Talc is a naturally hydrophobic gangue mineral in most sulfide ores. However, talc has vast applications in the cosmetics, paper, and paint industries due to its high chemical stability, and its demand continues to grow. Since flotation is the most effective beneficiation technique for upgrading sulfides, the high hydrophobicity of talc has made its selective separation challenging.

Processing of talc Boulos et. al. (2004) have applied the wet attritioning technique as a substitution of the conventional ball or rod milling in talc benefici ation plants because of the friable nature of talc. The objective of this process was to achieve preconcentration of talc by differential grinding from harder carbonate impurities.

Mineral processing faces intrinsically complicated processes and recirculating loads. Production can often be disturbed by unexpected events and recurrent maintenance operations. Today's mines must also process more complex ores due to declining ore grades. All of this adds up to complicated process operations. We can provide a better way.

The ball milling process was carried out in a Fritsch Pulverisette 6 planetary mono mill. The olivine basalt was subjected to wet milling in an 80 mL tungsten carbide bowl using deionized H 2 O or ethanol as process control agent (PCA). The balltopowder mass ratio was 20:1 w/w, the fluidtopowder mass ratio 1:10 or 1:2 and the rotation speed 300 rpm.
