The present work addresses these challenges faced by the flotation process of complex sulfide ore of Mississippi Valley type with an insight into the froth stability and the flotation performance The first project in this study was aimed at finding the optimum conditions for the bulk flotation of galena (PbS) and chalcopyrite (CuFeS₂

Mitigation Of Environmental Hazards Of Sulfide Mineral

Today's major challenges facing the flotation of sulfide minerals involve constant variability in the ore composition environmental concerns water scarcity and inefficient plant performance The present work addresses these challenges faced by the flotation process of complex sulfide ore of Mississippi Valley type with an insight into the froth stability and the flotation performance

1 Froth Flotation – Fundamental Principles

Froth flotation can be adapted to a broad range of mineral separations as it is possible to use chemical treatments to selectively alter mineral surfaces so that they have the necessary properties for the separation It is currently in use for many diverse applications with a few examples being: separating sulfide minerals from silica gangue (and from other sulfide minerals) separating
