Treatment Methods of Lead & Zinc Ore
Lead and Zinc Ores Minerals of lead and zinc commonly are rather closely associated in nature zincfree lead ores and leadfree zinc ores are exceptional rather than common, although there are such. Lead and zinc ores usually contain some silver, but those of the Mississippi Valley region are silverfree. Indeed, leadzinc ores often are commercially valuable chiefly because of their silver
Introduction to Inorganic Chemistry/Ionic and Covalent
The morphology of twinned crystals of iron pyrite (FeS 2) is related to the underlying cubic symmetry of the unit cell.Like NaCl, the pyrite crystal structure can be thought of as a facecentered cubic array of anions (S 2 2) with ions (Fe 2+) occupying all the octahedral holes.

Sphalerite Wikipedia
Sphalerite ((Zn, Fe)S) is a mineral that is the chief ore of zinc.It consists largely of zinc sulfide in crystalline form but almost always contains variable iron.When iron content is high it is an opaque black variety, marmatite.It is usually found in association with galena, pyrite, and other sulfides along with calcite, dolomite, and fluorite.Miners have also been known to refer to

Acid Mine Drainage: Chemistry COTF
Acid Mine Drainage: Chemistry Acid mine drainage impacts stream and river ecosystems through acidity, ferric ion (Fe 3+) precipitation, oxygen depletion, and release of heavy metals associated with coal and metal mining, such as aluminum (Al 3+), zinc (Zn 2+), and manganese (Mn 2+).. When mineral deposits that contain sulfides are mined, they have the potential to produce acid mine drainage.

Common & Basic Formulas for Mineral Processing Calculations
On the other hand, the low sulphur assay of concentrate B shows this to be a marmatite, for 10% iron occurs in the form of FeS and only 2.5% iron as pyrite. The zinc mineral in this case contains 55.8% zinc, 10.7% iron, and 33.5% sulphur, and clearly is an intermediate marmatite.
Sphalerite The Zinc Blende
The chemical formula of sphalerite is ZnS zinc sulfide. This chemical formula represents sphalerite in its pure form, but it is much more commonly found with significant amount of other elements substituting zinc. Up to 26 % Fe, 17 % Cd, 15 % Hg, 21 % Mn and small amounts of Cu, In, Ga, Ge and As may replace the zinc.
Sphalerite: The primary ore of zinc and a collector's gem.
What is Sphalerite? Sphalerite is a zinc sulfide mineral with a chemical composition of (Zn,Fe)S. It is found in metamorphic, igneous, and sedimentary rocks in many parts of the world. Sphalerite is the most commonly encountered zinc mineral and the world's most important ore of zinc.. Dozens of countries have mines that produce sphalerite.
Sphalerite: Mineral information, data and localities.
Sphalerite Group. Sphalerite, also known as blende or zinc blende, is the major ore of zinc. When pure (with little or no iron) it forms clear crystals with colours ranging from pale yellow (known as Cleiophane) to orange and red shades (known as Ruby Blende), but as iron content increases it forms dark, opaque metallic crystals (known as Marmatite).
Zinc Wikipedia
Zinc oxide is widely used as a white pigment in paints and as a alyst in the manufacture of rubber to disperse heat. Zinc oxide is used to protect rubber polymers and plastics from ultraviolet radiation (UV). The semiconductor properties of zinc oxide make it useful in varistors and photocopying products.

What is pyrite's formula Answers
Copper pyrites is a common name for the mineral chalcopyrite, which has a formula CuFeS2. It can be considered to be made up of Cu+ Fe3+ S2 ions but there is covalent character.
Pyrite vs Sphalerite What's the difference? WikiDiff
is that pyrite is (mineralogy) the common mineral iron disulfide (fes 2), of a pale brassyellow color and brilliant metallic luster, crystallizing in the isometric system while sphalerite is (mineralogy) a yellow, brown or black, sometimes red, green white or colorless mineral with cubic crystals, of a chemical formula (zn]],fe)[[sulfurs.
2.6" Sphalerite, Pyrite and Quartz Association Peru For
Pyrite or iron pyrite is commonly referred to as Fool's Gold because it's metallic luster and pale brassyellow hue give it a superficial resemblance to gold. In the old mining days, Pyrite was sometimes mistaken for Gold. Pyrite is the most common of the sulfide minerals with the chemical formula FeS2. Pyrite crystals occur in many shapes and
Sphalerite: Amazing Zinc Gemstone Gem Coach
On a chemical level, sphalerite is the chief ore of zinc. It has an extremely simple chemical formula: (Zn,Fe)S. As you can see, zinc sulfide is the principal constituent, but iron is usually present as well. The degree of iron determines the appearance of the stone.
