stone. In bedded deposits, barites occur as the principal mineral or cementing agents in stratiform bodies in a layered sequence of rocks. They are the most commercially valuable and highly sought for because of its large tonnage deposits and high-grade barites (50-95% barites). Bed thickness ranges from few centimetres to 30 m and could

Some commercial drilling mud barites contain elevated (compared to marine sediments) concentrations of several metals. The metals, if bioavailable, may harm the local marine ecosystem. The bioavailable fraction of metals is the fraction that dissolves from the nearly insoluble, solid barite into seawater or sediment porewater.

In North America, magnesium chloride is produced primarily from Great Salt Lake brine. It is extracted in a similar process from the Dead Sea in the Jordan Valley. Magnesium chloride, as the mineral bischofite, is also extracted (by solution mining) out of ancient seabeds, for example, the Zechstein seabed in northwest Europe.

Pure barium is a pale yellow, somewhat shiny, somewhat malleable metal. Malleable means capable of being hammered into thin sheets. It has a melting point of about 700°C (1,300°F) and a boiling point of about 1,500°C (2,700°F). Its density is 3.6 grams per cubic centimeter. When heated, barium compounds give off a pale yellow-green flame.

Blanc-fixe is extracted from Barite. Barite is ground into a fine powder and dissolved in sulphuric acid containing free sulphur trioxide. The solution is then poured into water and then it gets a precipitate of barium sulphate. The precipitate is filtered and evaporated to get a crystalline substance, the barium sulphate or Blanc-fixe.
