Grinding Circuit

The iron oxide crystal grains in most iron ores are not evenly distributed in size. Spiral separators can therefore be used to take out the coarser iron oxide grains in the primary grinding circuit to save grinding energy and help achieve a higher iron recovery.Figure 9.14 presents a typical flow sheet for processing an oxidized ore containing about 30% Fe using a combination of spiral and ...

Milling

Ball mills can be designed to operate continuously (fed at one end of the system and discharged at the other), or on a batch basis for smaller, or intermittent volumes. They can also be operated either on a stand-alone basis (‘open-circuit grinding’) or in conjunction with a classifier which returns oversize product to the mill for further grinding (‘closed-circuit grinding’).
