Atomised Ferro Silicon 15% is a specialised powder product formed by melting FeSi 75% with scrap and casting into a high-pressure water jet. Particle size is typically between 212 microns and 20 microns. The principal properties of FeSi 15% 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. FeSi powder creates different media densities and can be adjusted, within certain limits.
24 years experience of Atomised Ferro Silicon production and marketing. Unique quenching design on the atomiser produces some of the most spherical water atomised material available today. Our material has proven to have greater corrosion resistance, greater viscosity control, is more stable and recoverable and proven easier to achieve density than with most other water atomised materials.

Chrome is the twenty first most abundant element in the Earth's crust, its name is derived from the Greek word Chroma to mean colour due to the many colourful compounds made from it. Chrome does not occur free in nature, rather as the mineral Chromite. Chromite ore was first discovered in the Ural mountains of Russia in 1778 and chrome metal was subsequently isolated by Nicholas Louis Vauquelin in Paris, France in 1797. Initially it was incorrectly identified as being a lead compound due to its metallic red appearance. South Africa has 90% of the world's economic chrome reserves and produces over 50% of the world's Chromite. Other producers are Kazakhstan and India with increasing amounts being produced in Turkey.

Manganese is the twelfth most abundant metal found within the Earth's crust and derives its name from the Latin word Magnes which means Magnet. It is the fourth most used metal in terms of quantity behind iron, aluminium and copper. It was first used in the steel industry in Ancient Greece, the presence of manganese in the iron ore is most likely the reason that the weapons made by the Spartans were superior to their enemies. It was first isolated and recognised as an element in 1771 by a Swedish chemist called Scheele.
