At present, we can use the flotation process to recover the chromite with fine grain size (-100um) after the gravity separation. The results show that Mg2+ and Ca2+ can inhibit the chromium ore, and the inhibition of Mg2+ is influenced by the type of anions in the slurry. Therefore, after knowing the cationic behavior in the pulp, we can choose the appropriate pulp PH value, reagents concentration, add thechromium ore dressing process in papua new guinea,chromium ore dressing process in papua new guinea.
