Analyzing the Characteristics and Available Attributes of Skarn Gold Deposit Tailings

Skarn gold deposit tailings are a kind of tailings which are difficult to be utilized effectively. Taking skarn gold deposit tailings from Hubei province, in China, as an example, this chapter has tested and analyzed the tailings, studied the characteristics and available attributes of the tailings, and provided scientific and efficient utilization approaches of tailings in the area of building materials further. The results show that major mineral phase in the tailings is quartz, particle sizes of the tailings mainly existed in 10–100 μm, and the tailings have no pozzolanic activity. As a result, this kind of tailings can be used for building sand and can be used as auxiliary cementing material for concrete based on mechano-chemistry.
