Everything about Baryte totally explained
Baryte (
BaSO4) is a
mineral consisting of
barium sulfate. It is generally white or
colorless, and is the main source of
barium.
Barite is the unofficial American spelling. The mineral is also called
heavy spar or
tiff. The radiating form, sometimes referred to as Bologna Stone, attained some notoriety among
alchemists for the
phosphorescent specimens found in the
1600s near
Bologna, Italy by one Mr.
Vincenzo Cascariolo. Its
Mohs hardness is 3, the
refractive index is 1.63 and it has a
specific gravity of 4.3-5. Its
crystal structure is
orthorhombic.
Baryte commonly occurs in lead-zinc veins in
limestones, in hot spring deposits, and with
hematite ore. It is often associated with the minerals
anglesite and
celestine.
The name baryte is derived from the
Greek word
βαρύς (heavy). In
commerce, the mineral is sometimes referred to as "barytes." When the
International Mineralogical Association formed in 1959 the American spelling "barite" was chosen as the official over the older "baryte". This decision was reversed in 1978. The term "primary baryte" refers to the first marketable product, which includes crude baryte (run of mine) and the products of simple beneficiation methods, such as washing, jigging, heavy media separation, tabling, flotation, and magnetic separation. Most crude baryte requires some upgrading to minimum purity or density. Baryte that's used as an aggregate in a "heavy"
cement is crushed and screened to a uniform size. Most baryte is ground to a small, uniform size before it's used as a filler or extender, an addition to industrial products, or a weighting agent in
petroleum well
drilling mud.
Baryte is used in the manufacture of paints and paper. Although baryte contains a "heavy" metal (barium), it isn't considered to be a
toxic chemical by most governments because of its extreme
insolubility.
