Principles of Extractive Metallurgy
What is Extractive Metallurgy ? Deals with extraction of metals from its naturally existing ore/minerals and refining them Minerals: Inorganic compounds with more than one metal in association with non-metals like S,O,N etc. Naturally existing minerals are sulphides, oxides, halides like: Hematite (Fe2O3), Magnetite (Fe3O4), Chalcopyrite (CuFeS2), Dolomite

10 mg/L combined iron and manganese, a clarification step is typically required prior to filtration. A combined iron and manganese concentration of 8 mg/L will generally result in a filter run time of less than 24 hours for sand/anthracite filters as well as greensand-type filters. The clarification process reduces the amount of solids that must be
Different Types of Iron Ore - 911metallurgist.com
Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.

to fossil fuels, coal, and metal mining (Matthews et al., 2000:107). The amount of waste produced depends on the type of mineral extracted, as well as the size of the mine. Gold and silver are among the most wasteful metals, with more than 99 percent of ore extracted ending up as waste. By contrast, iron mining is less wasteful, with

Historically, geophysical technique (magnetic) was first used in Sweden in the 17th century for prospecting iron ore (Reedman, 1979). Geophysical techniques gained more acceptability in the early 1923 (Gupter, 1986) because of exploration for crude oil. Relevance of Geophysics across the world is as a result of oil and solid mineral exploration.
