Carbonaceous sedimentary deposits transformed by metamorphism, in other cases reveal inorganic origin, as it is explained as the carbon (C) from hydrocarbons or perhaps combinations of carbonyl upwards. Manufacture of pencils, by virtue of his good conductor of electricity and heat, is used for electroplating coating molds to manufacture crucibles and molds that have to withstand very high temperatures, for use as a lubricant base. Also used to prevent oxidation. In recent years, graphite has earned the consideration of strategic mineral for building nuclear weapons, for use as moderator, in order to reduce the action of neutrons of uranium. The ruby and diamond rings white gold has been obtained larger Cullinan is called in South Africa in 1905, Approx. 650 gr. and he carved three large stones and 105 other smaller. Economic importance are the "Precious Metals": gold, silver and platinum. Native platinum (Pt) native ruby and diamond rings white gold (Au) ruby and diamond rings white gold Economy Exhaust Gas Catalysts Silver (Ag): Native Instruments does not usually appear doctors. These minerals are combinations of sulfur (S) (sulfur in Latin) with a metal Pyrite, iron sulfide, cinnabar, mercuric sulfide HgS FeS 2 Galena PbS, lead sulfide. Reservoir: Cantabria accompanying sphalerite in a strip running from Cazon to the Picos de Europa highlighting and Udías Reocín farms. Chalcopyrite, copper and iron sulfide cinnabar, mercuric sulfide HgS Galena PbS, lead sulfide Blenda: iron and zinc sulfide Cu Zn Hg Pb (Zn, Fe) S pellets Mercury Lead Copper Zinc Batteries Cables Alloys Brass Bronze Thermometer is highly toxic CuFeS 2. These minerals are salts that form the halogen elements Halite rock salt NaCl or sodium chloride potassium chloride KCl Silvina Fluorite Calcium fluoride CaF 2. Colorless, white or tinged yellow, red or blue. (When is blue or purple is a sign that was put inside the Earth to radioactivity). Great industrial importance because they are used to lower the melting point of metal ores, especially iron in blast furnaces. You can run a laptop, bipolar disorder, and even give the ceramic glaze brighter. The lithium could provide the energy that electric cars need not increase their weight and without the need for frequent stops to recharge the battery. Chile has exploited its rich salt deposits lithium to become the world's largest producer. The growing demand will require the exploitation of new deposits, including a deposit estimated at 5. 95 million tonnes are under a desert of Bolivia situated at high altitude. Lithium => Lithium ion is the positive electrode and graphite negative. The ions move through the plastic producing energy, the copper layers hold it together. NaCl Sodium chloride salt obtained in KCl Potassium chloride Silvina Fluorite CaF 2 Calcium fluoride preservative (salted) Fertilizer plants Dietary supplement potassium fluoride dental enamel. El Al is placed between every two hexagonal layers O. Each atom of Al is surrounded by six oxygen octahedral coordination. This structure voids, which theoretically should be busy it is termed defective. The chemical composition is a mixture of oxides of aluminum, iron and titanium, which gives it its characteristic color blue. Its chemical formula is Al2O3. These minerals contain the carbonate anion CO = 3 (calcium carbonate) Ca CO 3 Rhombohedral Calcite Aragonite hexagonal prism are an example of polymorphism (same composition but different crystal structure). Each C is surrounded by three O, CO 3 anion occupying the midpoints of the edges of the rhombohedral and the Ca center vertices and faces. CO 3 = ion is unstable in the presence of H + => react with HCl, producing effervescence (dolomite is produced only slightly charged when reduced to powder and hot HCl). In the limestone, which are composed of calcite, we obtain the lime (CaO, calcium oxide), with which traditional whitewashed houses of Andalusia and other Mediterranean peoples. Rhombic cell, sometimes comes with a hexagonal packing (twins) and dense Ca CO 3 anions occupying octahedral positions (= polyhedron with 8 triangular faces). Each cation has four valences If positive and two negative every oxygen, the oxygen after neutralizing the positive tetravalence Yes, there are four negative charges or electrons, which may join in with various cations ionic bond or other covalent bond tetrahedra. Single chain: pyroxenes, each tetrahedron is linked to its neighbors by two oxygen atoms and so on, leaving the atoms in a straight line sharing. Shared oxygens are situated in a flat or single-leaf and one free valence of free oxygen tetrahedra joined other sheets by means of various cations. The fundamental layer formed by tetrahedra of Si, O and sometimes is called siloxane sheet. The interlayer bonding may be brucite or gibbsite. Tetrahedra in three-dimensional framework. All the tetrahedra share four oxygens, leading to a complete neutrality. This condition is fulfilled only by quartz. The rest of the tectosilicates: four tetrahedra is one tetravalent Si is substituted by trivalent Al, allowing the existence of negative charges to produce union with cations such as Ca, Na and K mainly. Color banding and gives rise to a number of varieties, (carnelian, red, heliotrope, green with red spots or marbled, agate, with concentric bands, when they are called ruby and diamond rings white gold and black onyx), carnelian, chalcedony, red.
