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

ABSTRACT: Highly crystalline glass-ceramics were successfully manufactured via 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 (Ca₂MgSi₂O₇). By contrast, the main phase of 60 wt% and 55 wt% tailings addition samples is diopside (CaMgSi₂O₆) crystalline phase. In addition, although glass-ceramics have typical fracture characteristics of brittle materials, the crack propagation in the fracture process is disturbed by grains, resulting in the
