The U concentration in sedimentary phosphorite is generally between 50 and ppm, but can be as high as an interim review book, ppm, making it an increasingly important source of U for the nuclear industry.
The concentration of REEs in some sedimentary phosphorites is comparable to an interim review book world’s richest igneous and Chinese clay-type REE by: In south-eastern Australia, a variety of settings for sedimentary phosphate deposits has been recognized, with several producing a range of unusual, in some cases new species.

This chapter provides a review of world sedimentary phosphate deposits and occurrences. Sedimentary phosphate deposits are known on every continent except Antarctica and provide as much as 80% of the world's phosphate. They range in age from Early Proterozoic through Holocene, although some geologic ages were more phosphogenic than by: 2.

Breita,a, Alan E. Koeniga. Phosphorite, phosphate rock or rock phosphate is a non-detrital Sedimentary phosphate deposits rock that contains high amounts of phosphate phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5).Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O occurs through washing, screening.

Washington, U.S. Govt. Print. Off., is the sedimentary phosphate mineral. Two varieties of dolomite occur in the Hawthorn-hard, tough, cemented dolomite and soft claylike dolomite composed of uncemented tiny dolomite rhombs. Cited by: 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. 4 Sedimentary phosphate deposits Introduction Sedimentary an interim review book deposits or phosphorites contain few percents of calcium phosphate in form of grains of apatite, bone fragments or coprolites, and constitute important natural resources.
They are the major component of phosphorus fertilizers, and are widely used in chemical Size: KB. Sedimentary exhalative deposits (SedEx deposits) are ore deposits which are interpreted to have been formed by release of ore-bearing hydrothermal fluids into a water reservoir (usually the ocean), resulting in the precipitation of stratiform ore.
SedEx deposits are the most important source of lead, zinc and barite, a major contributor of silver, copper, gold, bismuth and tungsten.

By Leia Michele Toovey- Exclusive to Copper Investing News. SedEx, or sedimentary exhalative deposits, are ore deposits formed when hydrothermal fluids enter a water reservoir, such as an ocean. A large portion of the world's phosphate reserves are sedimentary type containing appreciable amounts of carbonate minerals.
These are the most difficult type of deposits to beneficiate. The depletion of other reserves easier to beneficiate, necessitates research to find methods of mineral processing for carbonate rich sedimentary phosphate Cited by: Iron formations, evaporites, and phosphorites are economically important chemical sedimentary rocks developed in basins which span a very large fraction of geologic time.
Since they are chemical precipitates, they must reflect the character of the body of water from which they were by: The origin of phosphate deposits About 15% of phosphate reserves are found in volcanic (extrusive) igneous rocks.
These reserves are found in Russia, Finland, South Africa and Brazil. Most phosphate reserves are from sedimentary rocks. The phosphate forms in the shallow oceans mainly due to bacterial activity, but only when several conditions File Size: KB.
Sedimentary Deposits mineral deposits formed during the accumulation of sediment on the bottom of rivers and other bodies of water. According to their place of formation they are divided into river, swamp, lake, sea, and ocean deposits.
Among ocean deposits a distinction is made between platform and geo-synclinal deposits. Depending on the type of. Sedimentary structures include all kinds of features formed at the time of deposition.
Sediments and sedimentary rocks are characterized by bedding, which occurs when layers of sediment, with different particle sizes are deposited on top of each other. These beds range from millimeters to centimeters thick and can even go to meters or multiple meters thick.
There are three main deposits of sedimentary phosphate deposits, along the red sea coast, in the Nile valley and in the Western Desert. The phosphate-bearing minerals in Egypt are known as the Duwi phosphate formation.
It consists of shale, lime stones, marls, sandstones, and phosphorites of about 20 m thick (Notholt et al., ).File Size: KB. SEDIMENTARY ROCKS. Prepared by T. Weiland for GEOL Sedimentary rocks - rocks formed by the accumulation and consolidation of sediments (surficial processes).
Sediments - material that is deposited by wind, water or ice; material that is precipitated from seawater; or deposits of organic origin. Major Components - (clastics, biogenic and chemical precipitates).

>Cheaper and with more reserves than oil, cleaner and more efficient burning. >Must be converted to highly explosive Liquified Natural Gas (LNG) form for effective transport overseas and contains greenhouse gases. The San Gregorio Formation in Baja California Sur, a phosphate-enriched sedimentary unit of late Oligocene to early Miocene age, has been analyzed in two areas (La Purisima and San Hilario) for its chemical composition (major oxides, Cu, Cd, Cr, Co, V, and rare-earth elements - REE) and isotopic composition (??18O and??13C).
A detrital and a marine component were determined from major. SEDIMENTARY MANGANES And IRON ORE DEPOSITS Most of the world's iron and manganese are derived from deposits of this type. These deposits are very large in size (thousands of millions of tons) and are usually mined by open-cut methods.
Sedimentary iron and manganese ores are deposited in both fresh and marine water, in bogs, swamps, marshes. Igneous deposit vs sedimentary deposit; Apatite and Ilmenite in Quebec: A World-Class Potential (presented at Québec Mines ) (French Language) The Lac à Paul apatite deposits are located in the Lac-Saint-Jean Anorthositic Suite (LSJAS), which belongs to.

Sedimentary rock - Sedimentary rock - Organic-rich sedimentary deposits: Coal, oil shale, and petroleum are not sedimentary rocks per se; they represent accumulations of undecayed organic tissue that can either make up the bulk of the material (e.g., coal), or be disseminated in the pores within mudrocks, sandstones, and carbonates (e.g., oil shale and petroleum).
