Zircon

It is sold in the form of :

• calibrated sands with a “G” grade for coarse up to AFS 62
• ground powders called “flours” (mainly 200 and 325mesh but also micronized)

The treatments carried out are in particular :

• grinding
• calcination at high temperature to purify the mineral
• classification/screening/mixing to adjust the granulometry

CMMP is able to make “tailor-made” in order to propose the product adapted to the very specific customer requests

ZIRCON is used in the following applications

• the production of refractory products (bricks, mortars…)
• the production of moulds in investment casting
• the production of brake pads
• the production of abrasives
• production of ceramics
• as a raw material for the extraction of Zirconium Zr or the production of Zirconia
• etc.

CMMP supplies CALCINED or UNCALCINED ZIRCON.

ZIRCON is particularly interesting for its physical and chemical stability, its hardness close to that of diamond (7.5 on Mohr’s scale), its toughness, its opacifying power and its very high refractoriness.

CMMP keeps ZIRCON in its natural form by subjecting it to mechanical (grinding) and thermal (calcinations) treatments.
