Mineral dressing (= Orebeneficiation) The first process most ores undergo after they leave the mine is mineral dressing (processing), also called ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate ...

Gold ores containing as little as 0.044 ounce (1.25 grams) of gold per ton can be mined at a profit. Magnesium can be removed from sea water at a profit by special methods. Gold, though present in sea water, cannot yet be extracted profitably. Thus, the value of the metal and its chemical properties influence production methods.

The gold content varies depending on the geology of the land, with an estimated average in the earth's crust at 6 000 tons of gold to 1000 cubic kilometers. There are therefore two extraction methods. Prospectors settle on land rich in gold ore and the digging mines are sometimes vast.

The ore often occurs in veins, which are ore-filled fissures in the rock. The veins vary in thickness from only fractions of an inch to several hundred feet. Minerals with no commercial value, called gangue minerals, are usually found mixed with the ore in the vein. Some veins are buried deep within the ground, but others lie close to the surface.
