Abstract

Изобретение относится к способу, посредством которого повышают рН-буферную емкость исходного материала, направляемого на селективную флотацию меди. Повышение рН-буферной емкости выполняют посредством подачи растворимого минерала основного характера наряду с рудой на стадию предварительной обработки.
