Re-Processing Gold Tailings in South Africa

ABSTRACT The technical and economic feasibility or re-processing hundreds of millions of tons of tailings in a number of 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

Economic Impacts of Gold Production in South Africa

2011-8-6  South Africa Department of Minerals and Energy (2007). South Africa is estimated, by the US Geological Survey, to have 6000 metric tons of gold reserves. A full 95% of South Africa's gold mines are underground operations, reaching depths of over 2.5 miles. Coupled with declining grades, increased depth of mining, and a slide in the

By 2010, however, China affirmed its status as the world’s largest gold producer with production of 324 tonnes of gold, followed by Australia (222.8 tonnes), and South Africa with 219.8 tonnes. Today, South Africa produces only 4.2% of the world’s gold.

The gold and rounded pyrites from the conglomerates yield a rhenium-osmium isochron age of 3.03 ± 0.02 gigayears and an initial 187 Os/ 188 Os ratio of 0.1079 ± 0.0001. This age is older than that of the conglomerates.
