Sedimentary Mineral Deposits - Mineral Processing

2019-10-14  Mechanical Deposition of Sedimentary Mineral Deposits In some cases, the ore mineral, on account of its resistance to weathering and its hardness, survived the destruction of many of the rock minerals; and, during sedimentation, on account of its weight, it was sorted out from the fragments of quartz and other resistant minerals. Thus, the ore-mineral was deposited, without being chemically

Celestite (SrSO 4) is a mineral rarely found in sedimentary deposits other than evaporites, replaced evaporites, or insoluble residues of evaporites, whereas the related mineral barite (BaSO 4) is not so restricted ().Two main hypotheses have been proposed for the origin of large, sediment-hosted celestite deposits (Hanor, 2004): (1) syngenetic precipitation of celestite from

Of the two, celestite occurs much more frequently in sedimentary deposits of sufficient size to make development of mining facilities attractive. Strontianite would be the more useful of the two common minerals because strontium is used most often in the carbonate form, but few deposits have been discovered that are suitable for development.

Celestine (Celestite): The mineral celestine information

Celestine is isomorphous with Barite, and may partially replace it. One specimen may even be part Barite and part Celestite within a single crystal. Celestine is named from the Latin term caelestis, alluding to it typical celestial sky-blue color.

2019-10-16  Celestite crystallizes in cavity pockets of sedimentary rock such as limestone, dolomite, and sandstones. Celestite also may form from sea water precipitation, or as the result of evaporate deposits, or occasionally in hydrothermal deposits. Celestite’s hardness is rated at 3 to 3.5 on the Moh’s scale of mineral hardness.

Strontium Statistics and Information

2019-10-28  Strontium commonly occurs in nature, averaging 0.034% of all igneous rock; only two minerals, celestite (strontium sulfate) and strontianite (strontium carbonate), however, contain strontium in sufficient quantities to make its recovery practical. Of the two, celestite occurs much more frequently in sedimentary deposits of sufficient size to make development of mining
