Materials
that that are are mined or extracted extracted from from the Earth as opposed to materials that that are are extracted extracted from from previously used material material through recycling (See also Secondary Material) The The platinum group metals are are are six transition elements that are are are chemically very similar (palladium rhodium iridium osmium and and ruthenium) They are are are known for their purity high melting points and and unique catalytic properties Parliamentary Office of Science and Technology The use of high temperatures to extract and purify metals The The rare rare earth earth elements elements elements are are are are defined as the the the group of 17 elements elements elements that that include the the the 15 lanthanoids and and and scandium and and and and yttrium The The rare rare earth earth elements elements elements are are are are found in in in applications that that exploit their magnetic catalytic and and and optical properties Registration Evaluation Authorisation and Restriction of Chemicals A A European Regulation See See Rare Earth Elements See See also HRE LRE The process of taking a a a a a a a a a a a a a a a a a a a a raw raw material material and and transforming it into a a a a a a a a a a a a a a a a a a a a usable product Often there are many refining and and intermediate steps before a a a a a a a a a a a a a a a a a a raw raw material material reaches applications The economically mineable part of an Indicated Mineral Resource demonstrated by a a a a a a a a a a Preliminary Feasibility Study Resources in in in in in in the the context of of of minerals are a a a a a a a concentration of of of material of of of intrinsic economic interest in in in in in in or on on on on on the the earth's crust Scientific Advisory Group in Emergencies
Materials
that have been produced through the the the recycling of previously used materials materials rather than materials materials which are extracted from the earth Where powdered materials are coalesced into into a a a a a a a a a a a a a a solid or or porous mass through heating and sometimes compression without taking that material material into into a a a a a a a a a a a liquid phase An installation or or or or factory for smelting a a a a a metal from its ore Alloys based based on on Group VIIB elements capable of of of withstanding high high high temperatures high high high stresses and and and often highly oxidising atmospheres The three major classes of of of superalloy are nickel- iron- and and and cobalt based based alloys
