Ferro Silicon
Ferro Silicon is composed of iron, silicon and other minor elements.
Silicon Metal
Silicon Metal is obtained by carbothermic
reduction of silicon sources (quartz) in electric
submerged arc furnaces.
It is used as an alloying element for the production of carbon steel, special steels and cast iron products
that are present in our daily lives, such as cars, rebar, steel tubes, electric motors, metallic structures in
general, transformers and power generators.
MINASLIGAS
It is used in the chemical and technological
industry, in the production of industrial and
medicinal silicone, in addition to chips for
computers, smartphones and in the development
of products based on aluminum alloys.
At Minasligas, two grades of Ferro Silicon are produced:

Microsilica
Microsilica is an amorphous variety of silica,
which is formed in the production process of
Ferro Silicon and Silicon Metal. Part of the gas
rises to the top of the electric furnace, reacting
with oxygen in the atmosphere and generating
Microsilica, which is collected in the filters for
treating the gases effluent from the furnaces.
75% Ferro Silicon
STANDARD
Alloy with 75% silicon and approximately 24% iron.
75% Ferro Silicon
HIGH PURITY
Alloy with 75% silicon and approximately 24% iron.
However, in this product the elements Al, Ca, Ti and
C have a lower concentration compared to the
Standard product.
Microsilica is a useful raw material for the
concrete, ceramic and refractory industry,
improving the physical properties of these
products.
