Our products are supplied in the form of raw magnesite and calcined magnesite.
Raw Magnesite
Raw magnesite products (Natural magnesium carbonate) are of cryptocrystalline and are characterized for its very low heavy metals and trace elements content. The MgO content of our products are in range of 70% to 92 % and the total production capacity is more than 3,000 tons per month. The production capacity for grades having MgO> 89% is about 1000 tons per month.
CCM (Caustic Calcined magnesia)
PPM produces and commercializes a wide variety of caustic calcined magnesia (CCM) products to meet different applications such as agricultural, industrial, chemical, construction, environmental, steel-refractories. Our products are acknowledged as top quality in their various fields of applications due to their low impurity levels, low heavy metals & trace elements, controlled physical characteristics (reactivity, surface area and etc.) and above all, being constant.

Dunite (silicate magnesium)
Dunite is a plutonic rock of ultramafic composition and is mainly characterized by coarse grained texture. Its chemical classification is basic rock, having mainly magnesium bearing olivine (forstrite) as the principal mineral, with minor contents of pyroxene. Dunite is a byproduct of Soltan Abad Bichend mine from the beneficiation process of magnesite and is used in the following main applications: - Abrasives - Ceramic Filler - refractory raw material - Land filler and pH control Serpentinization has been barely developed, therefore the olivine content can reach the level of >70% and L.O.I remained low in the range of 10 to 12%.
