Pelleting chromite ore/sodium carbonate mixes - at temps avoiding formation of decahydrate to improve pellet strength

The pellets are made by mixing the prepared ore with the Na2CO3 and feeding this to a pelletiser at >36 degrees C, pref. 40-100 degrees C, and then spraying in pre-heated water or an aq. soln. of Na2CO3 at >36 degrees C, pref. >40 degrees C. The pellets formed are then dried and roasted, th...

Summary:The pellets are made by mixing the prepared ore with the Na2CO3 and feeding this to a pelletiser at >36 degrees C, pref. 40-100 degrees C, and then spraying in pre-heated water or an aq. soln. of Na2CO3 at >36 degrees C, pref. >40 degrees C. The pellets formed are then dried and roasted, the absence of Na2CO3 10 H2O giving the pellets adequate green strength.
