    Mining industry of South Africa Wikipedia

    Diamond and gold discoveries played an important part in the growth of the early South African economy. A site northeast of Cape Town was discovered to have rich deposits of diamonds, and thousands of white and blacks rushed to the area of Kimberley in an attempt to profit from the discovery. The British later annexed the region of Griqualand West, an area which included the diamond fields. In 1868, the republic attempted to annex areas near newly discovered diamond fields, drawing protests from the nearby Briti

    Gold processing Britannica

    The gold was concentrated by washing away the lighter river sands with water, leaving behind the dense gold particles, which could then be further concentrated by melting. By 2000 bc the process of purifying gold-silver alloys with salt to remove the silver was developed. The mining of alluvial deposits and, later, lode or vein deposits required crushing prior to gold extraction, and this consumed

    These sand-like particles are combined with water to form a slurry to which additional chemicals cyanide and carbon are added to facilitate dissolving the gold and help with its extraction. The gold particles, extracted in this process, attach themselves to the carbon. The next step in the process involves stripping the carbon from the gold. Most companies retreat their slurry or 'tailings' for any remaining gold, uranium

    Extracting Gold HowStuffWorks

    To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls. In these drums, the ore is ground to a fine slurry or
