When the rocks are about 3/8-inch or smaller, they are fed as a slurry into the two ball mills. These mills contain literally hundreds of thousands of three-inch diameter steel balls that pulverize the ore until it is like fine sand or face powder. Only then are the copper minerals broken free of the rest of the rock to be separated by flotation
Mechanical milling was performed by using a planetary ball mill (PBM) under various experimental conditions. Copper powder (99.0% purity, median particle size x 50 = 45 μm, Aldrich chemistry) was used as shown in Fig. 1.Mechanical alloying (MA) was carried out at two types of rotation speeds: low (10, 50, and 100 rpm) and high (300, 500, and 700 rpm).
