The Constancia deposit is a porphyry copper molybdenum system with copper bearing skarn mineralisation dominated by a sequence of sandstones mudstones and micritic limestone of the Cretaceous age intruded by multiple phases of monzonites and monzonite porphyry The ground ore is fed into the copper flotation circuit to produce a copper.Current operation (2003) is to blend 80 porphyry with 20 skarn ores resulting in an acceptable concentrate grade and recovery However when the proportion of skarn ore in the plant feed exceeds 20 low flotation recovery is often observed Approximately 20 of the copper and 30 gold losses occur through the rougher flotation circuit.
