HENGYANG will conduct feasibility studies based on the condition of
the raw ore, the metallurgical test report, the customer's mineral
reserves and investment scale, and the conditions for building the
plant, then propose a complete set of solutions for the plant which
includes engineering design, equipment manufacturing and supply,
logistics, installation, commissioning, training, trial production
and so on to ensure advanced technology, perfect processing,
efficient plant construction, reduced investment, environmental
protection and maximum benefits.
Uses of Fluorite
Fluorite has a wide variety of uses. The primary uses are in the
metallurgical, ceramics, and chemical industries; however, optical,
lapidary, and other uses are also important.
Fluorspar, the name used for fluorite when it is sold as the
concentrate after processing has the following three different
grades.
Acid Grade Fluorspar
Acid grade fluorspar is a high-purity material used to produce
hydrofluoric acid (HF). It contains over 97% CaF2. The hydrofluoric
acid is then used to manufacture a variety of products.
Ceramic Grade Fluorspar
Ceramic grade fluorspar contains between 85% and 96% CaF2. Much of
this material is used in the manufacture of specialty glass,
ceramics, and enamelware. Fluorspar is used to make glazes and
surface treatments that produce hard glossy surfaces, opalescent
surfaces, and a number of other appearances that make consumer
glass objects more attractive or more durable.
Metallurgical Grade Fluorspar
Metallurgical grade fluorspar contains between 60 and 85% CaF2.
Much of this material is used in the production of iron, steel, and
other metals. Fluorspar can serve as a flux that removes impurities
such as sulfur and phosphorous from molten metal and improves the
fluidity of slag.
Mineral processing
The common processing methods include manual sorting, gravity
separation and flotation. The good products can be obtained after
at least 6 stages of cleaners of flotation usually.
The concentrate after flotation is generally dewatered by
thickening and filtration, and then packaged and sold to the
smelting plant.
The tailings after flotation are pumped to the tailings impoundment
or the tailings are dewatered for dry stacking.
