sphalerite ((zn, fe)s) is a mineral that is the chief ore of zinc.it consists largely of zinc sulfide in crystalline form but almost always contains variable iron.when iron content is high it is an opaque black variety, marmatite.it is usually found in association with galena, pyrite, and other sulfides along with calcite, dolomite, and fluorite.miners have also been known to refer to
with the gradual depletion of zinc sulfide ores, exploration of zinc oxide ores is becoming more and more important. hemimorphite is a major zinc oxide ore, attracting much attention in the field
precious metals can be found in ore deposits along with sulfur, and are known as sulfides. cadmium, cobalt, copper, lead, molybdenum, nickel, silver, zinc, and gold and platinum group metals can be found in sulfide forms. these concentrated ore deposits are considered low grade because of the economic costs associated

problem with gold recovery from sulphide ore: how may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. this latter point is most important. in many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an
