ABSTRACT. Lime is a product derived from the thermal decomposition of limestone (mainly calcium carbonate, CaCO 3) into quicklime (CaO) and carbon dioxide (CO 2), also called calcination.Controlled reaction with water is used to manufacture hydrated lime (Ca(OH) 2) products.Lime is used in a wide variety of applications: metals industry, …

Carbonate minerals present in ancient limestones and dolomites occur in one of three textural forms: (1) discrete silt to sand to coarser carbonate grains, or allochems, such as oöids or skeletal fragments, (2) mud-size interstitial calcium carbonate matrix called microcrystalline calcite or micrite, and (3) interlocking, 0.02- to 0.1 ...

Introduction. Calcium carbonate is the most commonly used filler material in paper making (Naydowski et al., 2001).Ground calcium carbonate (GCC) is manufactured by grinding high quality limestone to very small sizes and is mostly used as a pigment, included as an externally applied coating in coated papers.

Calcium carbonate, which is also recognized as the chemical formula CaCO 3, makes up almost five percent of the earth's crust and is found all throughout the planet.CaCO 3 is a combination of CaO (calcium oxide) and CO 2 (carbon dioxide). Calcium carbonate's most common natural forms are chalk, limestone, and marble.

Limestone is an unusual rock in that it fizzes when dilute acid is placed on its surface. It is the presence of calcium carbonate that is responsible for this. The calcium carbonate content of limestone rocks has been used from the earliest civilisations, dating back to 14,000 BCE, to its extensive use in modern times.
