Chemical Use in Gold Mining How to Buy Gold Recovery Chemicals Camachem

Feb 24 2021In this way gold is recovered from the chemicals. nbsp The solution then becomes ready for electrowinning. In this process a strong electric current is made to pass through the solution from the positive and negative terminals of the container. This causes gold to collect on the negative side. In this way gold is recovered from the chemicals.
