We will focus on the important aspect of mechanical activation by grinding in a mill, namely, nanoscale wear of the treated substances and of the milling tools. A new technology called abrasive-reactive wear has been developed that utilizes wear debris as an integral component of the reaction system rather than treating it as a harmful impurity. This technology is applied to the processing of low-grade diamond and silicon by cupric milling tools. Abnormal influence of graphite on abrasive wear degree is established.
