separation by flotation of copper lead zinc sulphides

Evaluation of graphite depressants in a polymetallic

Synthetic dyes are commonly used for graphite depression in polymetallic flotation circuits however, these dyes can be very expensive. The aim of this study is to evaluate performance of certain lowcost alternative depressants for a complex leadzinc (PbZn) ore rich in graphite (GrC) on a conventional mini pilotscale flotation circuit.
