The Nuclear Fuels Corporation of South Africa (NUFCOR) started processing uranium as a byproduct of gold mining in 1967. Most of the uranium produced as a byproduct of gold mining is concentrated in the golf fields of the Witwatersrand area. Uranium is more easily and readily available than gold in South Africa.
CIL stands for carboninleach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks. CIL is slightly different from another gold extraction process called CIP or carboninpulp process.
