Some Industrial Mineral Deposit Models: Descriptive Deposit Mo

The ratio of gem quality to industrial diamonds in most economic deposits is about 1 to 4. The size, degree of brecciation, serpentinization, and diamond content of most pipes decreases with depth. Surface exposures generally consist of weathered kimberlite (yellow ground) that is enriched in diamond as a residual weathering product.

The proliferation of abandoned surface excavations and subsequent derelict of ore fields not only contribute to land degradation and landscape disruption but also result in loss of economic deposits, dearth of mining data and generation of unprotected spoils with known potential to contaminate ground and surface water sources.

Mineral Commodities of

Barite deposits in Newfoundland (Figures 1 and 2) include vein-type deposits (mostly on the Avalon Peninsula) and stratiform deposits (mostly in central Newfoundland); the latter are all associated with VMS- type base-metal mineralization, in which barite is a sec- ondary commodity. Minor vein-type occurrences are wide- ly scattered elsewhere.

Arizona Fluorspar

Almost all fluorspar deposits contain various amounts of impurities such as silica, calcite, barite, and metallic sulfides and therefore require beneficiation. In weathered exposures, fluorspar is a difficult mineral to find and identify. Because it is soft and friable, some forms tend to disintegrate rapidly when exposed-2-

Geology of Kentucky: Chapter 26, Vein Minerals - University of Kentucky

The common occurrence of barite, the abundance of fluorspar, and the entire absence of dolomite show that these deposits are related to the veins of the Cincinnati and Nashville uplifts. On the other hand, the argentiferous character of the galena, the abundance of fluorspar, and the occurrence of igneous intrusions in the region suggest a ...

Jul 2, 2021The term bentonite in drilling mud fluids was derived from the location of the first commercial deposit in the United States. In 1897, Knight reported that since 1888 William Taylor of Rock Creek, Wyoming, had been selling a "peculiar clay" found in the Fort Benton shale of Cretaceous age. Knight proposed the name "taylorite."
