What is Limestone? 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.

Robert makes an excellent point here! Just try soaking a hard boiled egg in vinegar overnight. This will extract all of the calcium from the shell (1 shell is about 2000mg calcium). The vinegar causes the carbonate to be separated from the calcium. The carbonate evaporates as bubbles, and the calcium is left in the vinegar.
