Description
Изобретение относитс к цветной металлургии, в частности к переработке вторичного свинецсодержащего сырь .The invention relates to non-ferrous metallurgy, in particular to the processing of secondary lead-containing raw materials.
Цель изобретени - повышение степени извлечени свинца и сокращение трудозатрат.The purpose of the invention is to increase the degree of extraction of lead and reduce labor costs.
На фиг. 1 изображена зависимость извлечени свинца от концентрации сол ной кислоты ( соом (дл кривой 1) и 20% (дл кривой 2), на фиг. 2 - зависимость извлечени свинца от соотношени концентрации кислот (Ср(., 20Z).FIG. Figure 1 shows the dependence of the extraction of lead on the concentration of hydrochloric acid (soy (for curve 1) and 20% (for curve 2), Fig. 2 shows the dependence of the extraction of lead on the ratio of the concentration of acids (Cf (., 20Z).
Дл переработки берут пыли, содержащие , мас.%: свинец 53,0, цинк 1,7; олово 0,9, сурьма 0,5; кадмий 0,04; медь 0,12; таллий 0,12; индий 0,009.For processing take dust containing, wt.%: Lead 53.0, zinc 1.7; tin 0.9, antimony 0.5; cadmium 0.04; copper 0.12; thallium 0.12; indium 0.009.
Во всех опытах дл переработки берут по 100 г пыли.In all experiments for processing take 100 g of dust.
Пыль обрабатывали в течение 30 мин со смесью сол ной и уксусной кислот в указанных соотнощени х.После отстаивани гор чий раствор сливают (декантируют) в охлажденный стакан. При охлаждении до 10-20 С из него выпадает осадок хлорида свица . Раствор фильтрованием отдел ют от хлорида свинца и используют дл повторной обработки пыли. Соотношени кислот после первичной обработки пратически не измен етс . Во всех случа х при соотношени х массы пыли к объему раствора 1:(15-20) за две - одну операцию практически полностью извлекают свинец .из пылей. ПоказатеThe dust was treated for 30 minutes with a mixture of hydrochloric and acetic acids in the indicated ratios. After settling, the hot solution was drained (decanted) into a cooled glass. When cooled to 10-20 ° C, precipitated chloride precipitates out of it. The solution is separated from the lead chloride by filtration and is used to recycle the dust. The ratio of the acids after the initial treatment does not change the practical effect. In all cases, when the ratio of the mass of dust to the volume of the solution is 1: (15-20) in two - one operation, lead is almost completely removed from the dust. Show

ли процесса извлечени свинца из свин- цово-хлоридньгх пьи1ей приведены в таблице . Из приведенных в таблице и на фиг. 1 и 2 данньпх следует, что наиболее полное (94-98,6%) извлечение свинца и цинка (95-96%) достигаетс при соотношении концентраций сол ной и уксусной кислот 1:(0,5-2), содержании сол ной кислоты в растворе 15-25%, температуре обработки 90 - 100°С, температуре выкристаллизации хлорида свинца 10-20°С и соотношении массы пыли к объему раствора 1:(15- 20) .Whether the process of extracting lead from lead chloride is given in the table. From the table and FIG. 1 and 2 data it follows that the most complete (94-98.6%) extraction of lead and zinc (95-96%) is achieved when the ratio of hydrochloric and acetic acids 1: (0.5-2), hydrochloric acid content in a solution of 15–25%, a treatment temperature of 90–100 ° C, a temperature for the crystallization of lead chloride 10–20 ° C, and a ratio of dust mass to solution volume 1: (15-20).
Полученньш хлорид свинца содержит, мас.%: свинец 7А,49| цинк 210 , кадмий 2-10 , медь 1-10 , олово, сурьма , индий, таллий не обнаружены.The resulting lead chloride contains, wt%: lead 7A, 49 | zinc 210, cadmium 2-10, copper 1-10, tin, antimony, indium, thallium were not found.
Технико-экономическа эффективность предлагаемого способа по сравнению с известным состоит в следующем: на 4-5% увеличиваетс извлечение свинца и на 1-2% - цинка в раствор, что при стоимости хлорида свинца 2,4 руб, за 1 кг позволит сэкономить 100-120 р уб. с каждой тонны готовой продукгии на 1-2 пор дка повышаетс чистота получаемого хлорида свинца за счет перекристаллизации в процессе получени из сол но-уксусно-кислого раствора; упрощаетс процесс переработки пылей за счет исключени многостадийного разделени твердых и жидких фаз с использованием сложных технологических устройств (гидроциклотронов), что обеспечивает снижение трудовых затрат на проведение процесса.The technical and economic efficiency of the proposed method as compared to the known one is as follows: lead extraction increases by 4-5% and zinc per solution by 1-2%, which, at a lead chloride cost of 2.4 rubles, will save 100- kg per 1 kg. 120 p ub. the purity of the resulting lead chloride is increased by 1–2 times from each ton of finished products due to recrystallization in the process of obtaining from a hydrochloric acid solution; Dust processing is simplified by eliminating the multistage separation of solid and liquid phases using complex technological devices (hydrocyclotrons), which reduces the labor costs of the process.
