Limestone with more than 10 per cent of magnesium is called dolomite. When the percentage rises to 45, it is true dolomite. Dolomite is mainly used as blast furnace flux, as a source of magnesium salts and in fertilizer and glass industries.Ancient iron production - Wikipedia,Ancient iron production refers to iron working in times from prehistory to the early Middle Ages where knowledge of production processes is derived from archaeological investigation. Slag, the byproduct of iron-working processes such as smelting or smithing, is left at the iron-working site rather than being moved away with the product.It also weathers well and hence it is readilyCarbon dioxide - Wikipedia,Carbon dioxide (chemical formula CO 2) is an acidic colorless gas with a density about 53% higher than that of dry air.

Carbon is widely distributed in coal and in the compounds that make up petroleum, natural gas, and plant and animal tissue. The carbon cycle is one ofWhat is "Fool's Gold?" | U.S. Geological Survey,Fool's Gold can be one of three minerals. The most common mineral mistaken for gold is pyrite. Chalcopyrite may also appear gold-like, and weathered mica can mimic gold as well. Compared to actual gold, these minerals will flake, powder, or crumble when poked with a metal point, whereas gold will gouge or indent like soft lead. In addition, actual gold will leave a golden yellow streak(PDF) SME Mining Engineering Handbook, Third Edition,Underground mining method is more selective than the surface mining method counterpart, but the degree of this selectivity depends on the underground mining technique employed ,Cinnabar: A toxic ore of mercury, once used as a pigment,It was used in dental amalgam but is being replaced by polymer resins and other materials. In almost all of its use, mercury is being replaced with less toxic and nontoxic substitutes. Mercury has been widely used in mining to separate gold and silver from ores and stream sediments. Large amounts of mercury were spilled during these operations,magnesium processing | Techniques & Methods | Britannica,magnesium processing, preparation of magnesium ore for use in various products.. Magnesium (Mg) is a silvery white metal that is similar in appearance to aluminum but weighs one-third less. With a density of only 1.738 grams per cubic centimetre, it is the lightest structural metal known. It has a hexagonal close-packed (hcp) crystalline structure, so that, like most metals of thisCobalt | Co - PubChem,Cobalt is a naturally occurring element found in rocks, soil, water, plants, and animals.

Significantly, via the calcium carbonate-generating part of the chemical process, there is a net loss of readily-mobile carbon: we start with twice as much as we end up with.
Halite salt: The mineral Halite information and pictures
Halite, the natural form of salt, is a very common and well-known mineral. It is found in solid masses, and as a dissolved solution in the oceans and in salt lakes. The inland lakes that are rich in salt exist in arid regions, and may also be below sea level without an outlet. These lakes evaporate during dry seasons, causing a recession in the water level and an increase of,,,,,
