Dissolution and reduction of chromite ore in ferrochromium

chromite ore was fed into the molten slag, and was followed by reduction of iron and chromium oxides. Due to the fact that the chromite ore was fed in granular form, as expected, a greater contact area was created which influenced the dissolution / reduction reaction between the ore and the slag. The slag composition played a significant role
