Precious Metal Recovery Methods

In slurry systems, there is a general trend towards the use of carbon-in-leach (CIL) as opposed to leaching and carbon-in-pulp (CIP). This is still a matter of debate in the industry, but many plants which have used CIL have found that lower capital costs from fewer slurry tanks more than offset additional carbon handling as a result of lower ...

Kyrgyzstan 4000tpd Gold Carbon-in-Pulp Processing Plant ...

After 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.
