ore | National Geographic Society

Ore is a deposit in Earth's crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron.. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire.Copper is also used in construction. The process of separating a metal from its ore is known as smelting. Smelting is widely practiced today and has a long history dating back to the Bronze Age, when ancient peoples first learned the technique. Smelting methods range from the basic to the high-tech, and are applied to a variety of materials, including aluminum, iron and copper.

There are many methods of separation (concentration) of minerals: 1) Gravity separation. There are more than 12 types of gravity separation of minerals. It is used for the extraction of gold, coal, cassiterite, wolframite, rare earth mineral, niobium, zirconium, uranium minerals, and others. Read more . 2) Magnetic separation. There are more than 14 types of magnetic … The process of extracting a metal in pure form from its ore is known as metallurgy. The process of treatment depends on upon the nature of the ore, impurities, and the metal. From the extraction point of view, the metals can be broadly classified into five categories.

Extracting Tungsten from Wolframite Gold Ore

Straight gravity concentration of this ore, using the flowsheet shown, would result in a mixed gold-tungsten concentrate containing much sulphide which is not desirable for marketing. Consequently, it is evident that other concentration processes must be incorporated in the flowsheet to produce separate marketable concentrates of tungsten and gold. Gravity separation usually suffices to separate the ore. The metal is separated from the ore by heating in a reducing atmosphere to remove sulphides, etc. The final preparation of the metal is …

Flotation makes possible the processing of complex intergrown ores containing copper, lead, zinc, and pyrite into separate concentrates and tailings—an impossible task with gravity, magnetic, or electric separation methods. In the past, these metals were recoverable only with expensive metallurgical processes. Magnetic separation Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.
