Изобретение относитс к гидро- металлургии олова и может быть использовано при переработке оловосодержащих сурьм нистых концентратов .The invention relates to tin hydrometallurgy and can be used in the processing of tin-containing antimony concentrates.
Цель изобретени - повьппение степени извлечени олова.The purpose of the invention is to increase the degree of extraction of tin.
Способ осуществл ют следующим образом.The method is carried out as follows.
Сурьм нистый концентрат вьпцелачивают в растворе, содержащем 200- 300 г/л хлористого натри и дополнительно сол ную кислоту, до концентрации хлор-иона 144-185 г/л при Т:Ж 1:(10-20), температуре 90- 95°С в течение 1,0 ч. Полученную пульпу фильтруют в гор чем виде, продуктами процесса вл ютс оловосодержащий раствор, направл емый на извлечение олова,и сурьм нистый концентрат,содержащий 45-48% Sb и 0,05-0,04% Sn.The antimony concentrate is concentrated in a solution containing 200-300 g / l of sodium chloride and additionally hydrochloric acid, up to a concentration of chlorine ion 144-185 g / l at T: W 1: (10-20), temperature 90- 95 ° C for 1.0 hour. The resulting slurry is filtered hot, the products of the process are a tin-containing solution directed to the extraction of tin, and antimony concentrate containing 45-48% Sb and 0.05-0.04% Sn .

После фильтрации пульпы в гор чем .виде и сушки полученного сурьм нистого кека последний содержит 0,05% олоёа и сурьмы.

After filtration of the pulp in the hot and the dried antimony cake obtained, the latter contains 0.05% of glue and antimony. Removing in a solution of tin 96.2%, antimony 0.08%, Data on the implementation of the method with different consumption of reagents are given in the table.

С увеличением концентрации в раст- воре хлор-иона свыше указанных пределов (опыты 7-9) нарушаетс селективность извлечени олова, в раствор одновременно переходит 0,3- 3,0% сурьмы. Кроме того, увеличение концентрации хлористого натри в растворе (более 300 г/л) приводит к образованию насыщенных растворов и создает трудности при обслуживании аппаратов.With increasing concentration in the chlorine ion solution above the indicated limits (experiments 7–9), the selectivity of tin extraction is disturbed, and 0.3 ± 3.0% antimony simultaneously passes into the solution. In addition, an increase in the concentration of sodium chloride in the solution (more than 300 g / l) leads to the formation of saturated solutions and creates difficulties in the maintenance of the apparatus.
При снижении в выщелачивающем растворе общей концентрации хлор-иона ниже 144 г/л (опыты 5,6) падает степень извлечени олова из сурьм нистого концентрата.With a decrease in the total concentration of chlorine ion in the leach solution below 144 g / l (experiments 5.6), the degree of extraction of tin from surfactant concentrate decreases.
