Named after the Latin word calx for lime (calcium oxide, not the fruit!), calcium was used in ancient Rome as early as the 1st century. It wasn''t until 1808, though, that it was isolated in a nearly pure metallic form by Sir Humphrey Davy (1778-1829, right ), a brilliant scientist who also discovered/purified magnesium, strontium and barium.

mineral processing role of magnesium in plants
Limestone is mainly composed of calcium carbonate (CaCO3), MO''s Hardness 3 degrees. The limestone particles or powders can be used in building materials, road construction, metallurgy, chemical and other industries after crushing or grinding.
Dolostone is quite similar to limestone, but is composed mostly of the mineral dolomite (CaMg(CO3)2). Dolostone forms when magnesium in pore water is substituted for some of the calcium in the original limestone, or by direct precipitation.

Secondary Plant Nutrients: Calcium, Magnesium, and …
Calcium, magnesium, and sulfur are essential plant nutrients. They are called “secondary” nutrients because plants require them in smaller quantities than nitrogen, phosphorus, and potassium. On the other hand, plants require these nutrients in larger quantities
Hard Water Hardness Calcium Magnesium Water …
Calcium and magnesium dissolved in water are the two most common minerals that make water "hard." The degree of hardness becomes greater as the calcium and magnesium content increases and is related to the concentration of multivalent ions dissolved in the water.

3 Minerals – An Introduction to Geology
Carbonate minerals are salts built around the carbonate ion (CO3-2) where calcium and/or magnesium replace the hydrogen in carbonic acid (H 2 CO 3). Calcite and a closely related polymorph aragonite are secreted by organisms to form shells and physical structures like corals.
