Elemental sulfur is found in volcanic regions as a deposit formed by the emission of hydrogen sulphide, followed by aerial oxidation to the element. Underground deposits of sulfur associated with salt dome in limestone rock provide a substantial portion of the world’s supply of the element. These domes are located in the Louisiana swamplands of the United state and offshore in the Gulf of Mexico (Sulfur – Commercial Production | Britannica, 2025).
Titanium primarily found in igneous rocks as minerals like ilmenite and rutile. It’s commercially produced by reducing titanium chloride.
Chromium (Cr) is a hard, silvery transition metal with the atomic number 24, known for its remarkable corrosion resistance and ability to maintain a mirror-like surface even when exposed to oxygen. Chromium is mainly sourced from chromite ore. It’s produced by reducing chromite with carbon or chromium oxide with aluminum/silicon. It has significant deposits found in countries like South Africa, India, and Turkey(Chromium (Cr) | EBSCO Research Starters, n.d.).
