The Sulfide Class minerals comprise an economically important class of minerals. Most major ores of important metals such as copper, lead and silver are sulfides. Strong generalities exist in this class. The majority of sulfides are metallic, opaque, generally sectile, soft to average in hardness and they have high densities, black or darkcolored streaks, and an igneous origin.
Cobalt naturally occurs in nickelbearing laterites and nickelcopper sulfide deposits and, thus, is most often extracted as a byproduct of nickel and copper. According to the Cobalt Development Institute, about 48% of cobalt production originates from nickel ores, 37% from copper ores and 15% from primary cobalt production.
Cobalt – Occurrence, Production, Use and Price The other half of the global output of cobalt is from copper–cobalt mines, loed mainly in Zambia and the Democratic Republic of Congo.
