Chemische Bindung und Gitterenergie,mineral; sometimes the mineral may be first converted to a more amenable form. The procedure thus involves removal of remaining gangue, decomposition of the mineral if a compound, and agglomeration and collection of the metal. Extraction may be carried out in one or several stages.

They are mainly natural minerals in a fairly pure state, namely, fireclay (essentially kaolinite (A1.0..2SiO..2H.O) with excess silica or alumina), silica (in various forms), alumina, calcined magnesite and dolomite, chromite (Cr.O.. FeO) and graphite; although some are prepared synt

,Kugelpackungen mit besetzten Lücken,ly reducible oxidised minerals. The main economic minerals are hematite (Fe.O.), limonite (2Fe.O.. 3H.O), magnetite (Fe.O.) and siderite (FeCO.). Thus the production of iron by far exceeds that of aluminium, although the latter is actually more common in the earth’s crust.

Chemische Bindung und Gitterenergie,e may be a separate melting and alloying stage. In the cast iron foundry, the pigs cast at the blast furnace are remelted and any extra alloying carried out. Pure copper ingots for working are cast directly from the refining furnace. With copper for castings and other non-ferrous metals, usually the
