Saudi Lime Industries’ quarries have the best Dolomite deposits in the region. Dolomite is sedimentary or metamorphic secondary origin rock [Ca, Mg(CO3)2], the theoretical composition of pure dolomite is 45.8% MgCO3(21.85 MgO) and 54.3%CaC03(30.4 CaO).
Usually the rock is associated with different impurities like clay, silica, iron and aluminum oxides. Hardness: 3.5 – 4 Mohs scale (Harder than limestone) Specific gravity: 2.85.
Saudi Lime Industries plants utilize state of the art screening facilities and can produce this nature sourced material meeting a wide range of ancillary products – in a variety of sizes, and a broad spectrum of industrial and agricultural requirements. Applications may include Glass and Rock Wool industries.
Dolomite comes Colorless, White, Gray, Black, and sometimes Reddish or Brown
Iron & Steel industry, Refractory, Fillers, Glass industry, Magnesium and Industrial Magnesia.
Rock wool industry, and Agricultural uses to control soil acidity and reduce the high level of potassium.
