Hard Rock Calcium, Calcium Carbornate Powder, Dolomite, Ground Magnesium limestone (GML), Raw LimeStone
 

GCC is delivered to a wide range of manufacturing industries; it is the most economical of all common filler minerals. Three primary attributes: particle size, color and chemical purity define the quality of the GCC, and define the suitability of use for any given application.

Our calcium carbonate distinctive advantages of high whiteness, regular particles and good dispersing ability, allow it to be widely used as functional filler in LATEX, RUBBER, PAINT, BUILDING MATERIAL, PAPER INDUSTRIES and etc.

  • We can produce the heavy calcium carbonate in different specification, as per our client request
  • Depending upon customer requirement, we can offer various grades and Particle size analysis report can be submitted along with supply
  • Kindly please email us to request the product specifications for 325 mesh , 200 mesh, 100 mesh or lower
