Many marine organisms use calcite minerals to construct their shells and skeletons. This is what makes this stone such a wonderful addition to Aria's collection of natural stones because it is an example of how stone can be a helping hand in the creation of life – as well as a beautiful art form! Calcite crystals found in a coral reef.

Calcite - Rocks And Minerals 4 U

The ease with which it dissolves and precipitates is the basis for many of calcite's uses in human society. Calcite's name comes from 'chalix' or 'chalx', which is the Greek word for lime ('calx' in Latin). For over 5,000 years, calcite has been used to manufacture lime (CaO, calcium oxide).

Jun 28, 2017· The mineral is an anhydrous carbonate mineral consisting of a double carbonate of calcium (Ca) and magnesium (Mg). It is chemically represented by CaMg(CO3)2 or CaCO3.MgCO3. It theoretically contains 54.35 % of CaCO3 and 45.65 % of MgCO3 or 30.41 % of CaO, 21.86 % of MgO, and 47.73 % of CO2 and has a molecular ratio of 1:1.

Calcite Facts

Calcite is a mineral that occurs in the natural geological processes of the Earth. Calcite is a form of calcium carbonate, a type of calcium salt oxide with three atoms of oxygen bonded to one atom of calcium. Calcite binds with other compounds to create limestone which is used in construction.

Formic Acid, HCOOH, is the simplest carboxylic acid and commonly found as the venom in ant and bee stings. Its chemistry and uses to the mineral collector are effectively the same as acetic acid and it can be used to dissolve calcite. Formic acid is a stronger acid than acetic acid and so it reacts more readily with calcite, dissolving it faster.

Calcite is truly one of the best collection type minerals. There are lots of interesting forms and varieties as well as colorful and beautiful specimens to collect. It is generally easy to identify using its rhobohedral cleavage, reaction to acid and double refraction and makes for a great classroom example of these properties.

Calcite Stone: Uses, Benefits and Meaning

The naturally-occurring mineral rock is a cartridge or media filter used to raise the pH of water in acidic water sources. Adding calcite to the water increases the pH level by offsetting its acidity. With the use of calcite filter media, you can prevent potential leaching of copper, lead, and other metals present in traditional plumbing systems.
