An ore is any naturally-occurring source of a metal that you can economically extract the metal from. Aluminum, for example, is the most common metal in the Earth's crust, occurring in all sorts of minerals. However, it isn't economically worthwhile to extract it from most of these minerals.

Dolomite is a carbonate mineral, consisting of calcium magnesium carbonate. It was first described as the 'stinking stone' by Belsazar Hacquet, an Austrian naturalist. Later, Déodat Gratet de Dolomieu, a French naturalist and geologist, described it as a rock from the Dolomite Alps in Italy. Properties of Dolomite

To start the extraction process, a company mixes the seawater with its suspended salts, including magnesium hydroxide, with calcium oxide, also called lime, to make a slurry. The slurry is allowed to sit so that the solids settle to the bottom and the water rises to the top, and then the solids are removed, filtered, and washed to remove residual chlorides.
