The Cement Manufacturing Process
How cement is made. Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are …

Limestone | Characteristics, Formation, Texture, Uses, & Facts
Most limestones have a granular texture. Their constituent grains range in size from 0.001 mm (0.00004 inch) to visible particles. In many cases, the grains are microscopic fragments of fossil animal shells. Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and …

Environmental Hazards of Limestone Mining | Sciencing
In humid climates, limestone dissolves quickly and is carried away by water. This creates caves which can become weak and collapse. Underground mining of limestone can cause a cascading environmental impact. Mining in the karst can lower the water table, which removes the support of rock that overlies water-filled caverns, which …
