A typical metal deposit might contain a few percent of ore minerals (, chalcopyrite or sphalerite), mixed with the minerals of the original rock (, quartz or feldspar). Other sulphide minerals are commonly present within the ore, especially pyrite.

Mining of Minerals and Methods of Extracting of Metals from Ores. METALS ARE VERY IMPORTANT MATERIALS IN OUR EVERYDAY LIVES this page is an introduction to the theory and practice of extracting metals from their naturally occurring ores. Rocks are a mixture of minerals and from these minerals extremely useful metals can be extracted.

in some cases pollution to air and chemical run off.

The first step in recovering metals from their minerals is that of finding orebodies in which metal sulfides are present in a sufficient quantity, and at a sufficient concentration, for mining to be economic.

Mining methods for tungsten ore are not at all exceptional and usually are On the other hand, ore concentrates traded internationally require 6575% WO3. whilst wolframite ore can be concentrated by gravity spirals, cones, tables,

Metals with low chemical activity, such a gold and silver are normally found in their pure state. Copper, tin, lead, and iron are more reactive and must be heated with carbon to extract the metals. Aluminum, calcium, sodium and other active metals are extracted using electrolysis. Copper can be extracted from its ores by reduction.

Concentration or Dressing of the Ore Generally, the ores are found mixed with earthy impurities like sand, clay, lime stone etc. These unwanted impurities in the ore are called gangue or matrix. The process of removal of gangue from powdered ore is called concentration or ore dressing. There are several methods for concentrating the ores.

concentration or dressing of the ore: the ore are usually obtained from the ground and therefore contained large amount of unwanted impurities, the elimination of these impurities from the ores is known as concentration. the concentration of it is done by the physical as well as chemical methods.

Ore is a term used to describe an aggregate of minerals from which a valuable constituent, especially a metal, can be profitably mined and extracted. Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or gangue material.

BBC GCSE Bitesize: Methods of extracting metals. A metal ore is a rock containing a metal, or a metal compound, in high enough concentration to make it economic to extract the metal. Ores are mined. They may need to be concentrated before the metal is extracted and purified. The economics of using a particular ore may change over time.

Geologists use many methods to find mineral deposits that will be profitable to mine. Ores that are close to the surface are mined by surface mining methods. Ores that are deep in Earth are mined using underground methods. Metal ores must be melted to make metals. Many gems are cut and polished to increase their beauty.
