлоридной плавки шихты, состо щей из металлсодержаш,его сырь , хлорируюш .их агентов, флюса и кокса. По этому способу возгоны могут получатьс в оксихлоридной форме.The known method of chloride smelting of the charge consisting of metal-containing, its raw materials, chlorinated agents, flux and coke. By this method, sublimates can be obtained in oxychloride form.
Цель изобретени - обеспечение непрерывности процесса и получение возгонов в хлоридной форме.The purpose of the invention is to ensure the continuity of the process and obtain sublimates in chloride form.
Предлагаемый способ отличаетс тем, что, плавку ведут электротермическим методом в нейтрально-восстановительной атмосфере, не содержащей свободного кислорода, при избыточном давлении до 50 мм вод. ст.The proposed method is characterized in that the melting is carried out by an electrothermal method in a neutral reducing atmosphere that does not contain free oxygen, with an overpressure of up to 50 mm of water. Art.
Шихта, состо ща из отвальных шлаков свинцового производства, хлорагентов CaCl2 и NaC в смеси с кварцевым флюсом и коксом , непрерывно поступает в герметизированную печь, а возгоны цветных металлов через короткий газоход непрерывно поступают в полый теплоизолированный конденсатор и конденсируютс там в жидком состо нии. Образующа с в печи расплавленна масса (стеклошлак и чугун), по мере накоплени выпускаютс . Плавка ведетс при давлении 0-ь -f-50 мм вод. ст. с подачей в печь технического азота.The mixture consisting of waste slag from lead production, chlorine agents CaCl2 and NaC mixed with quartz flux and coke, continuously enters a sealed furnace, and non-ferrous metals sublimates through a short duct continuously enter a hollow heat-insulated condenser and condense there in a liquid state. The molten mass produced in the furnace (glass slag and cast iron) is released as it accumulates. Melting is carried out at a pressure of 0 -f-50 mm water. Art. with the supply of technical nitrogen into the furnace.
Возгоны по своим физико-химическим свойствам представл ют смеоь хлоридов и содержат ZnCl2 60,0%-70,0%; РвСЬ-8,0- 12,0%, 8,0-12,0%, CuCl 0,6-1,80/о, сумма NaCl+CaCl2 6,0-14,0%, сумма других хлоридов металлов 1,0-8,0%.By their physicochemical properties, sublimates are mixtures of chlorides and contain ZnCl2 60.0% -70.0%; RVS-8.0- 12.0%, 8.0-12.0%, CuCl 0.6-1.80 / o, the amount of NaCl + CaCl2 6.0-14.0%, the sum of other metal chlorides 1, 0-8.0%.
Предмет изобретени Subject invention
Способ хлоридной плавки шихты, состо щей из металлсодержащего сырь , хлоридов щелочных и щелочноземельных металлов с добавкой кварцсодержащих материалов и кокса , отличающийс тем, что, с целью обеспечени непрерывности процесса и получени возгонов в хлоридной форме, плавку ведут электротермическим методом в нейтральновосстановительной атмосфере, не содержащей свободного кислорода, при избыточном давлеНИИ до 50 мм вод. ст.The method of chloride smelting of the charge consisting of metal-containing raw materials, alkali and alkaline earth metal chlorides with the addition of quartz-containing materials and coke, characterized in that, in order to ensure the continuity of the process and obtain sublimates in the chloride form, the smelting is carried out by an electrothermal method in a neutral reducing atmosphere not containing free oxygen, with an overpressure of up to 50 mm of water. Art.
