	Welcome to our new Colemanite page!
		Colemanite, is a complex mineral, that is found in playa lakes and other evaporite deposits.
		Colemanite is a secondary mineral, meaning that it occurs after the original deposition of other minerals.
		Colemanite is found in geodes within the borax sediment; its exact means of formation are still not well understood.

	Colemanite near Stauffer, Ventura County, California
		Colemanite also occurs as irregular replacement bodies in limestone, along fracture planes and in fault zones as at the Russell mine.
		Gale (1913, 1914) suggested that the colemanite deposits were vein-like and could be the result of limestone replacement by borate solutions associated with formation of the basaltic flows.
		In summation, much colemanite may be available, particularly at depths within several hundred feet of the surface, but the cost of extraction and processing may be high.

	Method of preparing colemanite-containing glass batch - Patent 4074990
		In accordance with the present invention, boron-containing fiber glass batch pellets utilizing colemanite as a boron source are prepared by introducing the batch ingredients in appropriate proportions into a pelletizing zone, such as an inclined rotating disc pelletizer, as is shown in U.S. Pat.
		Colemanite has a chemical composition of Ca.sub.2 B.sub.6 O.sub.11.5 H.sub.2 O. Optionally, boric acid may be substituted for up to about 75 percent or more of the colemanite on an equivalent B.sub.2 O.sub.3 basis while adjusting for lost silica, calcia and alumina from the colemanite.
		The colemanite was not pretreated prior to its addition to the batch.

		Colemanite is a natural hydrated calcium borate and the chief domestic source of borax and boric acid.
		Colemanite can be used very satisfactorily in many raw lead glazes where the addition of CaO and B2O3 is desired without using a frit.
		Colemanite also can be used in combination with frits, but not so advantageously as in glazes of the raw lead type.

	Furnace Creek, Death Valley, California
		The colemanite occurs in masses of great purity, very much honey-combed and containing large numbers of crystals that reflect the light of the candle from myriads of faces as one makes his way into the tunnels.
		Colemanite, inyoite, meyerhofferite and ulexite all occur abundantly.
		This is especially true of the colemanite associated with the fine crystals of celestite.

	Method for producing sodium tetraborate pentahydrate - Patent 4857286
		A method as claimed in claim 1, characterised in that the colemanite is previously calcined at a temperature of between 250.degree.
		According to a further preferred embodiment, the discharge liquor from the crystallisation stage (c) is used in stage (a) to form the aqueous environment for the reaction between the mineral colemanite and sodium carbonate.
		According to the method of the present invention, the mineral colemanite after calcining and grinding is reacted with sodium carbonate in an aqueous environment to form an aqueous solution of sodium tetraborate and sodium hydroxide, with precipitation of solid calcium carbonate.

	Colemanite - Definition, explanation
		Colemanite (Ca O) is a borate mineral found in evaporite deposits.
		Colemanite is a secondary mineral that forms when borax is deposited, and then regularly covered with boron containing water.
		The boron remains after the water evaporates, and the boron and borax eventually form other minerals as for example Colemanite.

		Borate in both areas is in colemanite beds in the upper part of the Horse Spring Formation, a widespread 11-16 Ma nonmarine sedimentary unit in southern Nevada and northwestern Arizona.
		Colemanite was discovered in White Basin in 1920 and mined until 1924.
		The colemanite is fine-grained to coarsely crystalline and generally occurs as nodules with radial internal structure.

	Tick Canyon
		The beds carrying commercial colemanite were among the finer grained in the formation and consisted of thinly bedded red and brown sandstone, mudstone, and a purply silty shale, near the top of the Vasquez formation and between vesicular flows of basalt.
		Colemanite was mined through two vertical shafts, each 350 feet deep, from workings on the 100-200-300 foot levels and from numerous auxiliary openings.
		More plentiful colemanite cleavage fragments can be found on the dump of a smaller prospect to the east, marked by a mine tunnel, the bottom of which is full of water and forms the source of a small year round stream.

	Priceite - Furnace Creek California
		The minerals associated with the priceite are colemanite and gypsum.
		The colemanite forms small crystals coating the sides of the cavities or attached to loose masses of the priceite in the cavities.

	Ceramics Monthly - No More Gerstley Borate
		It was only when the supply of colemanite was cut off to ceramics industries that Gerstley borate was used as a substitute.
		One source in Argentina exports colemanite to the United States, but only in a 100-mesh size, which would be too coarse for a Gerstley borate substitute.
		A major importer of raw materials is currently testing the 200-mesh colemanite and may negotiate an exclusive agreement should it prove suitable for use in potters' glazes.

	Dissolution of Kestelek's Colemanite Containing Clay Minerals in Water Saturated with Sulfur Dioxide
		Colemanite is one of the most important underground riches of Turkey, having approximately 60% of the world boron deposits, and it has a large portion in the deposits.
		In this study, the dissolution of Kestelek colemanite has been investigated in SO -saturated water as an alternative method to the sulfuric acid process to remove the difficulties faced in filtration.
		It was determined that the dissolution rate of colemanite increased with decreasing particle size and solid-to-liquid ratio and increasing reaction temperature but was unaffected by the stirring speed.
