Abstract

В настоящее время многие зарубежные предприятия перерабатывают руды золота, содержащие значительные количества меди, растворимой в цианидном процессе. При использовании этой технологии применительно к переработке медно-золотых руд возникают сложности, обусловленные различным поведением медных минералов при растворении. Для предотвращения попадания цианидных соединений меди в хвостовые отвалы обычно используют методы разрушения этих соединений, что наряду с избыточным расходованием цианида при образовании соединений с медью приводит к значительным финансовым затратам. Поэтому экономически и экологически актуальны технологии, позволяющие при цианировании получать медь в качестве побочного продукта и обеспечивать оборот цианида. Такими технологиями, частично используемыми в промышленном масштабе, являются SART/AVR, Activox, CESL, Dynatec, Albion, Biocop, Platsol, Intec, Vitrokele, Hydrocopper, а также процессы, основанные на угольной и ионообменной адсорбции, жидкостной экстракции и др. В данном обзоре критически рассмотрены эти технологии и процессы, проведено их сравнение, отмечены достоинства и недостатки (ограничения применения), а также способы разделения меди и золота, меди и цианида.
