chrome ore grinding size analysis

chrome ore grinding size analysis

Concerning the particle size analysis results, the predominance of 10 m size fraction, which represents a least 25 percent in mass for all the tested samples, is to be noted (Figure 2). However, chrome assays (by atomic absorption) on the 11 m, 11-20 m and 20-38 m size fractions allow to

    The Magotteaux Mill®: investigating the effect of grinding

    Jul 01, 2004 These data indicated that when high chrome grinding media was substituted for forged media when grinding a refractory gold ore, the pulp chemistry shifted to more oxidising conditions. This shift was accompanied by a reduction in the EDTA extractable iron levels in the pulp, and an improvement in the flotation performance
