LIMESTONE (CALCIUM CARBONATE)
Limestone is a sedimentary rock containing a large amount of calcite and aragonite minerals (CaCO3). The two components have the same chemical formula, but the crystal structures are different. The nature, composition and distribution of limestone are directly related to the deposition conditions such as:
(1) Climate affecting the temperature and chemistry of water.
(2) The depth of water that affects the values of light and the mobility of the environment.
(3) The topography of the surface on which the limestone accumulates (coastal - continental shelf - sloping or collapsed sediments - basins)
Lake limestone deposited in a continental environment is mostly found on a local scale, is limited in comparison with marine limestone; limestone with carbonate rock (in some cases in a continental extension environment) is relatively rare.
Common limestone features include sand-sized granules, limestone sludge, and different amounts of welding materials. Purity (calcium carbonate content) is generally associated with the amount of mud, and high calcium limestone is often associated with high energy, therefore, contains a small fraction of the mud. In contrast, the Mikraite (micro-crystalline limestone) emanates from the accumulation of mud in the lagoon or deep water environment and tends to contain non-carbonate materials of the size of silt or mud making it less purity.
High-purity limestone has application as ground calcium carbonate (GCC) and precipitated calcium carbonate (PCC).
The principal consuming industries for white carbonate (GCC/PCC) fillers are paper, paint and polymers (plastics, rubber). With the trend to replace kaolin with GCC/PCC for paper filling and coating, the demand for high-purity limestone will increase.
