Low-silicon iron powder is ferrosilicon powder containing a small amount of
silicon. Better low-silicon iron powder is made by smelting in electric furnace
and then atomizing with vacuum water in the process of high-precision
screening.

Low-silicon iron powder 15 # can be used as a heavy medium in mineral processing
industry, especially in waste aluminum separation, gold flotation, diamond
flotation, copper flotation and other fields. Ferrosilicon powder, a mineral
processing heavy medium, is a kind of low-silicon iron powder, but not all
low-silicon iron powders are suitable as mineral processing heavy medium. The
ideal mineral processing effect is ferrosilicon powder 15 #, which has a silicon
content of about 15% and a slightly higher iron content. It is suitable for
flotation and gravity mineral processing, and can be recycled after mineral
processing, and it is relatively simple to recycle!
