In gold mining, activated carbon plays a pivotal role in two primary processes: carbon-in-pulp (CIP) and carbon-in-leach (CIL). These methods rely on the use of activated carbon to adsorb gold from ore slurries. The carbon acts as a reliable, selective collector of gold particles, contributing to high gold recovery rates.
