  • Mineral hardness effect on the combined mineral grinding

    The grinding behaviour of the majority of the feed samples was nonfirstorder due to the fast breakage rate of soft minerals and the low breakage rate of hard minerals in the feedCassiterite is heavy, hard, and extremely brittle; therefore, gravity separation was a frequently used method for recovering cassiterite [5,6] On the other hand, sulfide minerals are generally recovered by flotation Due to the different separation methods of cassiterite and sulfide minerals, the required grinding size is also different Minerals | Free FullText | Thermally Assisted Grinding ofSuch grinding of hard minerals helps to liberate more of the finely dispersed minerals of interest than vertical mills under comparable conditions It has been observed that the stress intensity created is distributed in four distinct zones [5] :Stirred Mills – Ultrafine Grinding ScienceDirect
