Dependence on low-grade and refractory ores has increased globally and will continue to increase in the near future because of the rapid depletion of high-grade gold ores [1-3]. Besides the low grade, among these refractory gold ores, gold are contained in different gold-carrier, such as gangue, pyrite, native gold, fissure gold and ect.

In spite of the lack of basic research on flotation of gold-bearing ores, the flotation technique is used not only for upgrading of low-grade gold ore for further treatment, but also for beneficiation and separation of difficult-to-treat gold ores. This chapter focuses on treatment methods for gold-bearing ores.

The application of high-power electromagnetic pulses (HPEMP) irradiation in dressing of resistant gold-containing ores appears attractive as this technique provides for a significant increase in precious metal recovery (30–80% for gold and 20–50% for silver), therewith helping reduce both energy consumption and the cost of products

22.4: Beneficiation. Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue. The latter can be suspended in a stream of ...
