Abstract

Методът намира приложение в хидрометалургията. С него се повишава скоростта на микробното окисляване на минералите. По метода минерални съединения от руди или концентрати, представляващи субстрати за микроорганизми, се подлагат на биоокисление, разтваряне и разделяне. През първия етап рудата или концентратът се обработват с киселина в минимално количество, осигуряващо пълното и равномерно подкисляване на субстрата, неутрализирането на материала и средата за развитие на микроорганизмите. През втория етап се добавя микробен инокулат, който окислява полезните минерали и обогатява микробната флора на минералната руда. През третия етап спонтанно или принудително се отделя излишъкът от вода чрез изпаряване или дехидратиране във въздушен поток до постигане на достатъчно ниска равновесна влажност, осигуряваща получаването на твърдофазен биоокислен продукт, съдържащ колонии от микроорганизми. В четвъртия етап продуктите на биоокислението се разделят. 9 претенции, 35 фигури
