The two ores were very similar mineralogically but had a slightly different variety of textures. Cu-Ore 1 contained coarse sulphide to sulphide-barren fragments with both discrete and veined sulphide mineralisation. Another prevalent texture was other microwave-heating minerals (hydrated clays and iron oxides) associated with a soft gangue matrix. Cu-Ore 2 contained massive sulphide to ...

Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver.. Galena is one of the most abundant and widely distributed sulfide minerals.It crystallizes in the cubic crystal system often showing octahedral forms. It is often associated with the minerals sphalerite, calcite and fluorite

Some inorganic sulfides are important ores of such metals as iron, nickel, copper, cobalt, zinc, and lead. Several oxides are formed by sulfur and oxygen; the most important is the heavy, colourless, poisonous gas sulfur dioxide, SO2. It is used primarily as a precursor of sulfur trioxide, or sulfur(VI) oxide, SO3, and thence sulfuric acid ...

Lead commonly occurs in mineral deposits along with other base metals, such as copper and zinc. Lead deposits are broadly classified on the basis of how they are formed. Lead is produced mainly from three types of deposits: sedimentary exhalative (Sedex), Mississippi Valley type (MVT), and volcanogenic massive sulfide (VMS).

There are two general classes of silver ore that have been mined: 1) lead-silver and 2) high-grade silver ores. Both have almost always varying amounts of gold. The lead -silver mines furnish also, as noted above, by far the greater portion of the lead produced in the United States. High grade silver ores normally have considerably less base metal content and often contain significant gold.
