Lead-Zinc ores

Marmatite concentrates have a lower zinc level due to dilution from the iron minerals. Separations are made possible by galena’s inherent natural hydrophobicity and due to the fact that sphalerite as a mineral is not easily collected by flotation reagents. The well established two stage sequential flotation

Reagents in calamine zinc ores flotation ScienceDirect

Feb 01, 2005· The concentrator operates different circuits for each ore type. The flotation of the willemite ore is performed with the following reagents scheme: pre-sulphidisation with sodium sulphide and flotation with primary amine as collector. The flotation feed is not deslimed and the circuit yields zinc grades of 44% and recovery levels of 87%.
