By 2000 bc the process of purifying goldsilver 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 immense amounts of manpower. By ad 100, up to 40,000 slaves were employed in gold mining in Spain.

Gold mining in South Africa peaked in the 1980s and mine closure in the Johannesburg area was a gradual process stretching over decades (in the late 1900s) as different mines closed down based on their profitability (Winde and Stoch, 2010). These mine closures in the Central, East and West Rand have not had a significant impact on the local ...
Introduction The African continent is richly endowed with significant mineral, oil and gas resources, including large reserves of gold. As noted in the previous chapter, the continent is home to a large portion of the world's mineral wealth, including 42 per cent of the world's known gold reserves (Bush, 2008, p. 361).
The Golden History of South Africa. South Africa's history with gold mining dates back to the late 19th century, with the discovery of gold in the Witwatersrand Basin. This discovery led to the Witwatersrand Gold Rush, transforming the region's economic landscape and positioning South Africa as one of the world's leading gold producers.
The gold mining industry has played a significant role in the historical development of South Africa and continues to play an important role today, not only on a macroeconomic level but on local and community levels too. This is despite the country's gold mining production having declined in recent years.
Mining platinum in placer deposits is a relatively simple process. Dredges scoop the platinumbearing sand or gravel from riverbeds or mining pits. The material is washed until platinum grains or nuggets are captured and pulled from the surrounding material. Sperrylite, or platinum arsenide. Photo from Thomas A. Loomis, Dakota Matrix Minerals.
