Mobile crusher used in gold mining

Favorites / Print /

Gold's average concentration in the Earth's crust is 0.005 parts per million. The technology of extraction is expensive primarily because the process always requires gold mining companies to manipulate large physical quantities of ore for small results. The energy required to heave, grind and process ore is itself valuable, as are the chemicals used in the process, and this places a lower limit on the quality of ore which can be profitably worked in the gold mining process.
At different points concentration of minerals within the earth's crust varies from their average, and it is those variations which produce workable ores for gold mining. Iron, for example, accounts for an average 5.8% of the content of the Earth's crust. It needs to be concentrated by natural variations to about 30% to be considered an ore, indicating a required geological concentration of about 5 times. A lower grade gold ore would contain something like 5 grams per tonne (5 parts per million). So gold ore needs to be concentrated by about 1,000 times above its average dispersion to become viable for gold mining.
