Bronze - Wikipedia

Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (such as aluminium, manganese, nickel or zinc) and sometimes non-metals or metalloids such as arsenic, phosphorus or silicon.These additions produce a range of alloys that may be harder than copper alone, or have other useful properties, such as stiffness, ductility ...

Mining is the extraction (removal) of minerals and metals from earth. Manganese, tantalum, cassiterite, copper, tin, nickel, bauxite (aluminum ore), iron ore, gold, silver, and diamonds are just some examples of what is mined. Mining is a money making business. Not only do mining companies prosper, but governments also make money from revenues.

2. Inclusions Inclusions of a second mineral (or even air!) within a host mineral can also alter a mineral's color. Examples: Prase quartz: Hedenbergite inclusions in quartz give prase its green color. Green quartz: Chlorite inclusions in quartz also cause it to turn green. Jasper: Hematite inclusions can turn jasper red. Milky quartz: Inclusions of very small air bubbles in clear quartz turn ...

Iron in high-fire reduction can yield lovely, delicate iron-blue and celadon green. High-fire, high-iron content glazes fired in reduction will yield glossy dark brown or brownish black. In thin areas, the iron may reoxidize during cooling. Reoxidization will result in those areas turning red or gaining red highlights.

Butte, Montana – The Richest Hill on Earth

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 (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...

Introduction List of Most Common Carbonate Minerals

This is an introduction list that covers the most common carbonates minerals which are compounds of carbon dioxide (frequently called carbonic acid) with oxides of metals. In naming individual carbonates, the name of the metal is used; but if the name of the oxide of the metal is better known, as lime, for example, which is calcium oxide, the name of the oxide will be used instead of the name ...

Vanadium - Wikipedia

Mar 17, 2017· The oxide minerals are compounds of metallic elements plus oxygen, with two prominent exceptions: ice and quartz. Ice (H 2 O) always gets left out of the mineral books. Quartz (SiO 2) is treated as one of the silicate minerals.Some of them are primary minerals that solidify deep in the Earth in magmas, but the most common oxide minerals form near the surface where oxygen in the air and …

Vanadium is a chemical element with the symbol V and atomic number 23. It is a hard, silvery-grey, malleable transition metal.The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) somewhat stabilizes the free metal against further oxidation.. Andrés Manuel del Río discovered compounds of vanadium in 1801 in Mexico by ...
