Chamber of Mines (now Minerals Council South Africa) founded 1890 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.
