Brass is a part of our non-ferrous metal processing. Non-ferrous metals have quite extensive uses as their properties tend to be quite desirable: low weight, high conductivity, non-magnetic and corrosion resistance. Of the non-ferrous metals, copper is one of the most widely recycled, closely followed by zinc recycling.

Most people think of iron as a magnetic material. Iron is ferromagnetic (attracted to magnets), but only within a certain temperature range and other specific conditions. Iron is magnetic in its α form. The α form occurs below a special temperature called the Curie point, which is 770 °C. Iron is paramagnetic above this temperature and only ...

Magnetite is a mineral whose primary component is an iron oxide that contains equal amounts of iron (II) and iron (III). Its empirical formula is Fe 3 O 4, and it is often expressed as iron (II,III) oxide. In the past, it has been called ferrous-ferric oxide and triiron tetraoxide. Magnetite is found in igneous, metamorphic, and sedimentary rocks.
