Gold/silver base metal concentrate deportment. Smelters typically pay >95% (Au) and 90% (Ag) in copper and lead concentrates, but will only pay 60-70% (maximum, depending on degree of Pb/Zn smelter integration) for gold and silver in zinc concentrates. Cost drivers are also important in flowsheet selection, and are summarised in Table 3.
