Comparing lead and copper activation on pyrite with ...

Jul 01, 2021  In general, pyrite oxidation generated iron and sulphur oxidation species which inhibited the adsorption of lead and copper ions on pyrite surface. Lead ions had stronger affinity to oxidised pyrite than copper ions but pyrite flotation required a higher amount of lead-activating products than copper-activating products.
