first the gold ore is crunched up into little pieces then a cyanide solution is used to dissolve the particles of gold. the remaining solid rock and other minerals are filtered out and the gold is precipitated out of the cyanide solution (this
major physical and chemical methods include magnetic separation froth flotation leaching etc. whereby the impurities and unwanted materials are removed from the ore and the base ore of the metal is concentrated meaning the percentage of metal in the ore is increased. this concentrate is then either processed to remove moisture or else used
the three method generally used to extract metals from ores are dependent on their reactivity. the first method is electrolysis which is used for metals like aluminum and magnesium that have a
extractive metallurgy - wikipedia the free encyclopedia. several processes are used for extraction of same metal depending on this is then concentrated using various physical and chemical methods like be used as a feed in another process to extract a secondary product from the original ore.
there are many different methods used to concentrate and refine minerals. the choice of methods depends on the composition of the ore. most of the methods however make use of chemistry to extract the metal from the compound or remove impurities from the final product. we will discuss the extraction of iron from iron ore as an example.
mining of gold: 1) placer mining extracting of gold involving the use of water or dredging 2) panning it is a method of getting gold through separating gold from other materials by using wide shallow pans filled with sand and gravel that may contain gold 3) slucing using a man
