process of gravity separation of iron ore
Mineral processing metallurgy Britannica
Mineral processing Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of
Heavy Media Gravity Separation Mine Engineer.Com
Heavy Media Gravity Separation Heavy media gravity separation involves using a mixture of fine media material, such as magnetite (SG 5.1) or ferrosilicon (SG 6.8), suspended in a slurry of water, to produce a media slurry with a specific gravity that will allow low density material(s) to float, and other high density material(s) to sink.

All three project areas have been explored historically in the 1950's and 1960's, including sampling, drilling and metallurgical work to support the planning and development of iron mines.
Gold processing Britannica
Gold processing, preparation of the ore for use in various products. Native gold is the most common mineral of gold, accounting for about 80 percent of the metal in the Earths crust. It occasionally is found as nuggets as large as 12 millimetres (0.5 inch) in diameter, and on rare occasions
HYL Process for Direct Reduction of Iron Ore ispatguru
HYL Process for Direct Reduction of Iron Ore. HYL process is designed for the conversion of iron ore (pellet/lump ore) into metallic iron, by the use of reducing gases in a solid gas moving bed reactor.

Gravity Separation. 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 Lower grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high quality fine ore powders, are known as fines.. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals

Midrex Process for Direct Reduction of Iron Ore
Midrex Process for Direct Reduction of Iron Ore. Midrex is an ironmaking process, developed for the production of direct reduced iron (DRI). It is a gas based shaft furnace process is a solid state reduction process which reduces iron ore pellets or lump ore into DRI without their melting using reducing gas generally formed from natural gas.
The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide). Bauxite, the most important ore of aluminium, contains only 3060% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be purified before it can be refined to aluminium metal.
