    Only the sulfides are treated in the plant of concentration through flotation. The basic composition of sulfides is sulfur combined with different metals, in our case zinc, lead and silver. The products coming out of the plant are zinc sulfides (sphalerite) and lead sulfides (galena). Silver sulfide (argentite) is found in both products.

    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.
