Carbonates dolomite

Shallow water carbonate (reefs carbonate muds) Reservoir quality governed by diagenetic processes and structural history (fracturing). Prolific production from karstified carbonates. High and early water production possible. Dual porosity systems in fractured carbonates. Dolomites may produce H S. 

The alkali metals of Group I are found chiefly as the chlorides (in the earth s crust and in sea water), and also as sulphates and carbonates. Lithium occurs as the aluminatesilicate minerals, spodimene and lepidolite. Of the Group II metals (beryllium to barium) beryllium, the rarest, occurs as the aluminatesilicate, beryl-magnesium is found as the carbonate and (with calcium) as the double carbonate dolomite-, calcium, strontium and barium all occur as carbonates, calcium carbonate being very plentiful as limestone. 

The carbonate minerals that comprise limestone ate calcite [13397-26-7] (calcium carbonate), which is easily the most abundant mineral type aragonite [14791-73-2] (calcium carbonate) dolomite [17069-72-6] (double carbonate of calcium and magnesium) andmagnesite [13717-31 -5] (magnesium carbonate). Individual limstone types ate further described by many common names (1). Some of this nomenclature is repetitious and overlapping. The following terms ate in common use in Europe and the United States. 

The main alteration minerals surrounding Kuroko ore body are K-mica, K-feldspar, kaolinite, albite, chlorite, quartz, gypsum, anhydrite, and carbonates (dolomite, calcite, magnesite-siderite solid solution), hematite, pyrite and magnetite. Epidote is rarely found in the altered basalt (Shikazono et al., 1995). It contains higher amounts of ferrous iron (Fe203 content) than that from midoceanic ridges (Shikazono, 1984).

Naturally occurring talc is mined and pulverized before being subjected to flotation processes to remove various impurities such as asbestos (tremolite) carbon dolomite iron oxide and various other magnesium and carbonate minerals. Following this process, the talc is finely powdered, treated with dilute hydrochloric acid, washed with water, and then dried. The processing variables of agglomerated talc strongly influence its physical characteristics. " ...

X-ray diffraction analysis of the products of the benefici-ation of Dow-Colony shale is shown in Table I. It is clear that the oleophilic extract (pellets) retains or concentrates the calcium and magnesium carbonates (dolomite, calcite, aragonite), particularly the dolomite. The hydrophilic gangue consists mainly of feldspar and quartz. Since silica, silicates and Ca/Ca-Mg carbonates, in a clean condition, are water wettable... 

On the whole, the mineralogical and chemical data indicate clearly the initial stages of the salting-up of the basin, viz. the dolomite-sulfate stage with a salinity of 7-20%. In other words, the terrigenous-chemical complex delineated here was deposited in a basin that became increasingly salty. The carbonates (dolomite and calcite) as well as the anhydrite still exhibit primary features, a conclusion drawn from the study of numerous thin sections. Complementary proof for this is furnished by the dolomite pebbles within the underlying sequence especially in the area of OMZ-i.

Of the group 2 metals, only Mg is manufactured on a large scale (see Box 12.1). The mixed metal carbonate dolomite is thermally decomposed to a mixture of MgO and CaO, and MgO is reduced by ferrosilicon in Ni vessels (equation 12.1) Mg is removed by distillation in vacuo. 

Calcite (CaCOj) and siderite (FeCOj) are commonly reported as constituents of the mineral matter in coals while the more complex carbonates dolomite (CaCOa MgC03) and ankerite (2CaC03 MgC03 FeC03) are also frequently reported.

The most common nonphosphalic accessory minerals associated with sedimentary phosphate rocks are quaife— clays, and two carbonates dolomite (CaMg(C03)2) and calcite (CaCOs). Carbonate-cemented phosphate rocks are particularly noteworthy because of their abundance. McClellan and Gremillion [14[ estimated that there are 3 tonnes of carbonate-cemented phosphate rock for every tonne of ore that could be handled by conventional milling and flotation processes (quartz- and clay-containing phosphate rocks). 

For conventional mineral fillers such as calcium carbonate, dolomite, mica, and wollastonite, the chemistry of each is constant across all grades of a given material and the grades are differentiated by their particle size, size distribution, particle shape, and presence (or otherwise) ofa surface treatment. In the case of POSS, every grade is chemically distinct and so properties such as density, polarity, refractive index, and so on, are different for each POSS [8] (Table 23.1). 

Among the other fillers where stearic acid could be used are aluminium and magnesium hydroxide, basic magnesium carbonates, dolomite (CaC03.MgC03) and magnesite (MgCOj). 

This mineral, which is also known as dolomitic limestone, is a major ingredient in several antacids, and food supplements. It is a mixture of approximately equal parts of calcium carbonate and magnesium carbonate. Dolomitic limestone contains about 5 times as much magnesium, and about 5/8 as much calcium as ordinary limestone. A typical analysis of dolomite follows calcium, 22.30% chlorine, 0.12% iron, 0.08% magnesium, 9.99% phosphorus, 0.04% and potassium, 0.36°/o. Dolomite is sometimes used as a calcium supplement for humans however, it should be tested and found free of lead and other impurities.
