... Bromine and iodine are produced by chemical reduction of NaBr and NaI with Cl 2; the ocean is also their major source of these elements. Fluorine is derived from fluoride containing minerals such as fluorospar (CaF2) and fluoroapatite (Ca5(PO4)3F). Sulfur is obtained from sulfur deposit and ph ...
