Abstract

Методът се използва за екстракция на цинк от сулфидни материали, съдържащи желязо и поне един от металите мед, олово и сребро. С него се осигурява по-висока степен на извличане на съдържащите се в изходната суровина метали и по-висока производителност. Изходният материал се подлага на перколационна екстракция в два етапа при температура 120-160'с, като през първия етап материалът се обработва със сернокисел разтвор, съдържащ и разтвора, получен през ii етап, при което съдържанието на цинк е в стехиометричен излишък. Полученият разтвор на цинков сулфид, съдържащ от 20 до 60 г/л свободна сярна киселина и не повече от 1 до 5 г/л тривалентно желязо, се сепарира от твърдия остатък, съдържащ сяра, цинк, мед, олово, сребро и желязо, като последното е под формата на сул фиди. Твърдият остатък се подлага на втора перколационна екстракция, като се контролира количество то на свободната сярна киселина така, че в края на процеса нейната концентрация в разтвора е от 35 до 160 г/л, а на тривалентното желязо 2-3 г/л. След филтруване разтворът се връща за обработване на нови порции материал през i етап. 5 претенции, 3 фигури
