University of Minnesota’s Mineral Pages: Dolomite

In industry, dolomite is an important source for magnesium and calcium metals, and is used as a flux for metallurgy. A flux is a material that melts easily and can be used to remove impurities from metal ores or to make the slag produced by metal ore smelting more fluid so it can be disposed of more easily.


The hardness in water is caused by certain salts. The main hardness causing ions are Calcium (Ca2+), Magnesium (Mg2+) and Bicarbonate (HCO3-). These ions are normally addressed as scale in the water causing (lime) scaling of pipes and equipment. Softening

calcium test kit for limestone in africa

Calcium is an alkaline-earth metal that is an important component of the cell walls of aquatic plants, and of the bones and shells of aquatic animals. Calcium ions find their way into water as it flows over rocks that contain calcium, such as limestone and gypsum.

University of Calcium Chloride by Manufacturers

Calcium chloride can serve as a source of calcium ions in solution, for instance for precipitation because many calcium compounds are insoluble: 3 CaCl2(aq) + 2 K3PO4(aq) → Ca3(PO4)2(s) + 6 KCl (aq) Molten CaCl2 can be electrolyzed to give calcium metal:

marble | Definition, Types, Uses, & Facts | Britannica

Marble, granular limestone or dolomite that has been recrystallized under the influence of heat, pressure, and aqueous solutions. Commercially, it includes all decorative calcium-rich rocks that can be polished, as well as certain serpentines.

What is the difference between hardness and alkalinity?

Hardness is the sum of the multivalent metal ions in solution, whereas alkalinity is a measure of the solution’s ability to neutralize acids (sum of hydroxide, carbonate, and bicarbonates). In natural water systems calcium carbonate is usually present and responsible for different characteristics of the water.

Water softening. How does it work? - Hytek

Water softening is the reduction of the concentration of calcium, magnesium, and other ions in hard water. These “hardness ions” can cause a variety of undesired effects including interfering with the action of soaps, the build up of limescale, which can foul pluing, and galvanic corrosion.
