Abstract
Anglo Base’s Namakwa Sands heavy mineral sands operation is located on the West Coast of South Africa. Heavy<br>minerals are extracted from paleo-beach sands, but in certain areas of the deposit relative hard calcretised or<br>silcretised horizons occur. Although this material is mineralised, it is discarded to waste as the current plants are<br>not equipped to liberate mineral from the hard layers. It has become essential to determine the amount of hard<br>material in the ore body to justify the construction of a new plant for treating the hard material.
