Iron ore processing plant in China generally use the thick broken, broken and fine broken three sections of crushing flowsheets crushing ore. Thick broken multi use 1.2m or 1.5m gyratory crusher, broken using the 2.1m or 2.2m standard cone crusher, fine broken by 2.1m or 2.2m short head cone crusher.
The flowsheet above was designed to treat economically approximately 200 tons in 24 hours of a low-grade dump ore containing lead and zinc values as well as some silver in both sulphide and oxide form. Due to varying specific gravities of the values, gravity concentration in addition to flotation was indicated. As is common in many ... ="How to …
the well-known method for generally low grade gold ore treatment due to its relatively low capital and operating costs. Crushing the ore to an allowable upper limit is the only size reduction step. A good rule of thumb is to avoid crushing if at all possible. If necessary to select the crushing system with a proven capability (Kappes, 1979 ...
