摘要：
The chain structure of KFeS2 allows exchange reactions to be performed. If potassium is replaced by calcium, the [FeS2] structural framework is retained so that this reaction can be considered as a Soft Chemistry process. It is not the case of the silver exchange which induces a change to a chalcopyrite structure. Potassium can be extracted from KFeS2 but the obtained FeS2 is pyrite. This drastic structural change precludes this reaction to be considered as a Soft Chemistry process.
