Wet Milling In Chromite Fines

2013). Chromite fines (typically 1mm) are wet milled together with a small percentage of a carbonaceous material that serves as an energy source during sintering. The grain size specification that must be obtained during milling is typically a d80 of 74 μm (80% passing size of 74 μm). Ceramic filters are used to dewater the milled slurry to a moisture

Apr 13, 1993 A carrier or piggy–back coagulation process was applied to improve the separation efficiency of chromite slimes in wet high–gradient magnetic separation. This was achieved by the addition of a coarse chromite fraction to the slime fraction ( 10 mm). Three coarse chromite fractions were investigated in the present study with size ranges

Wet milling experiments conducted suggested that Cr(VI) is not formed during such processes21. Although not published in the open scientific literature, it seems that the co-milling of carbon with the chromite ore also acts to significantly reduce the tendency for Cr(VI) generation during milling. If one therefore compares dry and wet milling
