Tungsten processing, preparation of the ore for use in various products.. Tungsten exhibits a body-centred cubic (bcc) crystal lattice. It has the highest melting point of all metals, 3,410° C (6,170° F), and it has high conductivity for electricity. Owing to this unique combination of properties, it is used extensively as filaments for incandescent lamps, as electric contacts, and as
Tungsten scrap is a very valuable raw material due to its high tungsten content in comparison to ore. Contaminated cemented carbide scrap, turnings, grindings and powder scrap are oxidized and chemically processed to APT in a way similar to that used for the processing of tungsten ores.
Algeria Algeria Mining: The main mining centres are at Ouenza and Djebel Onk near the eastern border with Tunisia and at El-Abed in the west. Extensive deposits of high-grade iron ore are worked at Ouenza, and major deposits of medium-grade ore exist at Gara Djebilet near Tindouf. Nearly all the high-grade iron ore from the open-cut works at Ouenza is used to supply the domestic steel
