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

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.

AFX has had great success in these retrofit& 39;s particularly with a large Gold Plant in West Africa and a major Platinum plant in South Africa. IMPELLERS Mixing technology represents a balance between the requirements of the process and the output efficiency of the impeller within the process.
The pump-cell circuits were operated by moving all the carbon in a contactor every 2 days with carbon concentrations of 25–50 g/L. Typical upgrade ratios ratio of gold on loaded carbon to gold in feed at operating equilibrium was found to be 800–1000 for the cascade CIP circuit and 1800–2000 for the pump-cell circuits.
Today’s gold mining operations optimize efficiency and output through the use of superior Haycarb gold recovery carbon technology. Our high density carbons with particle to particle consistency in activity and shape is an ideal solution for appli ions in CIL carbon-in-leach CIP Carbon-in-pulp and CIC carbon-in-column processes.
The CIL process concentrates gold from 2.5–3.5 g/t in ore to 2000 to 6000 g/t on carbon. Although the earliest process was in South Africa in 1890 CIP/CIL was first introduced in gold processing in 1949 at San Andreas Honduras Marsden and House 2006 .
