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.
Where calcite limestone is uncommon or too costly, dolomite is sometimes used in its place as a flux for the smelting of iron and steel. Large quantities of processed dolomite are used in the production of float glass. In horticulture, dolomite and dolomitic limestone are added to soils and soilless potting mixes as a pH buffer and as a ...

Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth's sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either limestone or dolomite.

There are about 40 limestone and dolomite quarries in south-western Ontario but only a few of them have produced significant mineral specimens. All of them have some vugs of varying sizes with simple calcite or other crystals but only a few have fine, larger, well crystallized minerals such as fluorite, celestine, sphalerite, calcite, marcasite ...
Limestone where dolomite is present in more than a small amount are called dolomitic limestone. Dolomite is only rarely found in higher temperature metamorphic surroundings. Except in its pink, curved crystal habit dolomite is hard to distinguish from its second cousin, calcite.

Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolostone, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.
Marble is metamorphosed limestone and therefore consists mostly of calcite, although some marbles contain varying proportions of dolomite or calc-silicate minerals. Marble is a crystalline rock, usually white, but mineral impurities

Dolomite is a form of limestone, rich in approximately equal parts of magnesium carbonate and calcium carbonate. It is found widely throughout the world. Dolomitic limestone contains about five times as much magnesium and five eighths as much calcium as ordinary limestone.
The difference between the two is that limestone is composed mainly of the mineral calcite (made up of a combination of calcium, carbon, and oxygen) and dolomite is composed mainly of a mineral that is also called dolomite, which is like calcite with magnesium added.
Limestone is a calcium carbonate mineral whereas dolomite is made of calcium magnesium carbonate. Sand, clay and silt are commonly found in limestone as impurities but not quite common in dolomite. Calcite limestone is usually more expensive than dolomite.
Calcitic Lime vs. Dolomite Lime. On the surface, Calcitic lime and dolomite lime seem like very similar products. They are both made from pulverized limestone and both are effective at raising the pH in acidic soils. So what exactly is the difference between the two?
The mineral dolomite is the main component of the sedimentary rock that is also called dolomite. It is similar to the mineral calcite but contains magnesium as well as calcium. Just based on looks, the rock dolomite is often impossible to distinguish from limestone, which is composed mainly of calcite.
Commodity: Limestone, a sedimentary rock that is dominantly composed of the calcium-bearing carbonate minerals calcite and dolomite.. Calcite is chemically calcium carbonate (formula CaCO3). Dolomite is chemically calcium-magnesium carbonate (formula CaMg(CO3)2).
Formation of Dolomite from Limestone. Some limestones have been changed by the introduction of magnesium in groundwater. Magnesium in groundwater may convert some or all of the calcite in the limestone to dolomite. Also, some rocks formed near the shores of ancient seas in arid climates were mostly dolomite at the time they were deposited.
