Manufacturing process flow 1. Quarrying and Crushing The quarry (where the mining activity is performed) is located 0.7 km away from the plant and has the main raw materials such as Limestone and shale that is estimated to last for 100 years, the other raw materials (Iron ore, silica sand, gypsum and Pozzolana (pumice) ) are brought from nearby
The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km. The limestone is excavated from open cast mines after drilling and blasting and loaded onto dumpers which transport the materials
Thus, quarries are often associated with process plants the most important of which are ready-mixed-concrete plants, coating plants to produce asphalt and bituminous road-making materials, cement and lime burning kilns, concrete block and pipe works, brick works, pottery works and plaster/plasterboard factories.

Cement plants are usually built near the quarry of limestone so the quarried limestone can be transported to the cement plant directly by belt conveyor or other conveying systems. If the distance between the quarry and the cement plant is too long to use conveyors, the limestones will have to be transported by trucks, which means higher transportation fees and inconvenience.
