Under the same conditions of mill rotary rate and charge ratio, the mixture of iron powder and quartz sand (Fe/SiO(2)) was found best in promoting the mirex destruction. Mirex was completed destroyed after 2 h grinding at a charge ratio of 36:1 (reagent/mirex, m/m) and a mill rotation speed of 550 rpm.
The destruction rates of mirex in five different feed-in mixtures for the ball milling experiments are shown in Fig. 1.In all cases, the contents of mirex consistently decreased with the extension of grinding time, and no mirex was detected after 8 h milling except using SiO 2 as reagent. However, significant differences can be found in the …

Laboratory batch wet ball milling tests of quartz and chlorite were carried out for four feed size fractions (− 2 + 1.19 mm, − 1.19 + 0.5 mm, − 0.5 + 0.25 mm,-0.25 + 0.15 mm). The results showed that both quartz and chlorite demonstrated the first-order breakage behavior in the feed size range investigated.
The mixture of DP, zero-valent metal (Al, Zn, besides Fe) and quartz sand (SiO 2) was subjected to grinding using a planetary ball mill in this paper. The best performance was obtained using Al and SiO 2 mixture, where the original DP was 99% degraded after 2.5 h milling.
