OVERVIEW OF DOLOMITE
Dolomite is an important calcium-magnesium resource, primarily composed of magnesite and
calcite, with minor amounts of clay minerals and chert, and occasionally containing gypsum,
celestite, barite, pyrite, organic matter, etc.
Abundant in reserves and distributed across all provinces, dolomite boasts proven deposits
sufficient to meet the demands of economic development. Characterized by high contents of
MgO and CaO, together with higher purity and fewer impurities, dolomite serves as a
high-quality raw material for industries such as metallurgy, chemical engineering, building
materials, rubber, and refractories.
As a non-metallic mineral resource with considerable economic value and potential for
diversified development and utilization, the fine processing, efficient and rational
utilization of dolomite are of vital importance.
APPLICATION OF DOLOMITE
Dolomite can serve as a refractory inner lining for converters in steelmaking, a slag-forming agent,
a raw material for cement production, a flux in glass manufacturing, and a key material for
ceramics, fertilizers, construction and decorative stones, coatings, pesticides, pharmaceuticals,
and other applications.
It is also widely applicable in sectors such as building materials, ceramics, glass and
refractories, chemicals, as well as agriculture, environmental protection, and energy conservation.
After being processed into powder, dolomite boasts a wide range of applications. It can be used to
produce new-type refractory materials and smelt magnesium metal, boosting industrial production; it
can also improve soil pH levels to serve agriculture and forestry, and is applicable to scenarios
such as coatings, putty powder, papermaking and PE manufacturing, thus emerging as a high-quality
raw material across multiple fields.
New-Type Refractory
Materials
Fine-ground dolomite can be used in new-type refractory materials.
Magnesium Industry
Pulverized dolomite is applicable to magnesium metal smelting.
Building Materials
Dolomite can be used to manufacture magnesia cement and coatings.
Agriculture and Forestry
Dolomite powder is effective in regulating soil pH levels.
DEEP GRINDING PROCESSING OF DOLOMITE POWDER
