Dolomite

Dolomite is a calcium magnesium carbonate mineral with the chemical formula CaMg(CO3)2, occurring naturally as both a mineral and the primary constituent of dolostone and dolomitic marble. This material is not mined directly in most cases but forms through the diagenetic alteration of limestone by magnesium-rich pore water, resulting in dense, sedimentary rock layers that can extend for hundreds of feet. The product supplied is derived from such geological formations, typically crushed and screened for industrial use rather than sold as crystalline specimens.

Dolomite used in construction and industrial applications generally contains between 38% and 42% calcium oxide and 20% to 24% magnesium oxide, with impurities such as silica, iron oxide, and alumina typically below 3%. The material is available in sizes ranging from 0-5mm for soil conditioning to 20-50mm for railroad ballast. As a natural sedimentary rock, it lacks the uniformity of synthetics but offers consistent chemical behavior when sourced from stable geological strata. It is not a refined product but a processed rock, with purity determined by the parent deposit.

Dolomite is primarily purchased by construction firms for use as aggregate in asphalt and concrete, by cement manufacturers as a flux in kilns, and by agricultural suppliers for soil pH correction. It is also used in metal processing as a sintering aid and in glass manufacturing to reduce melting temperature. Buyers typically order in bulk, with standard packaging in 25kg bags or bulk shipments via container. Trade terms are commonly FOB Dubai Port, with lead times of 7 to 14 days after order confirmation, subject to vessel availability.

Emirates National General Trading LLC is an import-focused trading entity based in Dubai, operating from Alsalamiyah Tower in Deira. The company does not operate a quarry or processing plant and sources dolomite from external suppliers, primarily in the Middle East and North Africa. Its role is logistical and commercial, facilitating bulk shipments to regional buyers. The supplier has no publicly listed certifications or manufacturing history, and its verification status reflects a harbor-tier trust rating with no recorded response activity.

There is no public information indicating ownership of mining operations, processing facilities, or laboratory testing capabilities. The company does not claim to produce or refine dolomite, nor does it provide technical data sheets or third-party test reports. Buyers should treat this as a sourcing intermediary, not a producer. All product specifications must be confirmed directly with the upstream supplier prior to purchase.
