Description
Известны способы извлечени металлов из сульфидных полиметаллических промпродуктов с применением хлорирующего обжига.Methods are known for recovering metals from sulphide polymetallic middlings with the use of chlorinating roasting.
Особенность предлагаемого способа в том, что обжиг провод т при температуре 400- 450° С в присутствии карналлита и угл , что дает возможпость селективно отгон ть в газовую фазу хлорид висмута, улавливаемый затем раствором соды.The peculiarity of the proposed method is that the calcination is carried out at a temperature of 400-450 ° C in the presence of carnallite and coal, which makes it possible to selectively distil bismuth chloride into the gas phase, which is then trapped by soda solution.
Висмутсодержащий сульфидный промпродукт смешивают с карналлитом и углем и обжигают в трубчатой печи при температуре 400-450° С.Bismuth-containing sulfide middlings are mixed with carnallite and coal and burned in a tube furnace at a temperature of 400-450 ° C.
В процессе обжига образуютс хлориды меди, цинка и висмута.During the burning process, copper, zinc and bismuth chlorides are formed.
Хлорид висмута, обладающий высокой упругостью паров, селективно отгон етс в газовую фазу на 90-92о/о, после чего улавливаетс 40%-ным раствором соды, в котором висмут осаждаетс в виде углекислой соли.Bismuth chloride, having a high vapor pressure, is selectively distilled into the gas phase at 90-92 o / o, after which it is captured by a 40% soda solution, in which bismuth precipitates as a carbonate salt.
Оптимальный расход карналлита, в присутствии угл в шнхте в пределах 3-5о/о, составл ет 10-15%, а без добавки угл - 60-70% от веса исходного продукта. Остаток от хлорирующего обжига, состо щий из хлоридов меди, цинка и свинца, с целью перевода хлоридов меди и цинка в раствор, выщелачивают водой, а полученный кек - раствором поваренной соли, с целью перевода хлорида свинца в раствор.The optimal consumption of carnallite, in the presence of coal in the range of 3–5 o / o, is 10–15%, and without the addition of coal, 60–70% of the weight of the original product. The remainder of the chlorinating roasting, consisting of copper, zinc and lead chlorides, with the purpose of converting copper and zinc chlorides into solution, is leached with water, and the resulting cake with solution of sodium chloride, with the goal of translating lead chloride into solution.
Из растворов металлы выдел ют известнымн методами.Metals are isolated from solutions by known methods.
Предмет изобретени Subject invention
Способ извлечени висмута из сульфидных промпродуктов путем хлорирующего обжига, отличающийс тем, что, с целью селективной отгонки висмута, обжиг провод т при температуре 400-450° С в присутствии карналлита и угл , а хлорид висмута улавливают раствором соды.A method of extracting bismuth from sulphide middlings by chlorinating roasting, characterized in that, in order to selectively distill off bismuth, roasting is carried out at a temperature of 400-450 ° C in the presence of carnallite and coal, and bismuth chloride is captured by soda solution.
