how to extract gold from quartz by gravity separation

Extraction of Gold

The extract is transferred to tanks, and the gold precipitated as a powder by addition of zinc. It is then washed out from the bottom of the tanks, dried, and freed from zinc by roasting and fusing. In the electrolytic precipitation of the gold an iron anode and a sheet-lead cathode are employed, the current-density being very low, about 0.5 amp. per sq. metre.

Gold in Quartz

Because quartz and gold may be deposited together across a considerable range of temperatures, not all quartz veins are the same, and there are several different types of gold-quartz deposits. Those deposits formed of solutions that flowed at higher temperatures are distinguished by their own suite of gangue minerals such as tourmaline, apatite, garnet, biotite and amphiboles, in addition to ...
