ORES OF COMMON METALS

A mineral or rock, which contains enough of a chemical element to make it economically feasible to mine, is called an ore. Ore is used in describing rocks containing a metallic element or elements, and may be used in connection with nonmetallic substances. In nature, the ore minerals are found in veins or in deposits in association with rocks of little or no value. In native ores the valuable element is found free as an element. Gold, silver, platinum and copper may occur as elements. More commonly the element to be recovered is chemically combined with sulfur, oxygen, carbon, silicon or other elements and must be separated from them. The separation of the desired element is done by roasting, smelting, electrolysis or various chemical treatments. Included are BAUXITE-AR, CHALCOPYRITE-MEXICO, MALACHITE-UT/AZ, AZURITE-UT, NV, PYRITE MOSTLY PURE-MEXICO, HEMATITE RED-UT/WY, MAGNETITE-WY/UT, LIMONITE-SD/CANADA, HEMATITE BANDED IRON FORMATION, SIDERITE-SD/CANADA, DOLOMITE PINK-WY, PYROLUSITE-WY, CASSITERITE-SD, SPHALERITE-MEXICO and BERYL-SD/NC.

Sources of Aluminum: 

  • BAUXITE - Product of leaching from aluminum bearing rocks in tropics.

Other Sources:  diaspore, gibbsite, boehmite, and cryolite

Sources of Copper:

  • CHALCOPYRITE - Occurs in hydrothermal veins and replacement deposits.
  • MALACHITE - Occurs in oxidized copper veins as a supergene mineral.

Other Sources:  native copper, chalcocite, bornite, cuprite, chrysocolla, azurite

Sources of Iron

  • PYRITE - Pyrite is formed in both high and low temperature igneous & metamorphic rocks.
  • HEMATITE - Large deposits are formed by leaching or iron bearing rocks.
  • MAGNETITE - Occurs in large beds and lenses in metamorphic rocks.
  • LIMONITE -A weathered product of iron minerals.
  • PYRRHOTITE - Found in deposits associated with basic igneous rocks.
  • SIDERITE - Occurs in concentric layers in shale and clay formations.

Other Sources: goethite

Sources of Lead:

  • GALENA - Found in hydrothermal veins.

Other Sources: cerussite, anglesite, vanadinite, and wulfenite

Sources of Magnesium:

  • DOLOMITE - Replacement mineral after limestone in sedimentary strata.

Other Sources: magnesite, carnallite, and brucite

Sources of Manganese:

  • PYROLUSITE - Develops in deposits from sea floors and lake bottoms.

Other Sources: manganite, franklinite, rhodochrosite, and rhodonite

Sources of Tin:

  • CASSITERITE - Found near granitic rocks in hydrothermal veins.

Sources of Zinc: 

  • SPHALERITE - Occurs in replacement deposits and hydrothermal veins.

Other Sources: smithsonite, hemimorphite, franklinite, and willemite

Alloys:

  • BERYL - Found in granitic rocks and pegmatites.

Other Examples: molybdenite
