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.

The transformation of boron nitride from the cubic to hexagonal phase has been investigated between 1560 and 1660 °C. Highpurity cBN powders of three different particle sizes (< μm, 24 μm and 3545 μm) were heat treated at ambient pressure in a dry flowing helium atmosphere over this temperature range for up to 8 h.

Figure 5. TEM images of purified powder pyrolyzed at 1600°C: a. B4C powder, b. SAD pattern and c. twin formation in powder. presence of free carbon in the pyrolyzed powder is possibly due to evaporation of more boronrich phases from the mixture during pyrolysis. The pyrolysis at 1600°C may be the optimum temperature for production of B4C powder

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.
