Platinum (element #78, symbol Pt) is a dense, silvery-gray metal. The platinum group of elements consists of metals with similar physical properties as platinum and these elements are among the rarest in the Earth's crust. They have high melting points, are dense or heavy and are non-reactive with other elements.
regarding taconite iron ore processing. Taconite mining and processing fall under the North American Industry Classification System (NAICS) 21221 Iron Ore Mining. According to the 1997 Economic Census of Manufacturing, in 1997, 32 establishments owned by 26 companies produced products that are categorized in NAICS 21221 (U.S. Department of
The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal traditionally has been a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the ...

An ironworks (or iron works) is an industrial plant for the production of steel from iron ores! Before the iron ores can be fed to the ironworks, they must first be mined (ore extraction) and specially processed for the blast furnace process (ore processing). These process steps are described in more detail in the following sections.
