ABSTRACT

The largest applications for metallic antimony are as alloying material for lead and tin and for lead antimony plates in lead-acid batteries. Cadmium has a low melting point, is a divalent metal which forms complex compounds and is characteristically soft, malleable and ductile. In order to extract cobalt several methods have been developed to separate the cobalt metal from copper and nickel. Hafnium is a corrosion-resistant metal which is chemically similar to zirconium in whose minerals it is found. Iron is a metal which occurs in elemental form in the absence of oxygen. The lead metal is produced by the reduction of the lead oxide from the roasting process in a coke-fired furnace where it settles at the bottom. Magnesium is an alkaline earth metal which only occurs naturally in combination with other elements. Mercury is a heavy liquid metal at standard conditions of temperature and pressure.
