If I have a gold ore associated with Quartz SiO2, since quartz's melting point is around 1700°C and the fire-assay can only go up to 1100°C, doesn't this lead to an incorrect concentration result? Are the reagents use to increase the Au extraction from its other compounds? Thank you very much, Clyde.

Extraction. Quartz is extracted from open pit mines. Miners only use explosives on rare occasions when they need to expose a deep seam of quartz. The reason for this is that although quartz is known for its hardness, it damages easily if it is suddenly exposed to a change in temperature, such as that caused by a blast.

Gold readily dissolves in these solvents because of the formation of complex ions that are very stable. Gold (Au) melts at a temperature of 1,064° C (1,947° F). Its relatively high density (19.3 grams per cubic centimetre) has made it amenable to recovery by placer mining and gravity concentration techniques.
