TiFe compound was produced by high-energy ball milling of TiH2 and Fe powders, followed by heating under vacuum. TiH2 was used instead of Ti in order to avoid the strong particles adhesion to grinding balls and vial walls. Mixtures of TiH2 and Fe powders were dry-milled in a planetary mill for times ranging from 5 to 40 hours. The amount of sample, number and diameter of the balls were kept

After mechanical activation (Ball milling) of copper–chromium catalyst, H 2 SO 4 leaching of copper followed by NaOH roasted leaching of chromium was carried out. This led to improve the maximum copper and chromium leaching yield up to 90% and ~82%, respectively. In consequences, the adopted activation approach was not found to be successful for quantitative extraction of both metals. In

By increasing milling time, chromium particles tend to break and homogeneous distribution of the average particle size is obtained. During the ball milling of copper composites, powder particles are severely deformed by the impact of the balls which cause an increase in the local temperature, and as a result, atomic diffusion occurs. Furthermore, the density of crystalline defects such as
