What is Atomized Ferro Silicon?
Atomized ferro silicon powder is spherical particles made by atomizing ferrosilicon powder with water atomization technology. Compared with ordinary ferrosilicon powder, the particle size of atomized ferro silicon powder is smaller.
Note: Atomized ferrosilicon powder cannot be matched with or replaced by common ferrosilicon. They are two different products. Check this page for ferrosilicon products.
The main types of atomized ferro silicon
The main types of atomized ferrosilicon on the market are FeSi15, FeSi45, FeSi75.
FeSi15 is mainly used in the mineral processing industry.
FeSi45, FeSi75 are mainly used in the production of welding rods.
Atomised Ferro Silicon for Dense Media Separation
The silicon content of ferrosilicon powder used as a heavy-medium separation should be controlled at 14%-16%. The mineral particles have different specific gravity, therefore, it is a good choice to use heavy media for beneficiation.
Due to its good corrosion resistance and good magnetism, FeSi15 is very suitable for heavy-medium separation. The ferro silicon can be recycled, so the low silicon ferrosilicon powder magnetic separation is the easiest and cheapest method. It is widely used in gold ore, diamond ore, aluminium ore, copper ore flotation.

Atomized ferrosilicon for welding rod
Atomized ferrosilicon is mainly used in the production of the welding rod. It is used as the coating of the welding rod, to improve the deoxidization of the welding rod.
During the welding process, oxygen, nitrogen, etc. in the air will affect the welding effect and cracks will occur in the welding joint. The electrode coating produces gas at high temperatures, which can reduce the reaction of welding metal and air.
