Flotation of pyrrhotite to produce magnetite concentrates ...

2013-9-1  Extended flotation time is required to reduce the sulphur level of the magnetite concentrate to below 0.1% w/w. Although the froth appears to have little solids content, it is necessary to continue the process for a time longer than normally expected in order to reduce the sulphur level in the magnetite product to below 0.05% w/w.

RESEARCH FOCUS: Flotation of magmatic minerals

The “flotation” of magnetite has been suggested for other magmatic systems. A single bubble observed in the Bishop Tuff was coated in small magnetite crystals (Gualda and Anderson, 2007), interpreted as reflecting heterogeneous nucleation of bubbles on magnetite, as commonly observed in experiments (Gardner and Denis, 2004).Bubbles and magnetites were coupled in mafic enclaves within ...
