Dolomite is used as an ornamental stone, as a raw material for the manufacture of cement, and as a source of magnesium oxide. It is an important petroleum reservoir rock, and serves as the host rock for large strata-bound Mississippi Valley-Type (MVT) ore deposits of base metals (that is, readily oxidized metals) such as lead, zinc, and copper.

Lead-zinc in South Australia. ... Mineralisation is hosted by Hutchison Group serpentine marble, laminated graphitic, ankeritic, dolomitic marble and carbonate-facies BIF, and comprises massive pyrite–sphalerite–galena with minor chalcopyrite and pyrrhotite. The mineralising event may be related to intrusion of Mesoproterozoic rhyolitic dykes.
Zinc-lead skarns are composed of sp halerite and galena in calc-silicate rocks that may represent contact metasomatism by nearby granitoid intrusions or they may form hundreds of meters from intrusions inferred to be sources of metasomatizing fluids.
Hematitization of the dolomitic marble is locally extensive. Sphalerite, galena, pyrite, pyrrhotite and graphite occur in the dolomitic marble unit,with zinc and lead mineralization approaching significant proportions. The most commonly mineralized unit on the property is the silicated dolomitic marbles.

per cent lead is lost in the tailings it means a loss of 3,000 pounds of lead. This amount of lead at five cents a pound results in a loss of $150.00 per day. Considered in this light the prob lem assumes its true position. The determinations for zinc, though less accurate than those for lead, is of lesser importance because the amount of zinc
The orebodies lie within the upper 650m and are bounded by the Mount Isa fault on the west and by volcanic greenstones to the east. Comprising galena and sphalerite with pyrite and pyrrhotite, the lead-zinc-silver orebodies are concordant with carbonaceous dolomitic sediments, interfingering with the silica-dolomitic mass hosting copper.
Dolomite is the name of a sedimentary carbonate rock and a mineral, both composed of calcium magnesium carbonate CaMg(CO3)2 found in crystals. Dolomite rock (also dolostone) is composed predominantly of the dolomite mineral. Limestone that is partially replaced by dolomite is referred to as dolomitic limestone, or in old U.S. geologic literature as magnesian limestone.

Lead, zinc, and cobalt also substitute in the structure for magnesium. The mineral dolomite is closely related to huntite Mg 3 Ca(CO 3) 4. ... In horticulture, dolomite and dolomitic limestone are added to soils and soilless potting mixes as a pH buffer and as a magnesium source.
turbances resulting in an overfold. Subsequent to the overfolding, lead mineralization has taken place in dolomitic limestones. The lead-zinc minerals of Karempudi consist of Galena, Sphalerite, Jamesonite, Tetra-hedrite as primary minerals, and Anglesite as secondary mineral; there is association of chalcopyrite with Sphalerite. The textures ...

Dolomite can also serve as a host rock for lead, zinc, and copper deposits. In the chemical industry, dolomite is used as a source of magnesia (MgO). The steel industry uses dolomite as a sintering agent in processing iron ore and as a flux in the production of steel.

Dolomite serves as the host rock for many lead, zinc, and copper deposits. These deposits form when hot, acidic hydrothermal solutions move upward from depth through a fracture system that encounters a dolomitic rock unit.
Mississippi Valley-Type (MVT) Lead-Zinc Deposits are high grade lead and zinc sulfide deposits hosted in soft sedimentary host rocks such as limestone and dolostone. Their name reflects their historic occurrences along the Mississippi River in the United States.
Proterozoic pyritic shales elsewhere that are host to major lead-zinc deposits, such as Mt. Isa and McArthur River. However, in contrast to these deposits the pyritic shales of the Newland Formation contain only minute quantities of lead and zinc. Elevated concentrations of lead and zinc are only found in pore spaces of intercalated sandstone beds.
