Calcite

Calcite is a carbonate mineral CaCO 3 (Fig. 1.13), and the most stable polymorph of calcium carbonate (calcite, aragonite, and vaterite).The color is milky white due to transparency with a yellow tint. The luster is vitreous with a white streak. The specific gravity of the mineral is 2.71 g/cm 3.The calcite in purest form contains 56.03% CaO and 43.97% CO 2.

Oolite is a sedimentary rock made up of ooids (ooliths) that are cemented together. Most oolites are limestones — ooids are made of calcium carbonate (minerals aragonite or calcite).Ooids are spheroidal grains with a nucleus and mineral cortex accreted around it which increases in sphericity with distance from the nucleus.

The first stage is the sedimentation process, from which chalk and limestone originate. Chalk is a poorly compacted sedimentary calcium carbonate rock whose diagenesis is incomplete. A completed sedimentation process results in the formation of limestone. If the sedimentation process takes place in water containing magnesium, dolomitization may occur.

Dolomite Lime – How Garden Lime Can Cause Problems

What Is Dolomite Lime? Dolomitic lime is calcium magnesium carbonate. It has something like 20% calcium and 10% magnesium, but that can vary quite a lot. When you buy dolomite garden lime, it has been ground into granules that can be coarse or very fine, or it could be turned into a prill, a pellet, not necessary but easier to apply.

The Dolomite Problem

The Dolomite Mountains, Italy's Alpi Dolomitiche, however, are a special case: the rock in them was originally simple calcium carbonate made from dead corals and seashells on the seafloor. Only later was it transformed into dolomite through the orderly addition of magnesium--and through the action, McKenzie suspects, of sulfate-reducing bacteria.

Water Handbook

The use of lime and soda ash permits hardness reduction down to 0.5 gr/gal, or about 8 ppm, as calcium carbonate. Magnesium is reduced to 2-5 ppm because of the lower solubility of magnesium hydroxide at the elevated temperatures. Silica Reduction. Hot process softening can also provide very good silica reduction.

BCCF About Calcium Carbonate

Dolomite. Dolomite is formed similarly to limestone except that the sedimentation process occurs in the presence of magnesium. Dolomitisation results in some of the calcium ions in the crystal lattice being replaced by magnesium ions and leads to the formation of dolomite CaMg(CO3)2 – calcium magnesium carbonate.
