Classifications based on the morphology of the ore body could be quite useful, but have a tendency to mix apples with oranges (two ore bodies of similar shapes may be very different in type of ore, texture, origin, temperature of formation… etc.). Classifications based on the type of commodity are of little use in exploration; they are more useful for economists than geologists. Genetic classifications have always been the most fascinating, and genetic models have been used extensively in Native Elements. The native elements are those minerals formed wholely from elements which occur in an uncombined state. No ionic or covalent bonding may join atoms of one element to atoms of another within the lattice structure of such a mineral. Sulfides, Antimonides, Arsenides, Selenides, Tellurides, and Sulfosalts. Sulfides. Sulfide minerals are compounds of one or more metal or semimetal elements with the nonmetallic element sulfur (S). Oxides and Hydroxides. Simple and Multiple Oxides. Members of the oxide class are minerals in which an oxygen anion is combined with one or more metals. Halides. The halide class is composed of minerals in which an element of the halogen group such as fluorine (F), chlorine (Cl), bromine (Br), or iodine (I) provides the anion. corbettgeology.com › wp-content › uploadsof epithermal and porphyry ore deposits as an aid to mineral exploration. The classification of ore systems used here allows ore and gangue mineralogy, hydrothermal alteration, structure, breccias and the paragenetic sequence of events, to be employed as exploration tools to identify hidden ore systems. Zoned hydrothermal alteration provides

IMA Status: Valid Species (Pre-IMA) Prehistoric : Locality: Mexico and Norway have large deposits of silver. Known to ancient civilizations. Link to MinDat.org Location Data. Name Origin: Anglo-Saxon, of unknown origin. Name Pronunciation: Silver
Bauxite ore mostly exists in deeply weathered rocks. Volcanic rocks contain bauxite deposits in some regions. Iron metal extracted from iron ore. It never exists in pure form and has to be extracted from iron ore by eliminating the impurities. Gold is the oldest and most precious element to be known.
Epithermal gold-silver deposits range in size from tens of thousands to greater than 1 billion metric tons of ore and have gold contents of 0.1 to greater than 30 grams per metric ton and silver contents of less than 1 to several thousand grams per metric ton. Historically, these deposits have been an important source of gold and silver and are estimated to contain about 8 percent of global gold. The wide range of tonnage-grade characteristics makes epithermal gold-silver deposits an

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 (e.g., halides, oxides, and sulfides). Several reasons justify use of this criterion as the distinguishing factor at the highest level of mineral classification. First, the similarities in properties of minerals with identical anionic
If the silver price is $25 per troy ounce and the lead price is $1 per avoirdupois pound, the value of the lead in one ton of ore will be $1720, while the value of the silver in that same ton of ore will be $7292 (as shown in the diagram on the right).
Coarse silver mainly refers to the silver ore which contains 30%-99.9% of the silver, smelting primary silver products and recycling silver. The crude silver scope is relatively wide, resulting in diversity and complexity of the product species. In the crude silver, except for those relatively simple composition and known quality recycled silver products can be directly used, others are usually required by refined, concentrated integration of corresponding value metal elements. In addition Classification Of Silver Ore Classification Of Silver Ore » The silver occurs within the ores of these metals in one of two ways: 1) substituting for one of the metal ions within the ore mineral's atomic structure; or, 2) occurring as an inclusion of native silver or a silver mineral within the ore mineral. The value of this minor silver within the ore mineral can exceed the value of the primary metal within the ore.
Copper Group. Gold-Silver Series and Palladium-Silver Series. Silver is used in jewelry, tableware, coins, scientific equipment and in photographic processes. Silver tarnishes black with a surface layer of acanthite (silver sulphide), especially when placed in proximity to sulphurous compounds.
