metallic ore deposits

Metallic Deposits - CliffsNotes

Most metallic ore deposits are a result of plate tectonic activity. High heat flows and convection currents at divergent plate boundaries, such as midoceanic ridges, create submarine hot springs called black smokers that deposit solid masses of metallic minerals. These are important environments for the deposition of iron, copper, zinc, lead, gold, and silver. Metal‐laden solutions that are denser than

Ore Deposit - an overview ScienceDirect Topics

Ore deposits that are associated with mafic to ultramafic igneous rocks can generally be divided into those where the metals of interest are hosted in oxide minerals and those where the metals of interest are held as sulfides or are strongly associated with sulfides (e.g., PGE alloys, arsenides, bismuthinides). The oxide ore bodies include stratiform, podiform, and breccia-related chromite,

Metallic Ore Deposits Associated With Mafic to Ultramafic ...

01/01/2018  All metallic ore deposits represent anomalous concentrations of metals in the Earth’s crust. For some deposits, the mechanism through which the concentration occurs is clear, but in many, the processes involved remain elusive. In the case of Ni-rich deposits melting of olivine in the mantle should generate magmas with sufficient amounts of Ni that could be concentrated, from even low

20.1 Metal Deposits – Physical Geology

Tectonic Settings of Metal Deposits - Geology In

Ore Deposits and Plate Tectonics. P late tectonics, like crustal evolution, provides a basis for understanding the distribution and origin of mineral and energy deposits. The relationship of plate tectonics and mineral deposits is significant on three counts: Geological processes operating due to energy released at plate boundaries control the process of mineral deposition. Mineral deposits ...

20.1: Metal Deposits - Geosciences LibreTexts

11/08/2020  A metal deposit is a body of rock in which one or more metals have been concentrated to the point of being economically viable for recovery. Some background levels of important metals in average rocks are shown on Table 20.1, along with the typical grades necessary to make a viable deposit, and the corresponding concentration factors. Looking at copper, for example, we can see

Geology of Base-Metal Deposits

metals are not evenly or equally distributed within the deposit. In most mineral deposits, the ore elements are concentrated in zones in which one metallic element is enhanced relative to others in the deposit. Mining practices take advantage of this zoning by preferentially exploiting one part of a deposit relative to another if one base metal is

Hydrothermal ore deposits are a specific class of metallic deposits that form by a combination of (1) metal extraction from a source rock or magma by a hydrothermal fluid, (2) metal transport by a hydrothermal fluid from the source to a focused discharge where metals precipitate and accumulate, and (3) metal precipitation and accumulation (e.g., McCuaig and Hronsky, 2014).

Metal ore mining in Europe - Mineral Processing

The ore body in Kiruna is a massive block of high-grade magnetite ore, 4 km long, 80 m wide and extending over a depth of 2 km. Fig. 5 shows the proven existing reserves of iron ore at the 4 LKAB mines, as well as the iron grades of the ores in the reserves. The resources [3] are actually much larger, so that ore mining will be possible for several decades in Sweden if appropriate economic ...

Coltan - Wikipedia

Coltan (short for columbite–tantalites and known industrially as tantalite) is a dull black metallic ore from which the elements niobium and tantalum are extracted. The niobium-dominant mineral in coltan is columbite (after niobium's original American name columbium), and the tantalum-dominant mineral is the tantalite.. Tantalum from coltan is used to manufacture tantalum capacitors which ...

Volcanic Minerals - Oregon State University

Kuroko deposits are zoned from copper-rich near the center, to zinc-rich, to lead-rich at the outer edges of the deposit. The fluids that form Kuroko deposits have twice the salinity of average ocean water and temperatures of 250-300 C. This cross-section of a typical Kuroko deposit is from Sato (1974) and Franklin and others (1981). Modern-day VMS deposits of the Kuroko-style have been ...
