Research of iron ore grinding in a vertical-roller-mill
For the grinding tests, a Loesche mill LM4.5 (table diameter 0.45 m) is used (Fig. 2a). This pilot scale mill is a special development for ore grinding, which is reflected by several features. The mill has four rollers, which are able to stress the particle bed with grinding pressures of up to 5000 kN/m 2. Various different roller geometries ...
2ZnS 3O 2ZnO SO2 (1)
Zinc ores typically may contain from 3 to 11 percent zinc, along with cadmium, copper, lead, silver, and iron. Beneficiation, or the concentration of the zinc in the recovered ore, is accomplished at or near the mine by crushing, grinding, and flotation process. Once concentrated, the zinc ore is
