· Minerals are mostly extracted to isolate metals like gold, silver, copper, iron, lead, mercury, etc. Also, they are extracted to isolate radioactive substances like plutonium, uranium, etc. Besides these, claylike materials like silicarelated, bentonite, talc, steatite are also extracted. What are minerals used for? Minerals are used for many purposes in human life. Some of them are ...
Horsetail plants were often used by miners in the past as a guide to where gold might be found. It can tolerate the existence of heavy metals in the soil, which has made people believe gold may be nearby. Ironically, the horsetail plant also had a practical use for prospectors during the gold rush. It was primarily used for washing pots and pans.
Mostly used in ceramic industry, but is considered the only source in Iraq for alumina in the future. Bentonite: About 22 million tons of Camontmorillonitic clay are found in Anbar Governorate. At present it is mainly used for oilwell drilling after onsite Naactivation. A plant for Naactivation is needed with 75000 t./year production capacity.
Iron is a metal extracted from iron ore and is hardly ever found in the free state. Iron is used in the production of steel which is not an element but an alloy, a solution of different metals and some nonmetals particularly carbon. Uses of iron. It is used to manufacture steel and also used in civil engineering like reinforced concrete, girders etc. Iron is used to make alloy steels like ...
Green plants use iron for nitrogen binding. Phytoplankton, some of the smallest ocean creatures, depend so heavily on iron that the amount of iron present in water limits the amount of phytoplankton that can survive. Toxicity At normal levels, iron is not deadly to any aquatic animals, but at higher levels when iron does not dissolve in water, fish and other creatures cannot process all the ...

· Iron ore is the main ingredient in steel, which makes up 95 percent of the metals used in the world per year. Two billion metric tons of raw iron ore are produced in a year. The world''s largest single producer of iron ore is Brazilian mining company Vale, which produces over 350 million tons of iron ore annually.
Iron ore is almost exclusively mined by surface operations. The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods. However a few underground iron ore mines are also in operation around the globe. The decision for employing surface mining or underground mining is dependent on the proximity of the ore body to the .
Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult. Treatment of the roasted ores was done by normal methods such as amalgamation or ...
