Mineral Processing. If the mineralogy of the ore shows that you can separate discrete particles of the mineral you want from the gangue components of the ore, then it is possible to physically concentrate the valuable mineral and reject the rest. The easiest method for achieving this is by gravity separation.

Mineral Processing - an overview | ScienceDirect Topics

Mineral processing or mineral beneficiation or upgradation involves handling of three primary types of ROM ore material which has been blasted, fragmented and brought out from in situ position. These materials can be used directly or by simple or complex processing and even applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.

Ore Sorting Strategies In Mineral Processing

For successful mineral processing design it's critical to evaluate the possibility of preconcentration or waste diversion before grinding. Mess up this step and you could be hit with avoidable downstream CAPEX and OPEX costs. At its core, preconcentration means exploiting particle differences as early as possible so that waste material isn't unnecessarily fed to the mill and then deposited ...

Processing, smelting and refining gold | World Gold Council

The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.
