Carbon fines gold recovery system the macrotec gold recovery from activated carbon system has revolutionised the way gold is recovered from fine activated carbon.The system has had global success, with units operating in south africa, tanzania, ghana, mali, and the usa, with projects underway in asia.The system utilises a thermal process that burns.
This process is known as carbon-in-pulp.The result is gold that is attached to carbon.The next step is to remove the gold from the carbon bonds.This is achieved by filtering and separating the gold-bearing carbon using screens.The carbon is stripped with a hot caustic solution, which separates away the gold.
South africa is one of africas most industrialised countries and has the continents second largest economy after nigeria.In the decades since apartheid ended in the early 1990s, its economy has more than tripled in size, but faltered in recent years.It currently ranks 32nd in the world.President cyril ramaphosa, leader of the governing african national congress party, was.
The final gold product of tau lekoa mine has a low fineness.This is caused by high concentration of bases metals in the reefs.Some of these base metals together with gold are leached with cyanide and are loaded into carbon.If not adequately controlled, they may elute with gold and contaminate the final product in the electrowinning process.
