primary and secondary gold mining machines in ore

Mining is only economically viable with a concentration of more than 2.5 grams per tonne. Normally however, quartz seams only contain a gold concentration of one gram per tonne. Secondary Gold Deposits. When primary gold deposits are eroded away by weather (temperature, wind, water) over millions of years, it is referred to as secondary ...

It does not readily combine with other substances and, therefore, does not corrode or tarnish. Because of this property, it is almost always found in nature as pure gold.
