Ball mill 80%

Meso-acidophilic bacterial leaching of ball mill spillage (containing chalcopyrite 80%) was carried out in an innovative two-step bioleaching method. The major drawback of meso-acidophilic bioleaching limiting industrial application is the passivation phenomenon over the ore surfaces in iron-sul
