In one embodiment, nitrogen gas (110) is used to prevent contact between the ore and air during comminution of the ore (108) and during flotation operations (114). This invention recognizes that gold in refractory sulfide ores primarily occurs in refractory auriferous sulfides, which are typically the most difficult sulfide species in the ores to float.

The 40 Ar/ 39 Ar dating of sericite from auriferous quartz veins yielded a weighted mean age of 243.4 ± 2.3 Ma, representing the ore-forming age of the Tuwaishan gold deposit. The formation of the shear-hosted gold deposits along the Gezhen gold belt was likely related to the Early to Middle Triassic convergence between the Indochina and South China Blocks.

Auriferous Deposits

Gold and elements of the platinum group metals have been found in several types of deposits around the world. Sometimes, deposits have been worked for their cobble and gravel components and these places have been set up to recover heavy minerals (mainly as black sands) from their host rock. These minerals carry precious metals and they can be recovered by gravimetric devices such as shaking ...
