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.The invention relates to a method by which the pH-buffer capacity of the starting material directed to the selective flotation of copper is increased. Raising the pH buffer capacity is performed by supplying a basic soluble mineral along with ore to the pretreatment stage.
