The first step in the processing of beryl ore is normally hand-sorting to select beryl crystals containing at least 10% beryllium oxide (Ballance et al., 1978) on the basis of shape and colour (Powers, 1991). Two commercial methods have been used to process beryl to beryllium hydroxide: the fluoride process and the sulfate process.
