Evaluation of graphite depressants in a poly-metallic ...

2017-3-1 · Synthetic dyes are commonly used for graphite depression in poly-metallic flotation circuits; however, these dyes can be very expensive. The aim of this study is to evaluate performance of certain low-cost alternative depressants for a complex lead-zinc (Pb-Zn) ore rich in graphite (Gr-C) on a conventional mini pilot-scale flotation circuit.
