Atomised Ferro Silicon 15 is a specialised powder product formed by melting FeSi75 with scrap and casting into a high pressure water jet. Particle size is typically between 212 microns and 20 microns. The principal properties of FeSi15%

are magnetism, corrosion resistance and density.

Atomised Ferro Silicon 15% is mixed in water to create a dense medium and finds uses in the mining and scrap processing industries. Dense medium separation is a gravity separation technique which creates a medium with a specific density.

This medium allows lights to float and heavies to sink, thus permitting separation due to density. The process typically

separates aluminium, magnesium and mixed heavy metals such as copper alloys, thereby increasing overall scrap

metal recycling rates. After sizing, the mixed feed is screened and then sent to a drum containing magnetite media

which removes the lower density waste (rubber, plastic, etc) and light metals such as magnesium alloys.

The heavy concentrated scrap is then directed to a second drum containing FeSi media which separates the aluminium

from other metals. These two media, namely Magnetite and FeSi, create different media densities and can be adjusted,

within certain limits.

Atomised Ferro Silicon 15% is usually supplied in big bags or in steel drums.
