Sulfide minerals are important sources of many metals and are mined where they occur in economically viable concentrations. Most of these minerals may be precipitated from hydrothermal solutions, and complex sulfide and sulfosalt assemblages are found in hydrothermal vein-type or replacement deposits. In addition, major concentrations of Fe filexlib. Sulfide minerals in hydrothermal deposits are the primary source of the base metals Cu, Zn, Pb and a large number of other, lower-concentration metals that include Ag, Tl. These metals may form their own sulfides or occur as minor or trace elements in other sulfides and sulfosalts. "Treatment of sulfide mineral flotation concentrates can also be carried out using hydrometallurgy, in which process the metal sulfide is dissolved (leached) into an aqueous solution ." 29 Using this process rather than smelting eliminates the sulfur dioxide concerns. 30
Elements
Sulfide minerals in hydrothermal deposits are the primary economic source of metals used by society, which occur as major, minor and trace elements. Sulfides also play a key role during magmatic crystallization in concentrating metals that subsequently may (or may not) be supplied to hydrothermal fluids.

Sulfide minerals are compounds in which sulfur is combined as an anion with a metal (or semi-metal) cation or cations. The definition is commonly widened to include minerals in which the anion is As or Sb, sometimes together with S, and to include Se and Te minerals. The sulfosalts are a special group of the sulfide minerals that have a general
The purpose of this study is to investigate the toxicity of common metal-sulfide minerals (copper-sulfides, copper-iron-sulfides, arsenic-iron-sulfide, lead-sulfide, and zinc-sulfides) that are mined or present in ore deposits as gangue minerals. Each of the materials evaluated is briefly described below. 1.1. Selected Metal-sulfides
