Description of Milled Ferrosilicon 15%

Ferrosilicon 15%, also known as FeSi 15%, is suitable as Heavy Media for the Dense Medium Separation in the Mining Separation process. Dense medium separation is a well-established density separation process, ideally suited for the separation of minerals, ores, and metals. We have both Milled FerroSilicon 15% and Atomised FerroSilicon 15%.

Milled Ferrosilicon 15% is manufactured by melting ferrosilicon 75% and steel scrap in an induction furnace. The molten alloy is tapped into a sandbed, allowed to cool, and then broken into lumps, after which it is crushed in two stages and milled and air classified to the required size range.

Milled Ferrosilicon is available in 65D, 100D, 150D, 270D, and 270F products.

Specification of Milled Ferrosilicon 15%

Applications of Milled FeSi 15%

1. Milled Ferro Silicon 15# is a magnetic ferrosilicon produced in electric arc furnaces and subsequently milled to the size ranges required. In addition, Milled Ferro Silicon contains aluminum and titanium which enhances its resistance to corrosion.

2. Milled Ferro Silicon 15# is used in slurry density applications for heavy media separation and sink-float processes. Powdered Ferro Silicon is an accepted medium for the gravity separation of minerals, aggregates, and metals with a specific gravity of approximately 2.0 to 4.0.

3. Milled Ferro Silicon 15# is used extensively in the dense media separation process in both the metal recycling and mining sectors.

More About Ferro Silicon 

The physical properties of ferrosilicon: Different processes require different grades or types of ferrosilicon. And different ferrosilicon grades have different physical properties, which will determine the circuit performance of the product. In order to get the best ferrosilicon for your application, the main factors and characteristics to consider are medium density, viscosity, and stability, which are all interrelated. Please contact us and we will give you professional advice and service.

The process of ferrosilicon production: Iron ore (Fe2O3), quartz (SiO2), and carbon (C), in the form of coal, coke, and biocarbon, is added at the top of the furnace. Three electrodes in the furnace are heating the material. At approximately 2000˚C the carbon reacts with the oxygen in the quartz and we are left with liquid silicon. The iron oxide in the iron ore pellets reacts with the carbon through a similar reaction and forms pure iron. Melted iron and silicon mix and are then tapped in ladles. The metal is cooled and crushed into pieces of variable size, to meet the customer’s demand.
