The process involves crushing manganese ore into smaller particles, sorted according to their size. Commonly used equipment includes ball mills, jaw crushers and vibrating screens. Grinding reduces the size of the ore and exposes more surface area, making it easier for chemical reactions to occur during subsequent processing.

Again, the milling unit also has a significant role in the beneficiation of tungsten-bearing ores. Li and Gao [89] reported that rod mill products possess better floatability than ball mill products. The work index of tungsten-bearing ores varies widely between 7 and 17 kWh/t according to the mineralogy of the host rock [177].
