WHILE resource estimations for mineral sands deposits – often approached simplistically – face many of the same challenges involved when estimating gold or iron ore deposits, there are others unique to mineral sands. Mineral sands projects often have a long history of ownership change due to market cycles, which means estimations need to include historic data sets, past drilling programs, assaying techniques and approaches to mineral assemblage determinations. Mineral sands deposits typically have wide drill-hole spacing, which can make domain determination a challenge. It is important to understand the underlying geology as much as possible, and capturing this and the distribution of grades through domaining is critical. The continuity of heavy mineral accumulations can often be very strong in the...

The tower mill was originally developed in Japan in the 1950s for fine grinding of copper in the mining sector and cutting garnet for polishing glass. Today it remains a proven and robust energy efficient wet grinding mill, combining both material separation and rapid size reduction in one piece of equipment. This is only possible in vertical agitated mills, which use an agitator screw to efficiently transfer energy to the grinding media. Finer material rises to the top of the vertical mill chamber and is carried out in the overflow slurry. The Nippon Eirich Group supplier  the Eirich TowerMill (ETM), which is available in sizes from 7 kilowatts to 1120kW of installed power. The ETM also processes between 0.5 and...
