Advantages of process used to separate mineral ores from gangue

how lead is made material, used, processing, productlead is used to make bearings and ser, and it is important in rubber production and oil refining. lead production dates back at least 8, s. lead was used in egypt as early as 5, b.c. , and in the time of the pharaohs it was used in pottery glazes and asglossary of mining terms secmagnetic separation a process in which a magnetically susceptible mineral is separated from gangue minerals by applying a strong magnetic field; ores of iron are commonly treated in this way. magnetic susceptibility a measure of the degree to which a rock is attracted to a magnet.iron ore iron ores are rocks and minerals from which metallic iron can be economically extracted. the ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. the iron is usually found in the form of magnetite (fe 3 o 4, 72.4% fe), hematite (fe 2 o 3, 69.9% fe), goethite (feo(oh), 62.9% fe), limonite (feo(oh)·n(h 2 o), 55% fe) or siderite (fecodense medium separation an effective and robust preincluded a variety of mineral systems such as spodumene, sulphidebearing g ores, and complex preconcentration is a process of rejecting mass of gangue while ensuring recovery of valuable minerals prior to more intensive, downstream processing. these machines are used to process a very broad range of feed particle sizes, as coarse

The case of process used to separate mineral ores from gangue

mineral processing industrially, the most common dense media is a suspension of fine magnetite and/or ferrosilicon particles. an aqueous solution as a dense medium is used in coal processing in the form of a belknap wash and suspensions in air are used in waterdeficient areas, like areas of china, where sand is used to separate coal from the gangue minerals.class xii chemistry metallurgy yolaores the mineral from which the metals can be economically and conveniently extracted is called an ore. this is based on the differences in gravities of the ore and the gangue particles. in this process, an upward stream of running water is used to wash the powdered ore. magnetic particles form a separate heap near the magnetic roller.concentration of ore definition, types and properties of orethis method concentrates the ore by passing it through an upward stream of water whereby all the lighter particles of gangue are separated from the heavier metal ore. this is a type of gravity separation. magnetic separation this involves the use of magnetic properties of either the ore or the gangue to separate
