Ores. Zinc ores are widely distributed throughout the world, although more than 40 percent of the worlds output originates in North America and Australia. The common zinc containing minerals are the zinc sulfide known as zinc blende or sphalerite , a ferrous form of zinc blende known as marmatite S, and a zinc carbonate known as calamine or smithsonite .
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite, hematite, goethite, limonite or siderite. Ores containing very high quantities of hematite or magnetite are known as quot;natural orequot; or quot;direct shipping orequot;,
characteristic crystalline form. Ores are a mixture of minerals: they are processed to yield an industrial mineral or treated chemically to yield a single or several metals. Ores that are generally processed for only a single metal are those of iron, aluminium, chromium, tin, mercury, manganese, tungsten, and some ores of copper. Gold ores

Ores. Aluminum is the third most abundant element on Earths surface. Only oxygen and silicon are more common. Earths crust to a depth of 16 km contains 8 percent aluminum. Aluminum has a strong tendency to combine with other common elements and
