Magnesite – Carbonate Magnesite for Industrial Application

Description

Magnesite (MgCO₃), carbonate magnesite,  is a natural mineral primarily composed of magnesium carbonate. It is a critical raw material for the steel, refractory, chemical, and agriculture sectors due to its high magnesium content and thermal resistance. Magnesite is used in the production of magnesia (MgO), refractory bricks, fertilizers, and magnesium compounds, making it an essential mineral in global trade.

At Call2Supply, we provide Iranian-origin magnesite in different grades and forms, including raw magnesite lumps, magnesite powder, and calcined magnesite, tailored to meet buyer requirements in international markets

• Applications of Magnesite

1. Steel Industry: Refractory linings in furnaces, converters, and ladles
2. Chemical Industry: Production of magnesium oxide, fertilizers, and flame retardants
3. Construction: Flooring, panels, and magnesia boards
4. Agriculture: Magnesium supplement for soil and animal feed
5. Environmental Uses: Neutralization of acidic wastewater, flue gas treatment

• Packaging & Delivery

*Bulk shipments in vessels (handymax, supramax, panamax)

* Jumbo bags (1–1.5 MT) or 25–50 kg PP bags for powders

* Flexible delivery terms: FOB Iran ports, CFR, CIF
