However, there is great disagreement about the metallogenic factors. For Shuidong gold deposit, the ore-forming fluid may come from deep mantle [9-11] or basin construction water [12], or from mixed sources [9, 13]; the ore-forming materials of the deposit may originate from Emeishan basalt [14], or mixed sources [9, 13].

Once we know the concentration, we have to understand the current gold recovery processes. 3.2. Gold ore processing. The routes for metal production depend on the type of ore. Generally, gold can be obtained both in native form or in tellurides (Valero and Valero, 2014). In both cases, the comminution process is essential.

Most of the time, the gold is like tiny glittery specks inside the quartz, making it a fun but challenging treasure to find. The value of the gold found in quartz depends heavily on the amount of gold present. Some specimens boast visible, concentrated gold veins, making them valuable collector's pieces or even commercially viable for extraction.

Separation of Gold - The extracted ore is crushed and ground to smaller pieces; Recovery of Gold - Chemicals are used to dissolve the gold particles so as to separate them from the unwanted rock material; Purification of Gold - The gold-rich concentrate is further refined to obtain pure gold metal.
