Process for the recovery and separation of arsenic from antimony |
摘要 |
Fume generated by roasting speiss is contacted with an oxygen-containing gas at an elevated temperature for a sufficient time to product arsenic and antimony products which may be separated from each other by means such as condensation. Further, in the roasting of antimony-containing phases (such as speiss) the presence of arsenic can enhance the volatility of the antimony.
