The process design of gold leaching and carbon-in-pulp ...

2009-8-27  The carbon in the reactor into which pregnant pulp is fed (referred to as the first reactor) becomes highly loaded with gold. Loaded carbon values on operating plants range from 300 to 20 000 grams of gold per ton of carbon, a concen-trating factor of about 1 000–1 500. A portion of the loaded carbon is periodically removed from the first ...

Cyanide Leaching SGS South Africa

Activated carbon effectively removes the gold from the cyanide, as the gold is adsorbed into the pores in the carbon. This has spawned technologies such as CIP (carbon-in-pulp), CIL (carbon-in-leach) and CIC (carbon-in-columns). More recently, SGS has lead the gold processing industry with the development of resin-based technologies.

Carbon capture and storage in South Africa - ScienceDirect

2009-2-1  Consequently, South Africa is investigating the use of carbon capture and storage as a green-house gas emission mitigation measure. It has been shown that of the more than 400 million tonnes of carbon dioxide emitted per year, approximately 60% is sequestratable —that is, point sources and capturable. Of that, nearly 30 million tonnes per ...
