• Carbon Regeneration Mineral Processing & Metallurgy

    Lower carbon activity will result in higher carbon inventories in the circuit, lower gold loadings on the carbon, and higher soluble gold losses from the circuit. The average carbon activity in a circuit is mainly a function of the efficiency of the carbon regeneration process (i.e.. not the activity of the new carbon).
