the impurities are removed from the iron? the iron ore is converted into pure iron oxide? the waste materials are driven off to concentrate the iron ore
Figure 5.5 shows the cross-section of a copper oxide ore particle that has been leached for approximately 48 h in a sulfuric acid leaching solution at pH 1.5. The copper oxide minerals near the outer rim as well as acid consuming gangue minerals near the rim have been dissolved. It is also worth noting that the penetration depth is …
