INFLUENCE OF LEAD NITRATE ON CYANIDE LEACHING OF

mechanisms with lead nitrate. Lead nitrate passivizes the pyrite by forming a hydroxide (Pb(OH) 2) layer on pyrite surface reducing the dissolution of pyrite. Dissolution of pyrite forms a sulfur layer on gold causing inhibition of gold dissolution. Thus, in presence of lead this layer is less important.
