Minerals | Special Issue : Flotation Chemistry

Sodium hydrogen sulfide (NaHS) is commonly used as a copper depressant in the selective flotation of copper and molybdenum ores. However, the process is facing health and safety issues because NaHS readily yields toxic hydrogen sulfide gas (H 2 S) under acidic conditions. In this study, Na 2 SO 3 was proposed as an alternative copper depressant. The effect of Na 2 SO 3 on the surface ...

Magnetic and Electrostatic Separation - ScienceDirect

If the susceptibility has a negative value, (i.e., about −10 −5) and a magnet is placed in its field, it is weakly repelled, and the mineral is a diamagnetic mineral.When the susceptibility has a positive value (≈10 −3) then the mineral is paramagnetic. Ferromagnetic minerals are a special case of paramagnetism with very large values of susceptibility; thus materials like magnetite ...
