Thanks to a thorough selection process of mineral in origin, we can offer a high purity barite with excellent whiteness with our barite ultramicro  and barite R-2, which stand also for their high micronisation.

The barite P-5 and M-6 are characterized by a lower whiteness and a slightly higher particle size.

This range of natural barites is complemented with our precipitated barium sulphate Blanc Fixe Miber Extra, extraordinary in whiteness and micronization.

  • Blanc Fixe Miber® Extra (precipitated barium sulphate)
  • Barite Miber® Ultramicro
  • Barite Miber® R-2
  • Barite Miber® P-5
  • Barite Miber® M-6

For Kaolin we have boosted a unique high quality product, seeking the versatility of it. It's our Kaolin MIBER K-5. Due to its good whiteness and its particle size average of 5 microns it is suitable for many applications .

Alternatively, we can offer the kaolin MIBER K-7 when the whiteness is an important technical requirement.

  • Caolin Miber® K-5
  • Caolin Miber® K-7

In this family of products we differentiate between micronized quartz (Q series MIBER) and silica sand. Silica sand of differences sizes is obtained by sreening the raw material. No grinding is done.

The range of micronized quartz has the same whiteness, and we offer the following products from low to high particle size:

  • Quartz Miber® Q-10
  • Quartz Miber® Q-50
  • Quartz Miber® Q-80
  • Quartz Miber® Q-125

We have the following silica sand products:

  • Quartz Miber® 200/60
  • Quartz Miber® 300/100
  • Quartz Miber® 600/60
  • Quartz Miber® 900/400
  • Quartz Miber® 1600/160

MIBER CP-1 is a ultra-fine precipitated calcium carbonate, characterized by its high purity, small particle size and extraordinary whiteness.

MIBER A-2, A-3 and A-10 are natural calcium carbonate that share the same mineral source of high purity and whiteness. They differ from each other by their micronization level. They are suitable for various applications in paints and varnishes, paper, detergents, food additive, etc.

  • Precipitated calcium carbonate Miber® CP-1
  • Calcium carbonate Miber® A-2
  • Calcium carbonate Miber® A-3
  • Calcium carbonate Miber® A-10
