The concentration of Ore can define as the chemical process of eliminating impurities like sand, rocks, silt, grit etc. from the ore for the extraction of metal. In this content definition and methods for the concentration of ore are explained along with the definition of ore and its types.
The concentration of iron is often determined by atomic absorption spectroscopy, but sometimes it is important to know the concentrations of two different species of iron. Atomic absorption gives us only the total concentration of iron and no information on the oxidation state of the iron measure or the relations between two species of iron.
