Flotation of Aladag oxide leadzinc ores ScienceDirect

The scope of this study was to recover oxide lead and zinc minerals from Alada Region (Kayseri Turkey) ores. Primary studies carried out with this ore have shown that flotation of oxidized lead and zinc minerals, in particular zinc minerals was difficult (Engin and 214;nal, 2003). In this paper, flotation properties of leadzinc minerals or possibilities of producing a concentrate by gravity concentration methods

Pyrite Activation in the Lead Zinc Tailings Recovery Xinhai

Most non ferrous metals are metal sulfides ores, such as lead zinc ore, copper sulfide, which often coexist with a large number of pyrites. Pyrite is the main raw material for industrial sulfuric acid, but China is a leading manufacturer and consumer of sulfuric acid, so the comprehensive utilization of pyrite plays an important role in lead zinc tailings recovery.

Tailings

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden , which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
