In South Africa zirconium is mainly sourced from mineral sands deposits. The ROM is processed via numerous stages of gravity concentration, magnetic separation and electrostatic separation. The zirconium is produced as a zircon product. The zircon is a feedstock for ceramics production and for zirconium metal production.

Electrostatic Discharge Varnish is an insoluble film deposit that forms on surfaces inside fluid systems, including pipes, tanks, bearings, heat-exchangers, and servo-valves. These deposits can cause operation problems, clogging valves and coating bearings to make them less effective and ultimately to fail.

Legal separation does not exist as a common law in South Africa. As such, it has no legal status. Under the laws of South Africa, one can either be Unmarried Married or Divorced. Generally speaking, the process of applying for a legal separation follows a similar procedure as filing for a divorce.
Beneficiation of phosphate ores by electrostatic processes has been demonstrated by various researchers since the 1940s. Separations have been achieved by removing silica from phosphates, and with fewer examples of calcite and dolomite from phosphate. Limitations on conventional electrostatic systems include low capacity, the need for multiple stages, and operational problems caused by fines.
