Abstract. Mining in southern Africa has a long pre-colonial history. Haematite mining in Swaziland can be traced back more than 40,000 years, iron smelting dates from 400 AD or earlier, and copper from 900 AD. The most iconic evidence for pre-colonial mining are the gold artefacts from Mapungubwe dated between 1220 and 1300 AD.

Smelting ( q.v.) is the process used in blast furnaces to reduce iron ores. Tin, copper, and lead ores are also smelted. This article was most recently revised and updated by Robert Curley. Smelting, process by which a metal is obtained, either as the element or as a simple compound, from its ore by heating beyond the melting point.
In the 70 year history of the Flash Smelting process for sulphide concentrates [2], significant equipment development was needed in the completely new smelting concept, and specifically the novel smelting furnace (FSF) and its key equipment. Already from beginning, the very low use of external fuel and a superb sulphur fixation were evident.
