Description
Известен способ переработки медистых шликеров плавкой их при 1100-1200°С совместно с сульфатом натри и углеродистым восстановителем .There is a method of processing cuprous slips by melting them at 1100-1200 ° C together with sodium sulfate and carbonaceous reducing agent.
Особенность предложенного способа заключаетс в том, что плавку ведут при 2150- 240П°С совместно с железной рудой и алюминиевой крупкой. Способ обеспечивает извлечение цветных металлов из шликеров, полученных при переработке пылей ферровольфрамового и ферромолибденового производств.The peculiarity of the proposed method is that smelting is carried out at 2150-240 ° C together with iron ore and aluminum grit. The method provides for the extraction of non-ferrous metals from slips obtained during the processing of ferrous-tungsten and ferromolybdenum dusts.
Сущность способа заключаетс в следующем .The essence of the method is as follows.
Шихта металлотермической плавки составл етс из железной руды, алюминиевой крупки и шликеров. Возможно применение в качестве восстановител ферросилици .The mixture of metallothermic smelting is composed of iron ore, aluminum grains and slips. It is possible to use ferrosilicon as a reducing agent.
Шликеры в состав шихты ввод тс измельченными с таким расчетом, чтобы тер.мичность шихты находилась в пределах 750- 900 ккал/кг. Плавка проводитс при 2150- 2400°С.Slickers are mixed in the mixture in such a way that the termination of the mixture is in the range of 750-900 kcal / kg. Melting is carried out at 2150-2400 ° C.
В процессе плавки образуетс железный сплав, в котором раствор етс медь. Свипец, висмут и олово испар ютс , и их возгоны улавливаютс в электрофильтрах. Испарению способствует практически полна нерастворимость свинца и висмута в железе. Возгоны перерабатываютс известными способами, например восстановительной электроплавкой.In the smelting process, an iron alloy is formed in which copper is dissolved. Svipets, bismuth and tin evaporate and their sublimates are captured in electrostatic precipitators. The evaporation is facilitated by the almost complete insolubility of lead and bismuth in iron. Sublimates are processed by known methods, for example, reduction electrofusion.
Железный сплав, содержащий 5-30% меди, перерабатываетс на заводах цветной металлургии .Iron alloy containing 5-30% copper is processed at non-ferrous metallurgy plants.
Пример. Шликеры, полученные при переработке пылей ферровольфрамового и ферромолибденового производств восстановительной плавкой, содержащие 17,2% висмута, 18,63% свинца, 45.75% меди, подвергают металлотермической плавке.Example. Schlickers, obtained by processing dusts of ferro-tungsten and ferromolybdenum production by reducing smelting, containing 17.2% bismuth, 18.63% lead, 45.75% copper, are subjected to metallothermic melting.
Состав шихты в кг: железна руда 1000, алюминиева круика 350, шликеры 350.The composition of the mixture in kg: iron ore 1000, aluminum cruise 350, slip 350.
Шликеры ввод т в количестве до 20% от веса шихты; при больших количествах снижаетс температура расплава и увеличиваетс содержание свинца и висмута в железном сплаве.Schlickers are introduced in an amount up to 20% by weight of the charge; with large quantities, the temperature of the melt decreases and the lead and bismuth content in the iron alloy increases.
В процессе плавки ири темиературе получают железный сплав, с содержанием жемеди 27,9% и возгоны, с содержа/о . )),, висмута. 30% свинца.In the process of melting iron and steel, an iron alloy is obtained, with a gold content of 27.9% and sublimates, with containing / o. )) ,, bismuth. 30% lead.
нием около 60 0,5% меди.about 60% to 0.5% copper.
Возгоны перерабатывают в электропечи восстановительной плавкой с получением свиниововисмутистого сплава, извлечение висмута в сплав составл ет 95-98%.Sublimates are processed in electric furnaces by smelting reduction with the production of pork-bentuminous alloy, the extraction of bismuth into the alloy is 95-98%.
Предмет изобретенп 34The subject of the invention 34
что, с целью извлечени цветных металлов из производств, плавку ведут при температуре шликеров, полученных нри переработке пылей 2150-2400°С совместно с железной рудой и ферровольфрамового и ферромолибденового алюминиевой крупкой.that, in order to extract non-ferrous metals from production, smelting is carried out at the temperature of slips obtained by processing dusts 2150-2400 ° C together with iron ore and ferro-tungsten and ferromolybdenum aluminum grit.
