Abstract

Изобретение относится к способу выщелачивания навального концентрата халькопиритового типа посредством водного раствора, содержащего серную кислоту, и подачи кислорода при атмосферном давлении и температуре от 75°С до температуры кипения раствора. Для данного способа характерно, что 80% размеров частиц концентрата, подаваемого в выщелачивание, находятся в диапазоне ниже 60-100 мкм, и концентрат выщелачивают водным раствором, концентрацию кислоты в котором регулируют так, что она составляет примерно 20-90 г/л.
