Grinding Process Grinding is a surface finishing operation where very thin layer of material is removed in the form of dust particles. Thickness of material removed is in range of 0.25 to 0.50 mm. Tool used is a abrasive wheel Grinding machine is a power operated machine tool where, the work piece is fed

The grinding fineness should mainly range between 30 and 75 μm. Ore sample flotation test. The grinding time, costs and total beneficiation cost increased. Besides, the grinding fineness was closely related to the beneficiation indexes. According to the analysis results shown in Fig. 5, the grinding process was developed, as shown in Table 6.
