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 …

Lime Production: Industry Profile
Also known as optical calcite; rare, extremely pure limestone, consisting of approximately 99.9 percent calcium carbonate. Contains between 5 percent and 20 percent magnesite, the intermediate between high-calcium and dolomitic limestone. Varies in purity and may be a high calcium or dolomitic limestone.
Lime Production
3.3.7 Shaft kiln (production of lime) Similar to cement clinker, lime is produced by the calcination of limestone, resulting in 0.79 tCO 2 /t Lime process-related emissions [ 77]. While rotary kilns can be used, the more energy efficient shaft furnaces dominate in Europe.
