The Ghar Roubane barite lead–zinc deposit lies in the metallogenic province of Western Algeria. This mineral-ization site occurs in the form of barite veins, taking place within the Paleozoic schists and granites and fracture-filling in Liassic limestones. The Paleozoic basement shows barite veins of several hundred meters
contains several sediment-hosted lead-zinc resources, and a number of bedded barite sequences whose origins remain unknown. The major vent-proximal deposits of the Selwyn Basin, Tom and Jason, are thought to have formed in the Late Devonian based on the ages of their host rocks, the lower Earn group.

Barry County Lead and zinc mining in Barry County occurred primarily in the 1880s through 1890s, with some production in the 1910s, 1930s and 1940s (IMOP database). There was likely unrecorded production in the 1930s. The primary lead and zinc mining area was the Purdy mines area, located east of the town of Purdy. The mines are hosted …
The ore assemblage also varies remarkably, with lead:zinc:barium ratios ranging from approximately 3:1:0 at Ishiagu, to 2:1:0 at Enyigba, 1:0:2 at Wanikande and nearly barite at Gabu-Oshina.
The uses and properties of the mineral Barite. Barite Occurrence. Barite often occurs as concretions and void-filling crystals in sediments and sedimentary rocks.It is especially common as concretions and vein fillings in limestone and dolostone.Where these carbonate rock units have been heavily weathered, large accumulations of barite are sometimes …

Nigeria Lead–Zinc deposits hosted by the cretaceous rock was worked by Farrington (1952) and he discovered barite as one of the associated minerals. In 1987 the Nigeria Mining Corporation, now defunct, investigated five veins out of the eighteen veins in Azara field, Nasarawa State and reported a reserve of 730,000 tonnes of barite.
Most barite is mined from layers of sedimentary rock which formed when barite precipitated onto the bottom of the ocean. Some smaller mines utilize barite from veins, which formed when barium sulfate was precipitated from hot subterranean waters. In some cases, barite is a by-product of mining lead, zinc, silver, or other metal ores.
