() Complex sulphide ore processing with pyrite

The pulp potential was measured using a gold coil electrode and a standard calomel electrode (SCE) as reference. Another set of measurements was con- ducted with a pyrite electrode in combination with SCE. The pyrite electrode was prepared with a high grade crystal of pyrite following the technique rec- ommended by Adam et al. ( 1984 ).
