Abstract
Способ восстановления драгоценных металлов из углеродистой руды включает выщелачивание руды раствором выщелачивателя и концентрирование соединений драгоценного металла с выщелачивателем в растворе на природном углеродистом компоненте руды для последующего восстановления. Поглощающий объем природного углеродистого компонента руды может пополняться за счет добавления рециклированного углеродистого вещества или тонко измельченного углерода и смесь руды с выщелачивателем. После отделения углеродистого компонента руды от пустой породы материал пустой породы может обрабатываться с помощью процесса горячего добавления углерода в выщелачиватель для дальнейшего увеличения восстановления драгоценного металла.
