2014-8-27 · It Vol.8, No.5 Characterisation and Pre-concentration of Chromite 371 may be seen that the 250 micron size fraction contained 32.5% by weight and assayed 10.3% Cr2O3. Whereas less than 25 micron size fraction contains 11.67% Cr2O3 with maximum Fe(T) i.e 33.16%.
2016-11-15 · Figure 3 a shows triple junction point in a massive chromite ore. Due to gabbro intrusion the chromite ore has undergone severe brecciation that resulted in mylonitisation of the chromite fragments as shown in Fig. 3 b. Figure 3 c shows presence of anhedral chalcopyrite grain in the altered matrix of normal chromite.
