and high grades (5%-20% mineral sand content) with coarse-grained (>100 micrometre) mineral sand assemblages. In contrast, WIM-style deposits are sheet-like and up to 10 m thick, 10 km long and 3 km wide and are relatively high tonnage and low grade (2%-5% mineral sand content) with a fine-grained (<100 micrometre) mineral sand assemblage.
The heavy minerals have high average densities (of over 4.0 g cm −3) and are significantly heavier than the sand matrix (density 2.6 g cm −3). The large difference in the mineral densities can result in segregation of the heavy minerals during drilling and sample collection causing a biased composition of the recovered samples.
This report provides a descriptive model of heavy-mineral sands, which are sedimentary deposits of dense minerals that accumulate with sand, silt, and clay in coastal environments, locally forming economic concentrations of the heavy minerals. This deposit type is the main source of titanium feedstock for the titanium dioxide (TiO2) pigments …
Mineral resources are vast and the extensive African coastline offers significant exploration potential and possibly is the largest depository of valuable heavy minerals (VHM) on the planet.
