Jan 23, 2020The characterization of historical mine tailings provides important information for land-management decisions, in particular when considering potential reprocessing activities or the development of an environmental protection program. In addition, outcomes from such characterization may define the scope for a more detailed investigation. The present work

It has been shown, that dextrin is a good depressant for organic carbon and clay minerals with micas as long as the appropriate collector for sulphides are added. Moreover, significantly better flotation of all copper sulphides and pyrite with marcasite was observed, in comparison with flotation test using collector and frother only.

identified at Touquoy included pyrite/marcasite, pyrrhotite, and arsenopyrite (Golder, 2007), all of which generate acidity in response to oxidative weathering. Due to the lack of acidic sulphate salts in the Touquoy mine materials, acid potential (AP) is calculated on the basis of the sulphide sulphur content in a given sample.

Marcasite has the same chemical composition, 58 as pyrite, and looks like it, but is lighter colored and usually occurs in fibrous masses. It is the commoner form in limestones and shales, while pyrite is more likely to occur in igneous and metamorphic rocks. It seems probable that marcasite is due to a more hasty precipitation from cold
