Zinc Ore - an overview ScienceDirect Topics

Zinc oxide is prepared commercially by two methods: the American (or direct) process, which uses zinc ore and concentrate, and the French (or indirect) process, which uses zinc metal. Some 54% of US zinc oxide production is from zinc ore and concentrate (American process), 33% from slab zinc (French process) and 13% from secondary material.

Zinc - Wikipedia

Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity .

Where are zinc ores found?Zinc ores are widely distributed throughout the world, although more than 40 percent of the world’s output originates in North America and Australia.How are zinc ores recovered?Zinc ores are recovered by many mining techniques, ranging from open-pit mining (mainly in the case of oxidized ore bodies, which are located closer to Earth’s surface) to the normal underground methods (used for the more deeply located sulfide ores).What is first stage of iron?The first stage is the removal of iron as a solid residue in the form of either jarosite (a basic ferric sulfate) or the oxides goethite or hematite. This is then followed by cementation with zinc dust to remove other metallic impurities (including copper, nickel, cadmium, cobalt, and germanium) from the solution.

What minerals are found in lead?Lead and zinc ores are usually found together with gold and silver. A lead-zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals.What materials are removed from lead refining?Lead refining operations generally consist of several steps, including (in sequence) softening, desilverizing, dezincing, bismuth removal, and final refining. Various other saleable materials may also be removed from the bullion during these steps, such as gold and silver, oxides of antimony, arsenic, tin, and copper.Where is lead found in nature?It is bluish-white, very dense, and has a low melting point. Lead is found in veins and masses in limestone and dolomite. It is also found with deposits of other metals, such as zinc, silver, copper, and gold. Lead is essentially a co-product of zinc mining or a byproduct of copper and/or gold and silver mining.What is lead made of?It is also found with deposits of other metals, such as zinc, silver, copper, and gold.

Complex ores are also the source of byproduct metals such as bismuth, antimony, silver, copper, and gold.Is lead mined?Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist. The use of underground or surface mining techniques depends on the proximity of the ore body to the surface and the individual characteristics of each ore body determine the exact mining method.What minerals are found in mining industry?Energy and Environmental Profile of the U.S. Mining Industry 6.

Sphalerite often contains trace to minor amounts of cadmium, indium, germanium, or gallium.What is the color of sphalerite?Occasionally it will be transparent with a vitreous luster. Sphalerite's streak is white to yellowish brown and sometimes is accompanied by a distinct odor of sulfur. Occasionally it streaks reddish brown. One of the most distinctive properties of sphalerite is its cleavage.What is the dispersion of sphalerite?Sphalerite has a dispersion that exceeds that of all of the popular gems and is three times higher than the dispersion of diamond. Dispersion is the ability of a material to separate white light into the colors of the spectrum as it passes through the material.
