Lead rarely occurs as a native metal in nature. The main lead ore mineral is galena (Table 1), which may contain minor amounts of silver. Galena oxidises to various secondary lead minerals, mainly cerrusite, anglesite and pyromorphite Pb 5 (PO 4) 3 Cl. The chief zinc mineral is sphalerite, which commonly contains

Lead Losses: In Tailings: The lead losses in the tailing varied from 0.12 to 0.47%. Most of the sulphide lead in the tailing was in the form of locked particles, that is, small grains of galena attached to other sulphides or gangue minerals. Finer crushing and froth flotation would enable recovery of most of this lead.
