Simultaneous Removal of S and As from a Refractory Gold,
29-04-2019· S and As are common impurities in refractory gold ores and must be removed before gold extraction. Thermodynamic analyses show that it is possible to simultaneously remove S and As by an O2-enriched single-stage roasting, which is confirmed with experimental results from roasting of a gold refractory ore. The range of optimal O2 requirement is narrowMineral Processing Flowsheets,08-03-2016· The flowsheet showed the results obtained from testing a complex lead-zinc-copper-iron ore containing values in gold. Exceptionally high grade and recovery were obtained in this instance.
