BARITE (Barium Sulfate) - Amethyst Galleries - Feldspar - Wikipedia
Class: Sulfates. Group: Barite. Uses: ore of barium. Specimens. Barite is a common mineral and makes very attractive specimens. It often is an accessory mineral to other minerals and can make a nice backdrop to brightly colored crystals. At times bladed or tabular crystals of Barite form a concentric pattern of increasingly larger crystals outward.Adopted on April 8, 1968. The barite rosette or "rose rock" has been the state rock of Oklahoma since House Bill 1277 was approved by the Oklahoma legislature on April 8, 1968, and was signed into law by Gov. Dewey F. Bartlett. Rose rocks are found in central Oklahoma, although barite deposits also occur in the Wichita and Ouachita mountains.

Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a post-transition metal, radioactive, and one of the pnictogens with chemical properties resembling its lighter group 15 siblings arsenic and antimony.Elemental bismuth may occur naturally, and its sulfide and oxide forms are important commercial ores. The free element is 86% as dense as lead.Barite (spelled also baryte) is a barium-bearing mineral (BaSO 4 ). It is mined both as an industrial mineral and as an ore of barium. This is somewhat unusual situation. Another well-known mineral mined as an ore and industrial mineral is zircon. Barite as the main barium-bearing phase in the crust is not uncommon mineral.

Sulfate minerals are delicate and occur near the Earth's surface in sedimentary rocks such as limestone, gypsum rock, and rock salt. Sulfates tend to live near oxygen and water. There is a whole community of bacteria that make their living by reducing sulfate to sulfide where oxygen is absent. Gypsum is by far the most common sulfate mineral. 01.These gems have low hardness (3-3.5), brittle tenacity, perfect cleavage, and heat sensitivity. Facet junctions on any cut gems also tend to be rounded. Due to barite's fragility, jewelry use isn't advisable. Nevertheless, faceted barites would likely appeal to collectors of unusual gemstones or aficionados of the art of gem cutting.

According to an EPA document, barium is found in low levels in most groundwater and surface water sources, typically less than 0.34 mg/L. We know now that barium occurs naturally and is an alkaline earth metal. When surface water flows past, or seeps through, rocks containing barium, some of the barium is dissolved in the water.Adopted on April 8, 1968.

The chemical formula for barite is BaSO4. It has a high specific gravity of 4.50 g/cm3. Its Mohs hardness is 3.0 to 3.5. Barite, which may be found in a variety of colors including yellow, brown, white, blue, gray, or even colorless, typically has a vitreous to pearly luster. Barite may be found in conjunction with both metallic and nonmetallic ...Steel abrasives are measured in Rockwell C hardness. They are produced in hardness ranging from 42 to 65. Steel grit provides an etch on a steel substrate, whereas steel shot provides a peened surface on a steel substrate. Shape The shape of an abrasive may be angular, blocky, semi-round or spherical.

Science & Origin of BariteBarite, or Baryte, is a barium sulfate mineral that crystallizes in the form of masses, tabular crystals, and even rarely, stalactites. This mineral was first recorded in 1800 by D.L.G. Karsten, and was named for the Greek word meaning "heavy", due to its high specific gravity.

Talc occurs as translucent, foliated or granular masses that vary in color from pale to dark green, with one perfect cleavage. Hardness is 1 (talc is a standard of hardness), streak is white, luster is pearly, and specific gravity is 2.7 to 2.8. Talc crystallizes in the monoclinic system.2000). Although hardness is caused by cations, it may also be discussed in terms of carbonate (temporary) and non-carbonate (permanent) hardness. 1.2 Sources The principal natural sources of hardness in water are dissolved polyvalent metallic ions from sedimentary rocks, seepage and runoff from soils. Calcium and magnesium,
