Nickel, cobalt and platinum group metals are key elements for materials processing. They occur together in one book because they (i) map together on the periodic table (ii) occur together in many ores and (iii) are natural partners for further materials processing and materials manufacturing. They all are, for example, important catalysts - with platinum group metals being especially important for reducing car and truck emissions. Stainless steels and CoNiFe airplane engine super alloys are examples of practical usage.Chromium Problems Concentrates made from UG2 ores contain considerable chromite, FeCr2O4. The melting point ... Circular and smaller rectangular furnaces with three carbon electrodes are also used (Warner et al., 2007). In all cases, theanbsp;...
