Stoichiometric mixtures of ZnS + Al and ZnS + Mg were milled for different times in a planetary ball mill. The XRD traces of the as-milled samples showed the presence of zinc, MgZn 2, and MgS after 30-min milling in the ZnS–Mg system.The traces of MgZn 2 disappeared after 1-h milling and the reduction reaction seemed to have been completed after 5-h milling.

Ball milling is effective in shortening the reaction time as the grain refinement of the GIS phase, as shown in Figure 5a–d. The highest HGR (HGR) occurs in advance and with a higher value versus the crushing powder. The HGR reaches over 4000 mL·min −1 for both ball milling alloy powders with NiCl 2 as shown in Figure 6a,c and Table 3.

After ball milling, the diffraction peak width increases due to the grain refinement of the mixed powder, as shown in Fig. 7(2/4). Ball milling makes the lattice distortion of CuSn10 alloy produce dislocation and other defects. On the one hand, Bi or FeS solid solution in the CuSn10 alloy causes the diffraction peak of the CuSn10 alloy to decrease.

Ball milling of rye bran gave rise to similar results, with the A/X ratio of the extractable AX being considerably lower (0.51). Optimization of the ball mill treatment by varying the degree of filling of the milling jar permitted us to obtain equally high WE-AX levels (>70%) in wheat and rye bran within a 24 h ball-milling period.
