X) Изобретение относитс к металлургии благородных и цветных металлов и может быть использовано дл извлечени золота, серебра, меди и висмут из сульфидных руд и промпродуктов, а также в производстве указанных металлов. Цель изобретени - повышение степени извлечени благородных металлов и висмута.. Пример. Сульфидные промпродукты с содержанием 3,6% меди, 0,15% висмута, 7, золота и 45,5 г/т серебра обжигают в окислительной атмосфере при 550-600 С, из огарка раствором с концентрахщёй 5-10 г/л серной кислоты извлекают 92% меди. Полученный после удалени меди кек с содержанием 0,21% висмута, 10 г/т золота и 1 г/т серебра обрабатывают раствора№1 с концентрацией 4-6 г/л тиомочевины, 7 г/л серной кислоты. 6 г/л сульфата железаСШ) и 50250 г/л Хлорида натри . Продол оттельность обработки 10 ч, температура 25-50 0, отношение . Дл сравнени проведено выщелачивание благородных металлов и висмута из огарка, после удалени меди, в услови х известного способа. Полученные данные приведены в таблице . Таким образом, при введении в сернокислый раствор тиомочевины 100200 г/л хлорида натри извлечение золота повышаетс на 8-10%, серебра 10-11% , висмута - 20-25% в сравнении с результатами в услови х известного способа. Повышение содержани хлорида натри более 200 г/л не вли ет на извлечение металлов, при концентрации хлорида натри 100 г/л извлечение металлов уменьшаетс .X) The invention relates to the metallurgy of noble and non-ferrous metals and can be used to extract gold, silver, copper and bismuth from sulfide ores and middlings, as well as in the production of these metals. The purpose of the invention is to increase the degree of extraction of noble metals and bismuth. Example. Sulfide middlings with a content of 3.6% copper, 0.15% bismuth, 7, gold and 45.5 g / t of silver are calcined in an oxidizing atmosphere at 550-600 ° C, from the calcine with a solution with a concentration of 5-10 g / l of sulfuric acid extract 92% of copper. The copper cake obtained after removing copper with a content of 0.21% bismuth, 10 g / t gold and 1 g / t silver is treated with solution no. 1 with a concentration of 4-6 g / l thiourea, 7 g / l sulfuric acid. 6 g / l ferrous sulfate) and 50,250 g / l sodium chloride. Prolonged processing time 10 hours, temperature 25-50 0, ratio. For comparison, leaching of noble metals and bismuth from the calcine was carried out, after removal of copper, under conditions of a known method. The data obtained are shown in the table. Thus, when thiourea is added to 100,200 g / l of sodium chloride in a sulphate solution, gold recovery increases by 8-10%, silver 10-11%, bismuth - 20-25% in comparison with the results of the known method. An increase in the sodium chloride content of more than 200 g / l does not affect the recovery of metals; at a sodium chloride concentration of 100 g / l, the recovery of metals decreases.
