Cubic boron nitride is utilized for high speed grinding applications. Compared to diamond, cBN has the upper hand in these applications because of its chemical inertness. While diamond reacts with ferrous metals, cBN can maintain its inert nature up to K. Similarly, cBN is utilized in cutting operations.

1. Introduction. Nowadays, with the increasing depletion of high grade and coarsegrained ores, the trend is towards the extraction of lowgrade ores [1].This can have two consequences for the minerals industry; first to process larger tonnages of mineral raw material and second to grind the raw materials to finer sizes [2], which in turn leads to higher energy consumption.

Chapman et al. (2013) compared the effects of using different circuits HPGR (dry) rod mill (wet) and cone crusher (dry) rod mill (wet) on the flotation of base metal sulfides. They indicated that apart from the grinding environment, HPGR could produce finer particles than a cone crusher. This difference was higher in the fully dry system.

Remarkably, pure boron is a rare substance; boron tends to form refractory material containing small amounts of carbon or other elements. Several allotropes of boron exist: amorphous boron is a brown powder and crystalline boron is black, extremely hard (about on Mohs' scale), and a poor conductor at room temperature.
