S2-Yellow hues in lazurite - green tones are a combination of S-3 and S-2.
SO4-Ion radical also proposed as a source of blue coloration in lazurite (Samoilovich)

Geochemistry of Sulfur
Goldschmidt classification:Chalcophile
S6+ is one of the eight most abundant solutes in average river water.
S6+ solute can be a limiting nutrient in the growth of bacteria.
S6+ solute is a macronutrient on land.
S6+ is essential to nutrition of at least some vertebrates ('essential minerals').
S2- forms minerals with Cu+.
S2- forms minerals with Ag+.

Element association of Sulfur in the Mineral World
This table compares the known valid mineral species listed listed with Sulfur and the other elements listed based on the official IMA formula. Note that unlike other sections on this page this includes non-essential elements.

The first data column contains the total number of minerals listed with Sulfur and the element listed for that row.

The second data column lists this number as a percentage of all minerals listed with Sulfur.

The final data column compares this percentage against the percentage of all minerals that contain the element listed in each row.

Most widespread minerals containing Sulfur
This list of minerals containing Sulfur is built from the mindat.org locality database. This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Sulfur mineral species. It is more useful when comparing rare species rather than common species.

Important ores of Sulfur
Most sulphur is produced by desulfurization of petroleum products and cleaning of sulfur from smelting smokestack, but some sulfur is produced from roasting pyrite FeS2 and native sulphur is still mined in some parts of the world.
