Limestone, Application : Landscaping

Limestone is a sedimentary rock, composed mainly of skeletal fragments of marine organisms such as coral, forams and molluscs. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). About 10% of sedimentary rocks are limestones.

 

Limestone is the raw material for the manufacture of quicklime (calcium oxide), slaked lime (calcium hydroxide), cement and mortar. It is crushed for use as aggregate the solid base for many roads as well as in asphalt concrete. In some circumstances limestone is used for glass production.

 

There are two grades of limestone such as Steel grade and cement grade depends upon the silica content. We are producing high grade low silica limestone in our In-house quarry Orex Mining FZE, Fujairah. 

  

 

The company has been granted quarry area of approximately 1 Sq. Km encompassing 7 mountains with a max height of 250 m from mean sea level. The estimated reserve of high grade lime stone is estimated to be over 250 Million Ton. The lime stone excavated from the mines are crushed to the sizes of 0-5 MM, 5-10 MM, 10-20 MM, 0-40 MM & 40-80 MM for export of Qatar and Kuwait. Larger size of 40 mm and above with steel grade are exported to steel industries worldwide. 

 

 

 

1	Silica (SiO2)	0.35 %
