Description
ем осуществлени способа, так как сульфат-ион образуетс в процессе самого вы щелачивани . Предпочтительно в вьдиелачивагощий раствор вводить смесь сол ной и серной кислот, чтобы мольное отношение ионов водорода к меди составл ло (О, 15-0, 65) :1, При этом кислотность исходного раствора незначительно вли ет на скорость вый1елачивани , поско,пь:ку в ходе последнего величина водородного показател пульпы (рН) устанавливаетс в пределах 2,5-4,0 и остаетс на этом уровне до окончани процесса вследствие гидролиза сульфата меди с образованием ее основного сульфата. Разработанный способ применш г к переработке любых медных концентратов, но наиболее эффективен дл халькошфитовых . Выщелачивающий раствор может быть реци кулирован. Применение вместо хлор- или бромиона других галогенов оказалось нерациональным . При использовании иод-ионг1 сте пень превращени меди концентрата слишком низка ; фтор-ион обладает высокой агрессивностью. Пример 1. Навеску ЗОО г халь копирит овог о концентрата, содержащего 25,4% Си , выщелачивают в автоклаве с механическим перемешиванием (П 6ОО об/мин) при плотности пульпыThe method is implemented because the sulfate ion is formed during the alkalization process itself. Preferably, a mixture of hydrochloric and sulfuric acids is introduced into the extensible solution so that the molar ratio of hydrogen ions to copper is (O, 15-0, 65): 1. At the same time, the acidity of the initial solution does not significantly affect the rate of leaching; during the latter, the pH value of the pulp (pH) is in the range 2.5-4.0 and remains at this level until the end of the process due to hydrolysis of copper sulfate to form its basic sulfate. The developed method is applicable to the processing of any copper concentrates, but is most effective for the chaloshfit. The leach solution can be recycled. The use of other halogens instead of chloro or bromion turned out to be irrational. When using iodine, the degree of conversion of the copper concentrate is too low; fluoride ion is highly aggressive. Example 1. A portion of ZOO g chalum ovog o concentrate containing 25.4% of C, leached in an autoclave with mechanical stirring (P 6OO rpm) at a pulp density
Таблица т:ж 1:3, температуре 145-175 С, давлении кислорода около 14 атм. Галоген-ион ввод т в виде сол ной кислотрл, хлористого натри , хлористого кали или хлористого аммони . Обработку ведут в течение 2, 5 час. Результаты опытов приведены в табл. 1. Пример 2. Выщелачивание провод т в услови х примера 1. В качестве выщелачивающего раствора используют фильтрат предыдущего опыта, поддержива посто нную концентрацию хлора (17 г/л НС) добавками сол ной кислоты. Величина рН пульпы в каждом опыте стабилизируетс на уровне 2, 8-3,2. Результаты опытов приведены в табл. 2, Накоплени меди и сульфа-в-иона в растворе не наблюдаетс ; среднее извлечение серы в элементарную 78%, средн степень превращени меди 98, 2%. Пример 3. В услови х примера 1, вьвцелачивают концентрат состава, %: медь 28, 4; железо 26, .1, сера 30, 8. Выщелачивающий раствор содержит 16 г/л серной кислоты к 57 г/л брома. Вли ние иона брома на скорость выщелачивани показано в табл.З. Применение бром-иона более Еффек™ тивно; одна и та же степень превращени меди в присзггствии бром-иона достигаетс почти в 2 раза быстрее, чем в присутствии хлор-иона.Table T: W 1: 3, temperature 145-175 С, oxygen pressure about 14 atm. The halogen ion is introduced in the form of hydrochloric acid, sodium chloride, potassium chloride, or ammonium chloride. The treatment is carried out for 2, 5 hours. The results of the experiments are given in table. 1. Example 2. The leaching is carried out under the conditions of example 1. As a leach solution, the filtrate from the previous experiment is used, maintaining a constant chlorine concentration (17 g / l HC) with hydrochloric acid additives. The pH value of the pulp in each experiment stabilizes at a level of 2.8-3.2. The results of the experiments are given in table. 2, There is no accumulation of copper and sulfa-in-ion in the solution; average sulfur recovery to elemental 78%, average degree of copper conversion 98, 2%. Example 3. Under the conditions of example 1, the concentrate of the composition is expressed in excess of%, copper 28, 4; iron 26, .1, sulfur 30, 8. The leaching solution contains 16 g / l of sulfuric acid to 57 g / l of bromine. The effect of the bromine ion on the leaching rate is shown in Table 3. The use of bromine ion is more effective ™; the same degree of copper conversion in the bromine ion prune is almost 2 times faster than in the presence of chlorine ion.
