Abstract
Description
Изобретение относится к цветной металлургии и может быть использовано в технологии синтеза свинцовых солей. The invention relates to ferrous metallurgy and can be used in the technology of the synthesis of lead salts.
Известен способ получения раствора свинцовой соли для производства свинцовых крон и других химических соединений (Карякин Ю.В., Ангелов И.И. Чистые химические вещества. - М. : Химия, 1974, с. 315-325). Недостатком способа является длительность процесса, значительные потери свинца, большие эксплуатационные затраты. Для получения раствора свинцовой соли используют чистый металлический свинец. Последний производят пирометаллургическими способами из сульфидных или сульфидно-окисленных свинцовых концентратов по многоступенчатым технологическим схемам. A known method of producing a solution of lead salt for the production of lead crowns and other chemical compounds (Karyakin Yu.V., Angelov II. Pure chemicals. - M.: Chemistry, 1974, S. 315-325). The disadvantage of this method is the duration of the process, significant losses of lead, high operating costs. Pure metallic lead is used to produce a solution of lead salt. The latter is produced by pyrometallurgical methods from sulfide or sulfide-oxidized lead concentrates according to multistage technological schemes.
Наиболее близким способом является способ для производства раствора свинцовой соли с использованием свинцово-сурьмяного сплава (патент-заявка 96112494/25, С 01 G 21/18, С 09 С 1/20, БИ 27, 1998, с. 100. Способ получения раствора свинцовой соли, используемой при производстве свинцовых кронов). The closest method is a method for producing a solution of lead salt using a lead-antimony alloy (patent application 96112494/25, C 01 G 21/18, C 09 C 1/20, BI 27, 1998, p. 100. The method of obtaining the solution lead salt used in the production of lead crowns).
Сурьмяно-свинцовый сплав также получают пирометаллургическим способом из чернового свинца от переработки свинцово-сурьмяного концентрата. Пирометаллургические способы производства свинца или свинцово-сурьмяного сплава экологически опасны (выброс газов SO2-SO3, свинецсодержащих пылей, возгонов свинца, цинка, мышьяка и прочих ядовитых веществ) с потерями свинца более 6,2-8,9%. В целом технологическое производство получения растворов свинцовой соли состоит из двух технологических схем: технологии производства чистого свинца и технологии получения раствора свинцовой соли (см. чертеж).Antimony-lead alloy is also obtained by the pyrometallurgical method from crude lead from the processing of lead-antimony concentrate. Pyrometallurgical methods for the production of lead or lead-antimony alloy are environmentally hazardous (emission of SO 2 -SO 3 gases, lead dust, sublimates of lead, zinc, arsenic and other toxic substances) with lead losses of more than 6.2-8.9%. In general, the technological production of obtaining solutions of lead salt consists of two technological schemes: the technology for the production of pure lead and the technology for producing a solution of lead salt (see drawing).
Разработанный способ исключает необходимость производства чистого металлического свинца из сульфидного концентрата (см. чертеж). Способ осуществляется следующим образом. Свинец из свинцового концентрата растворяют в растворе азотной кислоты при температуре 65-75oС с получением азотнокислого раствора свинца состава: Pb=91; Zn=0,9; Fe=50 г/л; Со=2,3; Ni=17,2; Ca=22,5; Mn=190; Mg=1,6 мг/л, рН 2,1-0,5.The developed method eliminates the need for the production of pure metallic lead from sulfide concentrate (see drawing). The method is as follows. Lead from a lead concentrate is dissolved in a solution of nitric acid at a temperature of 65-75 o With obtaining nitric acid solution of lead composition: Pb = 91; Zn = 0.9; Fe = 50 g / l; Co = 2.3; Ni = 17.2; Ca = 22.5; Mn = 190; Mg = 1.6 mg / L, pH 2.1-0.5.
Методом селективного осаждения PbSO4 (введением Н2SO4-Na2SO4) проводится отделение свинца от примесей. Полученная чистая соль PbSO4 является исходным продуктом для синтеза других солей свинца. Из соли PbSO4 методом карбонизации составом [Na2СО3-Н2О-СО2] синтезируется соль РbСО3.The method of selective deposition of PbSO 4 (the introduction of H 2 SO 4 -Na 2 SO 4 ) is the separation of lead from impurities. The resulting pure salt of PbSO 4 is the starting material for the synthesis of other lead salts. The PbCO 3 salt is synthesized from the PbSO 4 salt by carbonation with the composition [Na 2 CO 3 -H 2 O-CO 2 ].
Пример 1. Example 1
Степень очистки раствора свинца от примесей в процессе осаждения PbSO4 зависит от рН суспензии (табл.1). Присутствующие в азотнокислом растворе примеси с различной степенью осаждаются в области рН 2,2 и менее (рН 2,1÷0,5). Оптимальными условиями разделения свинца и примесей установлено: при рН менее 1,5, при осаждении соли PbSO4 не осаждаются элементы примеси; с переходом в область рН>1,5 протекает осаждение примесей. Другие условия осаждения PbSO4 (время, температура процесса, перемешивание) не изменяют значения рН осаждения PbSO4.The degree of purification of the solution of lead from impurities during the deposition of PbSO 4 depends on the pH of the suspension (table 1). Impurities present in a nitric acid solution with various degrees of precipitation in the range of pH 2.2 and less (pH 2.1 ÷ 0.5). The optimal conditions for the separation of lead and impurities have been established: at pH less than 1.5, impurity elements do not precipitate during the precipitation of the PbSO 4 salt; with the transition to a pH range> 1.5, the deposition of impurities proceeds. Other conditions for the deposition of PbSO 4 (time, process temperature, stirring) do not change the pH of the deposition of PbSO 4 .
Пример 2. Example 2
Полученная соль PbSO4 является основой для синтеза РbСО3. Состав соли РbСО3 зависит от температуры, смеси подаваемого реагента для карбонизации PbSO4. Процесс проводится в суспензии (т:ж=1:1) введением смеси раствора Nа2СО3 100-200 г/л + CO2] или [Н2СО3 100-200 г/л + СO2] при температуре суспензии на уровне 50-60oС (оптимальный уровень) (табл.2). Полученный осадок после карбонизации представляет монофазу РbСО3 (отсутствуют другие соли).The resulting salt of PbSO 4 is the basis for the synthesis of PbCO 3 . The composition of the salt of PbCO 3 depends on temperature, the mixture of the supplied reagent for the carbonization of PbSO 4 . The process is carried out in suspension (t: W = 1: 1) by introducing a mixture of a solution of Na 2 CO 3 100-200 g / l + CO 2 ] or [H 2 CO 3 100-200 g / l + CO 2 ] at a temperature of the suspension level of 50-60 o C (optimal level) (table 2). The resulting precipitate after carbonization is a monophase of PbCO 3 (no other salts are present).
Пример 3. Example 3
Соль РbСО3 является исходным продуктом для синтеза других солей свинца. Соль РbСО3 растворяют в растворе азотной кислоты с получением раствора соли свинца Рb(NО3)3.Salt PbCO 3 is the starting material for the synthesis of other salts of lead. The PbCO 3 salt is dissolved in a solution of nitric acid to obtain a solution of the lead salt Pb (NO 3 ) 3 .
