Abstract

В настоящем изобретении предложен способ кучного выщелачивания с применением хлоридов для извлечения меди из первичного медного сульфидного минерала, при этом указанный минерал подвергают выщелачиванию в кислом хлоридном растворе или смешанном хлоридно-сульфатном растворе в присутствии кислорода при значении поверхностного потенциала минерала менее ниже 600 мВ (относительно н.в.э.) для перевода сульфида меди в раствор.
