This copper recovery is comparable to the elutriation-type CPF (67% vs 65%) however, the mass pull was significantly lower for the NovaCell™ (9% vs 25%). A comparison flowsheet of the two different CPF technologies is shown in Error! Reference s ource not found. and Error! Reference source not found.. The downstream impact is significant, while both technologies achieve comparable copper recovery, the NovaCell™ achieves a three-fold reduction in product mass pull compared to the elutriation-type CPF (3% vs 10%). This demonstrates the significant downstream benefits of the NovaCell™, particularly in reducing the need for capital-intensive modifications to cleaner flowsheets and additional regrind mill power.
