Sulfides in a sentence

Scientists in many fields have explored the selective oxidation of sulfides to sulfoxides.

Drilling has confirmed that high-grade copper sulfides in the southern area are characterized by broad EM anomalies with a localized stronger EM signature.

The drill hole did encounter weak pyrite (iron sulfides) mineralization at 125m and minor clay layers, but not in an abundance to explain the EM response.

The drill holes have intersected 21.3m and 99.2m of visual copper sulfides (respectively) within what is interpreted to be the equivalent of the same mineralized stratigraphic horizon as the prior deep drilling.

Locally, mineralization occurs in narrow lenses of massive sulfides.

Note that there is a very low sulfides content, in the order of less than 0.2%, in the tailings from the treatment of Cheechoo samples.

They demonstrated that metal sulfides, including those of iron, copper, lead, and silver (some of which are common constituent minerals in hydrothermal vent environments), were converted to native metals by electroreduction.

Also, new evidence suggests that colonic H 2 S is largely present in bound forms, probably sulfides of iron and other metals.

Among more common minerals, oxides and sulfides tend to have a higher specific gravity as they include elements with higher atomic mass.

Bioleaching of non-sulfidic ores by layering of waste sulfides and elemental sulfur, colonized by Acidithiobacillus spp., has been accomplished, which provides a strategy for accelerated leaching of materials that do not contain sulfide minerals.

British Aluminium used the process of Paul Héroult about this time. citation The ores of base metals are often sulfides.

Carbon-sulfur compounds Important inorganic carbon sulfur compounds are the carbon sulfides carbon disulfide (CS 2 ) and carbonyl sulfide (OCS).

Chesterman and Lowe, p. 357 Sulfides are classified by the ratio of the metal or semimetal to the sulfur, such as M:S equal to 2:1, or 1:1.

Dyar and Gunter, pp. 644–648 Sulfides main Red cinnabar (HgS), a mercury ore, on dolomite The sulfide minerals are chemical compounds of one or more metals or semimetals with a sulfur; tellurium, arsenic, or selenium can substitute for the sulfur.

Here, many iron precipitates are found, mostly in the forms of iron sulfides and oxidized iron oxyhydroxide compounds.

In many cases these ligands are oxides or sulfides, but the metals are coordinated nonetheless, and the principles and guidelines discussed below apply.

It is also used in the Oddy test to detect reduced sulfur compounds and carbonyl sulfides.

Like the sulfides, sulfosalts are typically soft, heavy, and brittle minerals.

Many powdered sulfides, such as pyrite, have a sulfurous smell when powdered.

Other forms of tin ores are less abundant sulfides such as stannite that require a more involved smelting process.
