Oxidative Precipitation using Air/SO2
{"Image DocumentName": "Oxidative Precipitation using Air/SO2", "Image ImageDescription": "Oxidative precipitation of Fe and Mn using air/SO2 received much attention from various institutes. Very attractive process option, as SO2 generally available on site from either roaster or S-burner. Fe can be oxidised quantitatively at relatively low pH values (2-2.8) within a reasonably short period (2 g/L within 1 hour) Mn oxidation done at somewhat higher pH values (3-3.5) Co losses to be minimised. No commercial plant yet, Ruashi being commissioned. Test work indicated that gas mixing, sparging and agitation critical. Energy demand for agitation to be optimised.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
