Crystalline calcium in littorinid mucus trails | SpringerLink

Single-metal granules of Al, Ti, Mg and P were also found but only in the mucus trails of L. obtusata, perhaps reflecting its different collection site from the other two species. The mean size of the calcium granules showed significant interspecific variation (L. littorea, 1.32 µm diameter±0 08 µm, n = 143; L. saxatilis, 1.80 µm±0.12, n = 113; L. obtusata, 2.14 µm±0.09, n = 167).

Calcium - EniG. Periodic Table of the Elements

Calcium is obtained from minerals like chalk, limestone and marble. Pure metal is produced by replacing the calcium in lime (CaCO3) with aluminium in hot, low pressure retorts. Calcium is used by many forms of life to make shells and bones, as a pure metal it has little use, however two of its compounds, lime (CaO) and gypsum (CaSO4), are in great demand by a nuer of …

Calcium silie - Wikipedia

Calcium silie, also known as slag, is produced when molten iron is made from iron ore, silicon dioxide and calcium carbonate in a blast furnace. When this material is processed into a highly refined, re-purposed calcium silie aggregate, it is used in the remediation of acid mine drainage (AMD) on active and passive mine sites.
