historic gold tailings dams in the Witwatersrand area of South Africa is being investigated. The objective is to recover uranium and residual gold from the tailings, as well as to oxidize the sulphides to eliminate long term environmental liabilities associated with acid
Gold is used in other South African industries such as refined gold and jewellery making. The industry creates employment in other industries. Gold mining has a role to play in the development of human resources (training) and infrastructure such as schools, colleges, clinics, roads and housing.
The first step in the process involves a mildregrind and mild acid leach of the tailings (pH to ) to dissolve up to 40% of the uranium. This uranium is recovered directly from the pulp by resin ReProcessing Gold Tailings in South Africa

South Africa dominated the world as the number one gold producer until 2009 when China took that position, and today South Africa ranks fifth after China, Australia, Russia, and the USA. According to Statistics South Africa (2009), South Africa still had about 30 years of production in the gold sector, a forecast that fluctuates based on the
Today, South Africa produces only % of the worlds gold. In South Africa, mining for gold typically involves methods like panning, sluicing, dredging, hard rock mining and byproduct mining. The most effective method used is hard rock mining, since reserves are typically encased in deep underground rock. Where is gold found in South Africa?

Gold of either % or % purity can be produced from intermediate process products having a wide range of gold contents. The process comprises oxidative leaching of the solid
#0183;#32;The largest gold find in history is in the Witwatersrand of South Africa. Discovered in 1886, it produced 25 percent of the worlds gold by 1899 and 40 percent by 1985. The discovery of the Witwatersrand deposit coincided with the discovery of the cyanidation process, which made it possible to recover gold values that had escaped both gravity concentration and amalgamation.
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

South Africa South Africa Gold mining: Prospectors established in 1886 the existence of a belt of goldbearing reefs 40 miles (60 km) wide centred on presentday Johannesburg. The rapid growth of the goldmining industry intensified processes
Since 1921, all gold produced in South Africa has been refined at the Rand Refinery (Adamson, 1972). To give the reader a complete picture of gold refining in South Africa, the historical development and all operations of the refinery are described in detail in this chapter, although some activities cannot strictly be defined as gold refining.
South Africas formal gold sector still churns out about 4 billion in revenue every year. Along with platinum, coal and iron ore, its an important part of the economy.
Removing the goldbearing rock from the ground is just the first step. 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.
Openpit gold mining also takes place in South Africa. This is a mining technique which excavates at the surface to extract ore. The mine is open to the surface for the duration of its life. surface rail or truck to the crushing and milling circuits where the process to extract the pure gold from the rock begins. Step 8
