Cerussite

 

a mineral; lead carbonate, PbCO3. Cerussite contains minute amounts of Ca, Zn, Sr, and Mg. It crystallizes in the orthorhombic system, forming columnar, dipyramidal, or tabular crystals. It often occurs in the form of stellate clusters of twinned or triplet crystals. It is usually found in the form of granular or sinter aggregates. A white, yellowish, or brownish gray mineral, it has a density of 6,400–6,600 kg/m3 and a hardness of 3.0–3.5 on Mohs’ scale. Cerussite is brittle. Under an electron beam it often gives off a greenish blue light.

Cerussite is a common secondary mineral in the zone of oxidation of lead deposits and occurs in association with anglesite, vanadinite, limonite, and other minerals. It is used mainly as an ore of lead and in the production of white mineral pigments. Deposits in the USSR have been found in Eastern Transbaikalia, the Altai, and Kazakhstan. There are also deposits of cerussite in the United States and Australia.
