Flotation of Aladagˇ oxide lead–zinc ores Semantic

Abstract Oxide lead–zinc ore sample containing 10.17% Pb, 10.98% Zn, 57 g/t Ag and 164 g/t Cd was subjected to this experimental study and taken from Kayseri located in the foothills of the Aladag Mountains, Turkey. Preliminary flotation tests with the ore sample indicated that there was no selectivity in terms of zinc recovery; therefore studies were concentrated on producing lead concentrates.
