Sep 25, 2010 Sep 25, 2010 Then, as grinding process of homogeneous ore follows a first-order kinetics, the slope of the line fitted to data points indicates the selection function. Fig. 9 shows how the data approximates to a first-order kinetics for the same.

Grinding Kinetics of VanadiumTitanium Magnetite

Grinding Kinetics Of Vanadiumtitanium Magnetite

Mar 21, 2016 The grinding behavior of the as-received 5 pct moisture vanadium-titanium magnetite concentrates in a damp mill was investigated in this paper. A grinding kinetics equation was established based on a population balance model using size distribution data obtained from a laser diffraction technique. X-ray diffraction results show that a loss in crystallinity occurs when the grinding time is ...
