2 Gold Mining in Sudan. Numerous archaeological studies have revealed that gold was a pillar of economy in ancient Nile Valley civilizations (Klemm & Klemm 2013). It has long been assumed that gold in ancient Egypt came from the south and was extracted largely, if not entirely, by the process of panning (Meyer et al. 2003).
South Africa began to slow down in the 1880s, as the new deposits being found tended to be pyritic ore and gold could not be extracted from this compound with any of the then available technologies. John Stewart MacArthur and the Dingus brothers overcame this by suspending the crushed ore in a cyanide solution.
