Highly crystallized glass-ceramics from high content gold tailings a one-step direct cooling method.

Highly crystalline glass-ceramics were successfully manufactured a one-step direct cooling method using Shuangqishan (Fujian, China) gold tailings as raw materials. A series of glass-ceramics were prepared by controlling the gold tailings addition and post-treatment. X-ray diffraction results show that the crystalline phase of glass-ceramics samples with high tailing addition content (65-80 wt%) is akermanite phase (CaMgSiO).
