3. Frasch process - Wikipedia

   en.wikipedia.org/wiki/Frasch_process

   Sulfur (m.p. 115 °C) melts and flows into the middle tube. Water pressure alone is unable to force the sulfur into the surface due to the molten sulfur's greater density, so hot air is introduced via the innermost tube to froth the sulfur, making it less dense, and pushing it to the surface. [1] The sulfur obtained can be very pure (99.7 - 99.8%).

4. Sulfur water - Wikipedia

   en.wikipedia.org/wiki/Sulfur_water

   Sulfur water is made out of dissolved minerals that contain sulfate. These include baryte (BaSO 4), epsomite (MgSO 4 7H 2 O) and gypsum (CaSO 4 2H 2 0). [1] It is reported that a notable change in taste to the water is found dependent upon the type of sulfate affecting the water.

5. Mineral spring - Wikipedia

   en.wikipedia.org/wiki/Mineral_spring

   Mineral springs are naturally occurring springs that produce hard water, water that contains dissolved minerals. Salts, sulfur compounds, and gases are among the substances that can be dissolved in the spring water during its passage underground. In this they are unlike sweet springs, which produce soft water with no noticeable dissolved gasses ...

6. Sulfuric acid - Wikipedia

   en.wikipedia.org/wiki/Sulfuric_acid

   When sulfur-containing fuels such as coal or oil are burned, sulfur dioxide is the main byproduct (besides the chief products carbon oxides and water). Sulfuric acid is formed naturally by the oxidation of sulfide minerals, such as pyrite: 2 FeS 2 (s) + 7 O 2 + 2 H 2 O → 2 Fe 2+ + 4 SO 2− 4 + 4 H +

7. Hydrogen sulfide - Wikipedia

   en.wikipedia.org/wiki/Hydrogen_sulfide

   Hydrogen sulfide can be present naturally in well water, often as a result of the action of sulfate-reducing bacteria. [ 47 ] [ better source needed ] Hydrogen sulfide is produced by the human body in small quantities through bacterial breakdown of proteins containing sulfur in the intestinal tract; it therefore contributes to the ...
