The main ores of copper are sulfides and oxides. From their chemical formulas you can calculate the percentage of copper in each mineral. However this is not the same as the percentage of copper in the ore as that also contains unwanted silicates and other minerals, called gangue, that will have to .
types of ores and their chemical formula in chhattisgarh Science Chemical Reactions and Equations
Mineral Mineral Classification of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (, halides, oxides, and sulfides). Several reasons justify use of this criterion as the distinguishing factor at the highest level ...
Zinc processing Zinc processing Ores: Zinc ores are widely distributed throughout the world, although more than 40 percent of the world''s output originates in North America and Australia. The common zinccontaining minerals are the zinc sulfide known as zinc blende or sphalerite (ZnS), a ferrous form of zinc blende known as marmatite [(ZnFe)S], and a zinc carbonate known as calamine or ...

The Earth is the main source of minerals and ores. Most of the elements do not found in Free State because of their reactive tendencies. Potassium, sodium, calcium, magnesium, aluminium, zinc ...
Ores are those minerals from which metals are extracted commercially and economically. Like Bauxite (Al 2 O 3 2H 2 O) is the ore of Aluminium which contains 50% to 70% of Aluminium Oxide.
Mar 29, 2016· Chalcopyrite is a copper iron sulfide mineral, and its chemical formula is CuFeS 2. This mineral is naturally presented in a variety of ores; from huge masses to irregular veins and it is considered as the most important copper ore. Chalcopyrite oxidizes to several types of oxides, hydroxides, and sulfates when it is exposed to the air.
The chemical formula is Na 8 Al 6 Si 6 O 24 Cl 2. Tanzanite is a variety of Zoisite. It is valued as a gem stone and has the chemical formula Ca 2 Al 3 Si 3 O 12 (OH). Topaz is a silicate mineral that can be many different colors. The fact that it will take a high polish and is very hard makes it popular in jewelry. The chemical formula is Al 2 ...
Ores are very different from the finished metals that we see in buildings and bridges. They consist of the desired metal compound and the impurities and earthly substances called gangue. The extraction of metals and their isolation occurs over a few major steps.
This causes almost opposite characteristics in their physical properties. Graphite is very soft. It is used in the "lead" of pencils, which contain no lead at all, but are made of graphite and clay. Strangely enough, graphite has exactly the same chemical formula as diamond, the hardest substance known to mankind. They are both carbon.
The elements with a 2 in their formula are hydrogen, nitrogen and oxygen, plus the elements in group 7 (IUPAC group 17). Formulae of simple covalent compounds A compound contains two or more ...
Jul 03, 2019· Ternary acids commonly contain hydrogen, a nonmetal, and oxygen. The name of the most common form of the acid consists of the nonmetal root name with the ic ending. The acid containing one less oxygen atom than the most common form is designated by the ous ending. An acid containing one less oxygen atom than the ous acid has the prefix hypoand the ous ending.
Jul 03, 2019· Chemical or scientific names are used to give an accurate description of a substance''s composition. Even so, you rarely ask someone to pass the sodium chloride at the dinner table. It''s important to remember that common names are inaccurate and vary from one place and time to another.

Hematite is sometimes found in veinlike deposits which are not usually large enough to be important. Such orebodies have been found near Kitchener, and in the Matachewan area, Ontario. Deposits of considerable size have been found at the contacts of igneous intrusions, generally basic, with crystalline limestone, dolomite, and limey shale; the ore is usually of the specular variety, and ...
Nov 18, 2015· Metallic minerals contain metal elements in their chemical formula. The metal ores itself can be considered as a mineral. Some common metal minerals include Chalcopyrite, Iron, Copper, Gold, etc. Chalcopyrite is the most common Copper mineral and is an IronCopper Sulphide. Therefore, metallic minerals can be a homogenous ore of one kind of ...
Mar 20, 2019· Conversion of ore into metal a) The less reactive metals are extracted by reduction of their oxides by heat alone. For Ex: Copper and mercury 1)Ore of mercury is cinnabar Mercury oxide is reduced to mercury on heating. HgS(s) + 3 O 2 (g) —–> 2 HgO (s) + 2 SO 2 (g) 2 Hg(s) ——> 2 Hg(l) + O 2 (g) 2)Ore of copper is copper glance
Iron ores and their chemical formulas:Hematite(Fe2O3)Magnetite (Fe3O4)Goethite (FeO(OH))Limonite (FeO(OH).n(H20))Siderite (FeCO3)
The metals in ore can occur in many different minerals (compounds) in the rock. As an example, copper occurs in more than 50 minerals with varying percentages of copper in the chemical formulas of those minerals. The richest grade of copper ore is native copper, which is pure copper (). Many metallic ores occur as sulfide minerals.
