- The aqua regia and chlorination leaching provided a rapid rate of dissolution, however, special attention should be given to strong oxidaion and corrosion of reagents.
- Superior corrosion resistance, no corrosion in acids,alkali and aqua regia.
- It is simple to determine Ag in gold ore by adopting Atomic Absorption Spectrum (AAS) with aqua regia dissolving ore sample and CCL4 extraction it.
- The effect of the sewage sample treated with aqua regia(1+1),acid medium and reducing agent on the determination of the mercury were studied.
- The application of 3% nitric acid and 3% aqua regia yielded good results in nanoscale material geochemical survey in known concealed ore districts.
