The mining of beach sands and of fossilized beach placers is often controversial because the operation requires the strip mining of large areas. Often this land is in ecologically sensitive surroundings and contains fragile ecosystems built up on poor sandy soils. The mining process is ideally modelled on the extraction operations underway in Australia, where the strip mining is followed by rehabilitation of the mined areas including intensive re-vegetation

Mineral sands mining . In our mineral sands extraction process we use both wet and dry mining techniques. Wet mining involves dredging mineral sands from beneath the surface of a specially created extraction pond, while dry mining utilizes conventional earth-moving equipment such as scrapers, trucks, and excavators to excavate the mineral sands deposit.

The Richards Bay Minerals (RBM) heavy mineral-rich sands coastal dune deposits (Tisand, Zulti North) extend parallel to the beach. Mining was started within the Tisand lease just north of Richards Bay. RBM is situated approximately 200 km north of Durban and 20 km northeast of Richards Bay on the east coast of South Africa.

Heavy mineral sands are natural sedimentary deposits containing economic quantities of rutile, ilmenite, zircon, monazite, and xenotime. These heavy minerals are sources for pigments, high-grade titanium feedstock, glazes, industrial additives, and even abrasives. Heavy mineral sands are being explored as sources of rare earth elements like lanthanum (La), erbium (Er), cerium
