The Effect of Water Flow Rate on Davis Tube Tests

Öz

The effect of water flow rate on Davis tube tests was investigated in different solid ratios using low and high magnetite content samples. It was found that with increasing water flow rate Fe recovery decreased for each studied solid rate. It has been shown that the chosen solid ratio does not affect the grade regardless of the water flow rate, it has an impact on the Fe recovery.
