Zamak 4 was developed for the Asian markets to reduce the effects
of die soldering while maintaining the ductility of zamak 3. This
was achieved by using half the amount of copper from the zamak 5

Roasting & Sintering
Over 95% of the world’s zinc is produced from zinc blende (ZnS).
Apart from zinc, the concentrate contains some 25-30% or more
sulfur as well as different amounts of iron, lead and silver and
other minerals. Before metallic zinc can be recovered, by using
either hydrometallurgical or pyrometallurgical techniques, sulfur
in the concentrate must be removed, which is done by roasting or
sintering. The concentrate is brought to a temperature of more than
900°C where zinc sulfide (ZnS) converts into the more active zinc
oxide (ZnO). At the same time sulfur reacts with oxygen giving out
sulfur dioxide which subsequently is converted to sulfuric acid –
an important commercial by-product.
80% of zinc mines are located underground, 8% are of the open pit
type, with the remainder a combination of both. In terms of
production volume, underground mines account for as much as 64% of
overall zinc production, combined underground/open pit mines
provide 21%, and the remaining 15% is sourced from open pit mines.
