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.

    Jul 09, 2008 While physical methods are very effective and low in cost when applied to the separation of coarse particles, they are much less effective when applied to the separation of fine particles. Also they can not be used to remove impurities which are bound chemically to the coal. These deficiencies may be overcome in the future by chemical cleaning.Jul 09, 2008 While physical methods are very effective and low in cost when applied to the separation of coarse particles, they are much less effective when applied to the separation of fine particles.

    Physical, chemical, and biological methods all aim to oxidize sulfides and preferably produce sulfate ions which also decrease pH value. Wet air oxidation is the most applied method in which, under high temperature and pressure, spent caustic is oxidized by air oxygen.Physical, chemical, and biological methods all aim to oxidize sulfides and preferably produce sulfate ions which also decrease pH value.

Generally, gold can be refined using these two-best-known gold-refining procedures Aqua Regia and gold electrolysis. Both of these techniques can be used to separate gold from other metals. This is because a little piece of other metals in gold can change its properties and value.

As the leach solution percolates down through the rocks, the gold is dissolved into the solution. The solution is processed further to extract the gold.

Strong acids are used to dissolve the impurities in the gold ore and afterwards, are neutralized and washed away, taking the impurities with them. The resulting product is a muddy substance that is almost pure gold 99.999 or 24K. This muddy substance is dried until it is a .
