The product of the existing grinding circuit at the Sukinda chromite ore beneficiation (COB) plant contains about 3040% ultrafine particle (<45 m). The generation of ultrafines adversely affects the efficiency (higher specific power consumption, losses of ultrafine chromite in the tailing, etc.) of the beneficiation circuit.

Thus, the added oleic acid played the role of a grinding aid for the effective milling of ZrH2. Similar phenomena were observed in mineral ball milling processes [20], cement raw material milling [21], and in the preparation of ultrafine functional materials by ball milling [22], in which surfactants were employed as grinding aids to enhance the milling efficiency and reduce production costs.

The small liberation sizes in the lowgrade ores require fine grinding which is an energy intensive operation. In the present study, lowgrade chromite ore bearing platinum group of elements (PGE) was used as an experimental material. The previous study concluded the liberation size of around 150 µm for chromite ore bearing PGE minerals.
