The chemical activating mechanism of UA is that CG can stimulate pozzolanicity more effective than gypsum because of higher solubility and looser crystal structure; but CG has poor property on retardation setting, and this shortage can be solved by mixing with gypsum; CS can offer alkali activity, which can depolymerize silica and aluminum glass, and benefit for other activity methods and overcome the disadvantage of HF on setting time; Sodium sulfate improves early strength greatly but loses the final strength. NF can improve both early and final strengths.

The oxidant 〓 plays indirect role in dissolving gold, and mainly controls the mix potential of Au in the alkaline thiourea solution. In which the "mix potential"is the decisive factor affecting the dissolution of gold. The reaction driving force is enough to have formamidine disulfide oxidize Au to Au〓 at the potential of about 0.4V. And then thiourea molecular complexes with Au〓 ion soon, which causes the fast dissolution of gold in the alkaline thiourea media.
