Изобретение относитс к металлургии т желых цветных металлов и может быть использованд при комплексной переработке пиритных концентратов, содержащих медь и благородные металлы.The invention relates to the metallurgy of heavy non-ferrous metals and can be used for complex processing of pyrite concentrates containing copper and noble metals.
Цель изобретени - повьшение степени извлечени железа.The purpose of the invention is to increase the degree of iron recovery.
Пример 1. Медьсодержащий пиритный концентрат измельчают и под- вергают окислительному обжигу. Обжиг ведут до различного содержани сульфидной серы в огарке. Последующее сернокислотное выщелачивание провод т при 95°С, содержании серной кис- лоты 150 в течение 3 ч.Example 1. The copper-containing pyrite concentrate is crushed and subjected to oxidative roasting. Calcination is carried out to varying amounts of sulfide sulfur in the calcine. The subsequent sulfuric acid leaching is carried out at 95 ° C, the sulfuric acid content is 150 for 3 hours.
В таблице приведена зависимость извлечени железа в раствор в форме ферросульфата от содержани сульфида серы в огарке.The table shows the dependence of iron extraction into a solution in the form of ferrosulphate on the sulfur sulphide content in the calcine.
Пример 2. Огарок, полученны по способу, приведенному в примере 1 содержащий 11% сульфидной серы, выщелачивают раствором, содержащим 150 серной кислоты в течение 3 ч. При температурах процесса 50; 80; 90; 95 и 100°С в раствор переходит в форме ферросульфата 60; 97; 97; 97,5 и 97,5% железа соответст- венно.Example 2. A calcine obtained by the method described in example 1 containing 11% sulfide sulfur is leached with a solution containing 150 sulfuric acid for 3 hours. At process temperatures 50; 80; 90; 95 and 100 ° C in the solution goes in the form of ferrosulfate 60; 97; 97; 97.5 and 97.5% iron, respectively.
Пример 3. Огарок, по способу получени и содержанию сульфидной серы соответствующий приведенному в примере 2, вьпцелачивают серной кислотой при температуре 95°С в течение 3 ч. При концентрации серной кислоты 25; 100; 120; 150 и 200 кг-м в раствор переходит в форме ферросульфата 77; 97; 97; 97 и 97% железа соответственно .Example 3. The calcine, according to the method of preparation and the content of sulfide sulfur corresponding to that given in Example 2, is targeted with sulfuric acid at a temperature of 95 ° C for 3 hours. At a concentration of sulfuric acid of 25; 100; 120; 150 and 200 kg-m into the solution goes in the form of ferrosulfate 77; 97; 97; 97 and 97% iron, respectively.
Пример 4. Огарок, по способу получени и содержани сульфидной серы соответствующий приведенному в примере 2, выщелачивают серной кислотой концентрацией 150кГ М при температуре 95°С. При продолжительности выщелачивани 0,5; 2,5; 2,75; 3 и 5 ч в раствор переходит в форме ферросульфата 81; 96; 96; 97 и 97% железа соответственно.Example 4. The calcine, according to the method of obtaining and the content of sulfide sulfur corresponding to that given in Example 2, is leached with sulfuric acid with a concentration of 150 kg M at a temperature of 95 ° C. With a leaching time of 0.5; 2.5; 2.75; 3 and 5 h in the solution goes in the form of ferrosulfate 81; 96; 96; 97 and 97% iron, respectively.
Предлагаемый способ переработки пиритных концентратов позвол ет по сравнению с известным повысить степень извлечени железа в раствор.The proposed method of processing pyrite concentrates allows, in comparison with the known method, to increase the degree of iron extraction into the solution.
