Limestone - an overview ScienceDirect Topics

Magnesium or dolomite limestone consists of magnesium carbonate (MgCO 3) and calcium carbonate (CaCO 3). It is commonly used as a liming material in areas where it is found. Magnesium carbonate has a better neutralising value than calcium carbonate of approximately 20%.

Lime Production: Industry Profile

2015-9-1  Limestone is converted into lime through heating in a kiln, a process known as calcination. When limestone is subjected to high temperatures, it undergoes a chemical decomposition resulting in the formation of lime (CaO) and the emission of carbon dioxide gas (CO 2). High-Calcium Lime CaCO 3 + heat CO 2 + CaO Dolomitic Lime CaCO 3 MgCO 3 + heat 2CO 2 + CaO MgO

Limestone - Formation, Composition, Types and Uses

Limestone’s chemical properties allow it to bond to sulfur dioxide and silica. For this reason, it is used in fuel gas desulfurization to remove toxic emissions from fossil-fuel power plants, remove impurities from iron, and control the viscosity of Limestone during Limestonemaking.

Limestone - Sedimentary rocks

Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%). It is the most common non-siliciclastic (sandstone and shale are common siliciclastic rocks) sedimentary rock.Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite). Carbonate rocks where the dominant carbonate is dolomite (calcium magnesium carbonate) are ...
