Abstract:

This research work deals with the upgrading of lead in Sabon Layi lead-zinc ore using gravity and froth flotation beneficiation methods. Analysis of the chemical composition reveals that this crude ore contains 38.76%lead and other related minerals such as 29% silica, 22.80% Sulphur, 2.76%Zinc, 4.17%CaO and others in traces; these related minerals are impurities that hinder the lead grade found in this ore from appreciating. Fractional sieve and the grain size result revealed that the liberation size of the ore is at -710+500µm. At this sieve size, the lead –zinc ore was subjected to four different beneficiation methods using five kilograms (5kg) each as charge on Wilfley shaking Table, Humphrey spiral concentrator, Air floating Machine and one kilogram (1kg) for froth flotation. Resulting products –Concentrate and tailing from Processing were analyzed. The grade and weight of the resulting mineral were used in calculating percentage recovery of each applied process; which was used to ascertain the best method.
