Carbon-In
Carbon-in-pulp (CIP) is the sequential leach then absorption of gold from ore. During the CIP stage, pulp flows through several agitated tanks where sodium cyanide and oxygen have been added to dissolve gold into solution. In the absorption stage, this solution flows through several agitated tanks containing activated carbon.
اقرأ أكثرCarbon-In-Pulp With carbon-in-pulp, the ore is finely ground and the gold is solubilised using a cyanide leach in a series of tanks. The granular activated carbon is added to the leached slurry, where the carbon adsorbs the gold from the slurry solution and is then removed from the slurry by coarse screening.
اقرأ أكثرThe 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 ...
اقرأ أكثرThe pulp residence time is about one hour in each tank. The tanks are normally mechanically agitated and each will contain a batch of activate carbon for adsorption (generally 10-25grams of carbon per liter of pulp). The carbon size is 0.6-0.8mm. The actual gold adsorption rate could reach 95-99%. 5 Desorption and electrowinning

اقرأ أكثرGold CIP process eliminates the slurry washing and solid-liquid separation operations, directly uses granular activated carbon to absorb gold from pulp, and optimizes the traditional cyanidation gold extraction process, which simplifies the industrial production process, improves the leaching efficiency and reduces the production cost.
اقرأ أكثرAfter grinding, the slurry pulp was concentrated before leaching. In the leaching operation, the gold-bearing carbon was gained through absorption of the leached gold by activated carbon and fed to the desorption electrolysis system. The gold slime was smelted to produce crude gold ingots. The final product was qualified crude gold ingots.
