Depositional environment The original control on gold
SYNOPSIS. Methods for treating and processing refractory gold ores are well established. However, what is less well understood is how the formation of the gold-bearing deposits affects gold processing and extraction. In order to evaluate the effect of ore genesis on gold extraction a number of South African gold deposits were studied.the mines of the Gold Fields Group in South Africa as a pilot unit for the evaluation of the sortability of various gold and other ores. Early in 1972, an order was secured from the Doornfontein Gold Mining Com-pany Limited, another of the Gold *This paper is also being published by the Society of Mining Engineers of the American Institute ofPhotometric sorting of ore on a South African gold mine

THE AUTOMATION OF THE ‘MAKING SAFE’ PROCESS IN SOUTH AFRICAN
Underground mining is the art of extracting minerals from deep within the earth‟s crust [1]. South Africa is a major mining country which boasts reserves in gold and platinum, these minerals require mining at very deep levels. This is known as hard rock mining and it is carried out in narrow tabular ore-bodies with mining heights less than 1.5 m.However, according to South African History Online, these were minor reefs and credit for the discovery of the main reef on Langlaagte Farm went to Australian George Harrison in July 1886.
