Popis:	The nitrogen dioxide formed from the traditional gold recovery process would cause hazard i.e. air pollution and profile some risk on safety. The research intent is to identify and develop a suitable new method with `eco-friendly' and `Green' philosophy that could be applied for in-house gold recovery process. This problem relates to the quality control of each methods used by the refiners. An area of concern would be on the suitability and feasibility level of the proposed recovery method and how it can be introduced and implemented by the traditional or small scale jewelry workshop at their premises. A full cycle of physical and chemical testing via traditional and sophisticated methods have been conducted to derive and validate findings and conclusions.
