Removing the goldbearing rock from the ground is just the first step to isolate pure gold mining companies use a complex extraction process the first step in this process is breaking down large chunks of rock into smaller pieces at a mill large machines known as crushers reduce the ore to pieces no larger than road gravel
Gold refining is a process that involves recovering gold metal from gold ore and converting it to pure gold free from impurities there are several refining systems used to make gold bars electrolyte process chemical treatment smelting and cupellation are some of the common refining methods used to make gold
Deposits and mines in italy in italy most of the mines that existed at the beginning of 1900 have been closed quite large deposits of mercury as cinnabar are present on mount amiata whose exploitation is finished in the 70s of last century and fluorine minerals fluorite were extracted in sardinia mines in silius until few years d iron mines located in cogne in val d
