Diablillos is one of the most recent high sulphidation precious metal discoveries in Argentina.

The Pavon low sulphidation system was discovered by Radius in 2003.

Low sulphidation deposits form in active geothermal systems with fluids dominated by ground waters.

Late-stage processes such as recrystallization, sulphidation, and oxidation also occurred.

The gold is hosted in low sulphidation epithermal veins and is open-pittable.

Gold mineralization at Blackwater could be considered as a bulk tonnage low sulphidation epithermal type of deposit.

High sulphidation hosted Cu-Au-Ag mineralisation is of interest.

Alteration includes sericitization, sulphidation, silicification and carbonatization.

Gold-silver mineralization occurs within quartz veins of the low sulphidation adularia-sericite epithermal style.

Cracow has produced in excess of 800,000 ounces of gold from high-grade, low sulphidation epithermal veins.

High sulphidation deposits occur within or adjacent to areas of active volcanism with significant direct input of magmatic fluids.

At around the same time, the discovery at depth of the Vera Nancy deposits was taking place within low sulphidation epithermal veins.

Potential to locate a larger porphyry style gold-copper system at depth or peripheral to the high sulphidation mineralisation, remains high.

Precious metal-rich epithermal mineralization with low sulphidation mineralogy and vein textures has been discovered at Centenario (200,000 oz.

"A significant body of mineralisation has now been defined with the characteristics of a low sulphidation, epithermal gold and silver system," Mr McNeil said.

Abacus Minerals Corporation's La Manchuria project best fits the model for a low sulphidation adularia - sericite gold - silver epithermal deposit.

These high grade zones are developed in wide zones of strong prophylitic alteration, tectonic milling and sulphidation and indicate multi-phase development of the gold mineralization.

"Low Sulphidation" means a class of epithermal gold deposits formed in neutral to slightly acid hydrothermal conditions and low sulphur activity, usually spatially away from igneous intrusions.

For instance, a single drill hole may intersect a high-grade zone in an otherwise low-grade (high sulphidation type epithermal) deposit, giving the appearance of a higher grade than actually exists.

The Trebol project located in northeastern Nicaragua is a low sulphidation epithermal hot springs district consisting of numerous strong gold anomalies spanning over 14 km of strike length.

Resorption of earlier formed platinum-group minerals into the immiscible sulphide melt and postmagmatic sulphidation destroyed most of the evidence of the early formed platinum-group minerals.

In contrast, epithermal mineralization hosted by the CA Tireo Formation is characteristic of low sulphidation epithermal mineralization with no demonstrable connection to intrusive activity.

Deposition of iron was not associated with silicification or sulfidation.

The sulfidation of tungsten is a multiple step process.

It is known that aluminum improves the sulfidation resistance of iron alloys.

Sulfidation is relevant to the formation of sulfide minerals.

Sulfidation is a process of installing sulfide ions in a material or molecule.

The process of liquid sulfidation has also been used in the manufacturing of diamond-like carbon films.

Sulfidic corrosion, also known as sulfidation, is the term used for the high temperature (above 450F) in contact with sulfur.

Specific research is conducted on oxidation, sulfidation, foil lamination, and several areas related to coal burning.

The inclusion of sulfidation in the process has been shown to reduce the friction coefficient of the dlc film.

In addition, Ni suffers from sulfidation attack at high levels of H2S or SO2.

They also have a 43-101 qualified resource at the El Porvenir high sulfidation play in Central Mexico.

A large scale application of sulfidation is the conversion of molybdenum oxides to the corresponding sulfides.

Corrosion in pipes is a problem at refineries because sulfur in crude oil reacts with steel, a process called sulfidation.

Other high-temperature corrosions include high-temperature oxidation, sulfidation and carbonization.

In addition, his gold research is also evaluating low sulfidation systems with work on the Pajingo epithermal deposit funded by Newmont.

Low gas-water ratios and fluid inclusion chemistry suggest that gold in the system was precipitated by a non-boiling mechanism, probably wall rock sulfidation.

One commonly encountered occurrence of sulfidation in manufacturing environments involves the sulfidic corrosion of metal piping.

Gold and silver mineralization is hosted in over 40 epithermal quartz veins and breccias of low to intermediate sulfidation.

Polysulfides are used as catalyst sulfidation agents and in the formulation of lubricant additives created for use in high-pressure environments or applications.

The compound is prepared by ortho-lithiation of benzenethiol using butyl lithium (BuLi) followed by sulfidation:

More selective syntheses entail (i) desulfurization, e.g. using triphenylphosphine and, complementarily, (ii) sulfidation using triphenylarsine sulfide.

Gold mineralization is primarily the result of sulfidation of the reactive iron by a moderately acidic ore fluid carrying gold as a bisulfide complex.

Alteration in the area is composed of silicification, pyritization, sericitization, alunite and pyrophyllite and is suggestive of a high sulfidation mineralizing system.

Our unique diffused aluminide coatings protect nickel and cobalt alloys from both high and low temperature hot corrosion/ sulfidation, oxidation, and particulate erosion.
