Classification and Nomenclature of Ore Reserves

In 1953, Dr N Fisher of the Bureau of Mineral Resources, acting on behalf of the Society of Economic Geologists, which is considering the sponsoring of a uniform system of nomenclature for ore reserves, enquired from The Australasian Institute of Mining and Metallurgy whether it had ever considered this subject and particularly whether it had Get price

Mineral Deposits: Meaning and Composition

Minerals in this category are Gold, Platinum, Tinstone, Magnetite, chromite, Ilmenite, Native copper, Gem stones, Zircon, Quicksilver etc. Apart from the metallic ores, rich deposits of salt and gypsum in sedimentary rocks are formed as a consequence of evaporation and precipitation of salts in ancient sea basins and lake basins.

Mineral dressing (= Orebeneficiation)

Mineral dressing (= Orebeneficiation) The first process most ores undergo after they leave the mine is mineral dressing (processing), also called ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate Get price

Iron ore: Mineral information, data and localities.

Ferruginous rock containing one or more minerals from which metallic iron may be profitably extracted. The chief ores of iron consist mainly of the oxides: hematite, Fe2O3 ; goethite, alpha -FeO(OH); magnetite, Fe3O4; and the carbonate, siderite FeCO3. Get price

Precious Metal Ores, Gold, Platinum, Silver and Copper

The ore minerals which form the sources of the valuable metals are almost without exception included in the following group of compounds: the sulfides and tellurides, the arsenides and antimonides, the oxides and oxidized compounds such as hydrous oxides, carbonates, sulphates, phosphates, and silicates, and one or two compounds of chlorine.

Cut

Mineral Classification. Cut-off grades are used to determine the point at which material becomes economically valuable. Therefore, they are necessary to define the amount of ore in a deposit. The classification of ore depends entirely on cut-off grade. Increasing the cut-off grade places a stricter requirement on what can be considered ore. Get price

Strunz Classification

Definition Prof Hugo Strunz introduced a chemical-structural classification of the entire domain of minerals (Mineralogische Tabellen, 1941), followed by A.S.Povarennykh with a modified classification (1966 in Russian, 1972 in English).The chemical-structural classification of H. Strunz has gone through a number of editions, and is currently in the process of being refined in the light of Get price

How Is Gold Extracted From Gold Ore?

Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of Get price

Types of Ore

Ore is rock that contains economic amounts of a particular element, e.g. gold ore, iron ore, molybdenum ore, or praseodimium ore. In contrast, rock that is not judged to contain economic quantities of an element is categorized as waste rock. The metals in ore can occur in many different minerals (compounds) in the rock. As an example, copper occurs in more than 50 minerals Get price
