Abstract
The results of researching molecular form, wherein arsenic can be changed to gas phase during processing sulphide gold-bearing concentrates have been expounded. The researches have been realized with techniques of high-temperature mass spectroscopy, scanning electronic microscopy and X-ray spectrometry analysis. The obtained results is the dependable base for development of dearsenization technology of sulphide ores and concentrates with obtaining non-toxic arsenic fumes.
