Raw Materials extraction
We get metal minerals, coal and limestone from mines around the world

In order to obtain pure metal we need to transport the iron cast with specials containers and oxidize the mix with pure O2
specials containers

Liquid metal is introduced into special moulds. Liquid metal fills the mould and get cold and rigid with a special shape.
