Learning Geology Ore forming processes
Sep 17, 2014 Hydrothermal vein deposits are formed when these hydrothermal solutions enter a country rock along cracks and fractures. It precipitates in the parent rock in a vein like structure. The hydrothermal solution in vein deposits can also soak through the country rock which for disseminated ore deposits.This is less concentrated but as formed with the vein together they form economical deposit.

Hydrothermal mineral deposit geology Britannica
Hydrothermal mineral deposit, any concentration of metallic minerals formed by the precipitation of solids from hot mineral-laden water hydrothermal solution.The solutions are thought to arise in most cases from the action of deeply circulating water heated by magma. Other sources of heating that may be involved include energy released by radioactive decay or by faulting of the Earths crust.

How Does Iron Ore Form Nearly all of Earths major iron ore deposits are in rocks that formed over 1.8 billion years ago. At that time Earths oceans contained abundant dissolved iron and almost no dissolved oxygen. The iron ore deposits began forming when the first organisms capable of photosynthesis began releasing oxygen into the waters.

Ore deposits formed by oxidation and supergene enrichment
Ore Deposits Formed by Oxidation and Supergene Enrichment When ore deposits are exposed to the oxidation zone they are weathered and altered with the country rocks. The surface waters oxidize many ore minerals and yield solvents that dissolve other minerals. An orebody thus becomes oxidized and generally leached of many of its valuable materials down to the groundwater table, or to ...

Ore Deposits Formed by Metamorphism
Ore Deposits Formed by Metamorphism Metamorphic processes profoundly alter pre-existing mineral deposits and form new ones. The chief agencies involved are heat, pressure, time, and various solutions. The materials acted upon are either earlier formed mineral deposits or rocks. Valuable nonmetallic mineral deposits are formed from rocks chiefly by the crystallization and the ...

Different Types of Iron Ore
Oct 05, 2016 Limonite is sometimes formed in large quantities by the weathering of the sulphides of iron such gossan has occasionally been used as an iron ore. At Bannockburn, in the Madoc area, a pyrite deposit was discovered below the limonite, which was being mined as an iron ore this gossan capping of the pyrite was from eight to fifteen feet deep.
How Is Bauxite Formed
Mar 27, 2020 The type of bauxite ore produced is heavily dependant on the region and conditions the ore is created in. Both types depend on heavy weatherization and above average drainage capacity to form.

Ores and Minerals Introduction Extraction
First ores are crushed and grinded and then gauge or matrix is removed from the powdered ore. This is called concentration of ores. Ores of highly, moderately, and low reactive metals are 1 st concentrated. This step is common for ores of all types of metals. It is carried out by various methods depending upon the nature of the ore.
How Ore Deposits Are Formed Geology In
The ore deposit has a typical, well-defined shape that resembles the cap of a mushroom. Its stem is the volcanic vent, which has solidified into porphyry and then cracked to form numerous veins through which the fluid pushed its way upwards.

Ore deposits formed in sedimentary environments Chapter
Ore deposits form in sedimentary environments as a result of one of two generalised geological processes either as a result of mineral precipitation from solution in surface waters, most commonly from sea water or lake waters or as a result of physical accumulation of ore minerals during processes of sediment entrainment, transport and deposition.
Aluminum processing Ores Britannica
Aluminum processing - Aluminum processing - Ores Aluminum is the third most abundant element on Earths surface. Only oxygen and silicon are more common. Earths crust to a depth of 16 km 10 miles contains 8 percent aluminum. Aluminum has a strong tendency to combine with other common elements and so rarely occurs in nature in the metallic form.
Processes of Ore Formation
Rocks formed in this manner are termed cumulates and are often characterized by rhythmic layering. In ore deposits the alternating layers are often magnetite andor chromite between layers of silicate. Ex. Bushveld igneous complex. Immiscible liquid - Typical example is oil and water. In ore deposits we deal with silicate and sulfide magmas.

The few books in existence on ore petrology give too little consideration to weathering processes, to formation of ores and gossans produced by weathering, or to ores in unconsolidated sediments such as placers. This is an oversight that requires remedy since many valuable ore deposits are formed by a variety of exogenetic processes.
Mineral Deposits National Geographic Society
Jun 28, 2019 A mineral is a naturally occurring crystalline solid that cannot be physically broken down into smaller components.. Deposits of minerals form when a medium that contains and transports mineral-making ore releases and deposits the ore. Magma is one such medium that transports ores. When magma or lava cools, the magma and ore carried within it crystallize to form tiny minerals in
