Abstract

В настоящей заявке описывается способ извлечения ценных металлов из сульфидной руды, включающий стадии дробления руды в дробилке (14) первичного дробления до размеров кусков 40 см и менее, пропускание дробленой руды через один или более последующих процессов предварительного обогащения, таких как объемная сортировка (16) и просеивание (20) с последующей флотацией (46/50) крупных частиц, или гравитационным разделением, или магнитным разделением. Поток (54) отходов процесса/процессов предварительного обогащения с размерами частиц, превышающими 100 мкм, укладывают в отвал (26) и подвергают выщелачиванию в отвале. В этом интегрированном способе используется технология предварительного обогащения, наилучшим образом подходящая для характеристик конкретного рудного тела, причем в процессе предварительного обогащения одновременно образуется поток низкосортной руды, который дает существенно более высокий выход по сравнению с выходом, получаемым для обычного выщелачивания отвалов, содержащих добытую низкосортную руду.
