What are the different types of metal ingredients?

Metal raw materials consist mainly of widespread types of minerals, although metals are also more and more derived from scrap, waste and recycled parts that are melted and sophisticated for metals that contain. Examples of the main mineral groups for metal raw materials include bauxite ore, a compound of aluminum hydroxides and aluminum oxides for aluminum and stiber ore, crystalline form of antimone sulphide, sb Antimony. Other widely used types of metal raw materials include iron ore, which is used to produce steel; Various oxidized forms of copper ore such as azurit, malachite and tennantite; and minerals such as sphalerite, from which it is derived from zinc. It is used as an economic means to support conflicts. This led to a government event, such as the US Reform Wall Street in the US in 2010 and the Consumer Protection Act for regulating the purchase of raw materials from some countries.Many metal raw materials from the Congo Democratic Republic, such as tungsten, Cassiterite and Coltan, are widely used to produce precious metals such as tin, tungsten and gold used in electronics and other industries.

Although many metal raw materials are widespread around the world, others such as platinum metal group are somewhat rare and are limited to limited regions such as Russia and South Africa, which are estimated to contain half of the world's reserves. The Platinum Metal Group is important in the production of drugs and organic chemicals and includes examples such as Platinum, Palladium and Iridium. Some of these important metals, such as platinum itself, which only come from mineral sperrylite, have no other source of minerals in nature.

Metal production also relies strongly on recycled metal raw materials. UN Environment Report (May 2011UN (UNEP) about the level of recycling at the end of life (EOL-RR) found that a group of 18 important metals had EOL-RR rates above 50% around the world. These were commonly used metals as zinc, nickel and chrome.

steel raw materials are one of the most important metals for a number of industries, although steel is generally recycled at a speed slightly above 50%. The most common recycled metal according to the UNEP report has been led since 2011, with a measure of almost 80% of the metal is obtained and re -used. Other widely recycled metal ingredients are preferred for both their clean value and for ubiquitous use, such as gold and silver for their value in jewelry and electronics, and aluminum and copper for their use in construction and transport.
