disseminated deposit Deposit in which usually fine-grained ore minerals are scattered throughout the rock. Large, disseminated deposits form important sources of ore, e.g. porphyry copper deposits. Source for information on disseminated deposit: A Dictionary of Earth Sciences dictionary.
Ore is a type of rock that contains useful or valuable minerals, such as metals, gemstones, or energy resources. Learn how to define ore, then explore examples of its types and uses.

Mineral deposits are exceptional concentrations. The natural concentration processes that have given us ore deposits have often used water as the agent in various ways, mechanical and chemical; but some ores, and perhaps many, have been separated directly from the rock magma while an intrusive mass has been cooling and solidifying. Magma is the ...
An ore deposit is 'what is mined'. Precise definitions of the term are based on economics rather than geology, for instance: ore is rock that may be, is hoped to be, will be, is or has been mined; and from which something of value may be (or has been) extracted. (Taylor, 1989, Ore …
An ore deposit may also form as a result of several steps of processes that are identical but belong to different periods of geological history. Ore deposits are divided into deposits of ferrous, light, non-ferrous, noble, rare, and radioactive metals and deposits of trace elements.
ore deposits. The lateral extent of the Comstock ore body was mapped using self-potential methods in the 1880s. A very crude type of seismic survey measured the energy resulting from blasting operations in Ireland in the late 1800s. The idea that energy travels through a material with a certain velocity came from this survey. During

Indian Iron Ore Scenario : Low Grade Iron Ore Beneficiation Anand Kumar, Manager (mining), Omendra Singh, Design Engineer (Mining) MECON Limited, Ranchi - 834 002 Email : [email protected] Abstract Wide reserves of iron ore is found in India which is the basic raw material for iron and steel industry.
Ore is a deposit in Earth's crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron.. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire.Copper is also used in construction.
Accurate assaying is critical to the success of any iron ore exploration, resource definition and metallurgical testwork programme. X-ray fluorescence spectrometry (XRF) by fused bead is the method of choice for the analysis of oxide iron ores throughout the industry. The Iron Ore Technical Centre analytical laboratory has been
10. Schneiderhöhn Classification •Schneiderhöhn also considered only mineral deposits related to magmatic processes. •Four main classes are recognized depending on the nature of the ore-bearing fluids: intrusive and liquid-magmatic (magma), pneumatolytic (gases under high temperature-pressure conditions), hydrothermal (aqueous solutions ...
High-grade gold ore from the Harvard Mine, Jamestown, California, a wide quartz-gold vein in California's Mother Lode. Specimen is 3.2 cm (1.3 in) wide. Various theories of ore genesis explain how the various types of mineral deposits form within the Earth's crust. Ore-genesis theories vary depending on the mineral or commodity examined.
An "ore deposit" is a mineral deposit that has been tested and is known to be of sufficient size, grade, and accessibility to be producible to yield a profit. (In these days of controlled economies and integrated industries, the "profit" decision may be based on considerations that extend far beyond the mine itself, in some instances relating ...
The basic extraction of ore deposits follows these steps: Prospecting or exploration to find and then define the extent and value of ore where it is located ("ore body"). Conduct resource estimation to mathematically estimate the size and grade of the deposit. Conduct a pre-feasibility study to determine the theoretical economics of the ore ...
Sedimentary deposits are formed through the erosion, transportation, and redeposition of minerals that can survive the rigors of transportation. The most common is silica, which forms a number of materials, including silica sand, sand and gravel, and flint. The precursor is igneous quartz (e.g., in granite), and then the sedimentary deposit may undergo metamorphism and recementing to produce ...
Alluvial deposit: Clay or silt or gravel carried by rushing streams and deposited where the stream slows down. Anomaly: Zone determined by exploration methods to be different from its surroundings. Assay: Compositional analysis of an ore, metal, or alloy. Ball mill: Device used in grinding to reduce broken ore into powder.
ORE DEPOSIT TYPES Ore deposits can be classified on the basis of: - • Composition of the deposit (contained elements). • Form of the deposit (size, shape, orientation and ore mineral distribution). • Associated host rocks or geological structures (ore associations). • Interpreted genesis of the deposit (processes, controls).

An ore deposit is a well-defined mineral deposit that has been tested and found to be of sufficient size, grade, and accessibility to be extracted (i.e. mined) and processed at a profit at a specific time. Thus, the size and grade of an ore deposit changes as the economic conditions change. Ore refers to industrial minerals as well as metals.
Definition of ore deposit A body of ore or a mineral deposit that has been tested and is known to be of sufficient size, grade, and accessibility for minerals to be extracted to yield a profit. (In controlled economies and integrated industries, the 'profit' decision may be based on considerations that extend far beyond the mine itself, in some ...
and treatment of iron ore. Here, we describe in detail the metallurgical services SGS routinely provides to the iron ore mining market. At the broadest level, these include: • Metallurgical testing at the bench or pilot scale: • Geometallurgy highlighting ore variability. • Comminution testing, modeling and circuit specification.
Magmatic Ore Deposits Magmatic ore deposits are those which are formed during crystallization of a magma, deep underground. The host rock for the mineralization can range from ultramafic to felsic. The deposit can consist of massive ores in some cases, a nd disseminations of rare minerals in others.
An "ore deposit" is a mineral deposit which has high enough grades of metal that makes it economic to mine. Essentially this means that per tonne of rock containing the desired minerals, the costs of removing the minerals from the rock and separating the metal from the minerals are lower than the value of metal per tonne of rock.
You are making a deposit when you put money into your bank account. In that sentence, deposit is a noun, but you could express the same action using deposit as a verb. You deposit …
The cut-off grade is the arbitrarily defined lowest grade which will be mined from an ore ore deposit, and usually defines the boundary of the deposit. For example, if the average grade of a porphyry deposit is 0.5% Cu, the cut-off might be 0.2% Cu. any rock with a grade below 0.2% Cu would be waste.
