Magnetic Separation

Our ferromagnetic wet drum separators can be used in iron ore separation plants in both rougher or cleaner beneficiation appliions. We also provide demagnetising solutions that reverse the residual effects that magnetic separation has on the magnetic viscosity of ferrous slurries, to return the mineral stream to an acceptable viscosity for downstream processing.

Fundamentals of the Heat Treating of Steel

sidered to be the abundance of iron ore (iron is the principal ingredient in all steels) and/or the ease by which it can be reﬁned from ore. Neither of these is necessarily correct; iron is by no means the most abundant element, and it is not the easiest metal to produce from ore. Copper, for example, exists as nearly pure metal in certain parts of the world. Steel is such an important ...
