Fluorspar Grades 

Our company deals with the following grades of fluorspar (Fluorite concentrate): 

    • GOST (all-Union State Standard) 29220-91: FK-75, FK-85, FK-92
    • GOST (all-Union State Standard) 29219-91: FF-95А and FF-95B
    • GOST (all-Union State Standard) 4421-73: FFS-95 and FFS-92
  Our company supplies fluorspar (Fluorite concentrate) of the following fractions: 0-300mm, 0-200mm, 0-150mm, 0-100mm, 0-80mm, 10-50mm, 6-60mm, etc. The grain-size composition of concentrates must meet the following requirements:
    • The maximum dimension of sorted lump fluorite concentrate of all grades shall not exceed 300mm, the gravity fluorite concentrate of all grades shall not exceed 200mm;

    • Mass fraction of particles smaller than 5mm in the concentrates of all grades must not exceed 10%;

    • In the gravity concentrates of all grades mass fraction of particles larger than 50mm should not exceed 10%;

    • In the gravity concentrate of FG-75, FG-65 grades mass fraction of particles smaller than 2mm should not exceed 5%.

    • In the concentrate of FGM-75 grade mass fraction of particles less than 5mm is not regulated.

    • The grain size of lump and gravity concentrate is determined in an optional way. • In the flotation concentrate mass fraction of particles of size 0.14mm should not exceed 10%.

    • The grain size of flotation concentrate is determined in an optional way. • In the lump concentrate of all grades the content of class minus 5mm should not exceed 10%.

    • In the gravity concentrate of all grades the content of class plus 50mm should not exceed 10%.
