A diverse group of deposits containing copper in association with nickel and platinum group elements PGE occurring as sulphide concentrations within mafic and ultramafic rocks. As a magma27 rises through the crust it cools and, if the sulphur content of the magma is sufficient, a separate liquid sulphide phase may develop droplets of sulphide
These deposits form when liquid magma rises through the earths crust and cools as it encounters cooler rocks. If the sulphur content of the magma is high enough or is extracted from the surrounding rocks through melting and if all the other geochemical essentials line up as the rocks cool further the sulphide liquid can crystallise and form ore deposits containing metals such as
Filtration is used to separate an insoluble solid from a liquid. It is useful for separating sand from a mixture of sand and water, or excess solid reactant from a solution .
Liquid immiscibility: sulfide ores containing copper, nickel, or platinum may form from this process. As a magma changes, parts of it may separate from the main body of magma. Two liquids that will not mix are called immiscible oil and water are an example. In magmas, sulfides may separate and sink below the silicate rich part of the intrusion or be injected into the rock surrounding it

Sulphide and silicate liquids are immiscible meaning they do not mix, so droplets of iron, copper, nickel and platinum sulphides that form at high temperatures and are denser than the surrounding silicate liquid magma sink to the base of the intrusion to form a cumulate layer, where they cool and crystallise.

Mantle derived magmas, however, have the potential to form a separate, immiscible magma or liquid of ironposition into which the small amounts of copper and nickel in the magma may be concentrated and eventually crystallize as discrete sulphide minerals. The iron rich magmas are capable of dissolving significant amounts of sulphur.
01/08/2020· The common coexistence of vapor rich and liquid rich fluid inclusions in porphyry copper deposits is reasonably interpreted as due to the separation of two immiscible phases phase separation but as noted above some controversy remains as to whether such phase separation was due to boiling or condensation.
The invention discloses a beneficiation method for copper and lead zinc separation by adopting liquid sulfur dioxide and solves the problems that in the existing method, the influence is generated on the separation operation concentration, and further, the effective separation of copper from lead zinc is not favorably realized. The beneficiation method adopts a sulfur dioxide addition
Evaporation is used to separate a soluble solid from a liquid. For example, copper sulfate is soluble in water its crystals dissolve in water to form copper sulfate solution. During evaporation,

Magmatic segregation is a general term referring to any process by which one or more mineralse locally concentrated segregated during the cooling and crystallization of a magma. Rocks formed as a result of magmatic segregation are called magmatic cumulates. While a magma may start

26/05/2020· Recently, experimental studies have suggested that intermediate to felsic magma may also be produced as hydrous melt through the separation of slab derived supercritical liquids
In contrast, experiments involving in situ high temperature centrifugation at 1000g g = 9ܮ m/s 2 did yield macroscopic unmixing and phase separation. Centrifugation for 34 h was insufficientplete phase segregation, and resulted in sub micron immiscible emulsions in quenched glasses.

Abstract:At the Bajo de la Alumbrera porphyry Cu Au deposit, NW Argentina, several key textural elements preserve evidence for volatile separation. Interconnected miarolitic cavities, while being studied extensively in granites, have now been recognized in intrusions related to porphyry Cu mineralization.
Immiscible melts A different kind of magmatic segregation involves liquid immiscibility. A cooling magma will sometimes precipitate droplets of a second magma that has an entirelyposition. Like oil and water, the two magmas will not mix i.e., they are immiscible.
Because the partition coefficients of nickel, copper and PGE, as well as iron, favor sulfide liquid over silicate liquid, these elements preferentially transfer into the sulfide droplets from the
consists in mixing the powdered ore with water, adding a small proportion of an oily liquid having a preferential affinity for metalliferous matter amounting to a fraction of one percent on the ore, agitating the mixture until the oil coated mineral matter forms into a froth, and separating the froth from the remainder by flotation.

Liquid immiscibility: sulfide ores containing copper, nickel, or platinum may form from this process. As a magma changes, parts of it may separate from the main body of magma. Two liquids that will not mix are called immiscible oil and water are an example.

Because the partition coefficients of nickel, copper, and PGE as well as iron favour sulphide liquid over silicate liquid, these elements preferentially transfer into the sulphide droplets from the surrounding magma. The sulphide droplets tend to sink toward the base of the magma because of their greater density, and form sulphide concentrations.

In volcanology, magma is melted rock that is under the ground. Magma is the molten rocks in Earth's mantle. Magma exists as pockets and plumes beneath the surface of the Earth. Magma is a molten and semi molten rock mixture found under the surface of the Earth. This mixture is usually made up of four parts: a hot liquid base, called the melt minerals crystallized by the melt solid rocks
