Limestone: Rock Uses, Formation, Composition, Pictures

Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3. It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.

The limestone dissolution rate for limestone-containing slurries used in wet flue gas desulfurization (WFGD) systems is enhanced by the addition of ammonium ions. The ammonium ions may be obtained by incorporating into the limestone-containing slurry gaseous or aqueous ammonia and/or a water-soluble ammonium salt, such as ammonium sulfate, ammonium chloride, or ammonium carbonate.
