أكمل القراءة· The oxidation of sulfide-based ores is industrially relevant as it facilitates the extraction of valuable metals and eliminates undesired elements from an ore. Even though oxidation can be done thermally (pyrometallurgy), solution-based (hydrometallurgical) methods are currently sought as they represent a more sustainable option. Here, the leaching of a …
أكمل القراءةComparing pyrite and marcasite which are chemically the same (both FeS 2) it can be seen that the relative peak heights for the iron based redox couple compared to the sulfur peaks are significantly different. For pyrite the sulfur signal is significantly smaller than that for iron whereas the reverse is the case for marcasite.
