An ore contains a metal associated with other undesired substances like sand, clay, etc. These undesired substances are collectively known as gangue (or) matrix. The process of separating gangue from an ore is known as concentration of the ore. It is also called dressing or benefaction. Metals can be concentrated from their ores using any of these methods hydraulic washing, magnetic separation, froth floatation

Physical separation processes, including blasting techniques, ore sorting, screening, magnetic separation, gravity separation, jigs, may be employed as pre-concentration techniques. Depending on the mineral and specific characteristics of the ore body, a tailored pre-concentration flowsheet may use several devices to prepare the pre-concentrate with the best liberation properties.

Metal extraction from ores occurs in many different ways involving physical, chemical and electrical means. Even ores of the same metal sometimes require different methods of separation depending on the concentration of the metal and its chemical composition within the ore. Ores are naturally occurring sources of metal.

Geochemical exploration relies on the fact that metals in ore deposits will undergo dispersion by weathering, erosion and transport processes. A geochemical anomaly is a concentration of metal above its normal background value. A dispersion occurs when small amounts of metals are spread out around the ore deposit by surface processes.

ores are processed directly to impure black copper ( 95 wt % Cu) and to a copper-rich slag. The two ore types can be smelted together to produce matte and a slag with low copper content. Another product is top gas, which contains flue dust. Ores that contain high concentrations of arsenic and antimony also form speiss, which is difficult to decompose.

Feb 17, 2018In froth floatation process, advantage is taken of prefferential wetting of ore particles by oil and gangue particles by water. Pine oil or eucalyptus oil has tendency to wet metal sulphides. Thus sulphide ore is present in oily froth whereas gangue particles settle at the bottom,and hence fuller concentration is achieved.
