Abstract
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 Chemist ry process. It is not the case of the silver exchange which induces a change to a chalcopyrite structure. Potassium can be extracted from KF eS2 but the obtained FeS2 is pyrite. This drastic structural change pr ecludes this reaction to be considered as a Soft Chemistry process.
