The recycled tailings pond water effects of the Mining Company of Gemassa (MCG) flotation plant on the galena recovery, and their selectivity towards chalcopyrite, sphalerite, and pyrrhotite, were studied at bench scale in order to maximize its recyclability.
The Obtained results showed that the recycling of tailings pond water in lead circuit without mixture of fresh water, gave good flotation performances in terms of Pb recovery (75%) and in terms of its selectivity towards the other metals: Pb-Cu (54%), Pb-Zn (60%) and Pb-Fe (65%). This allows the water to be recycled at least four times.
However, the increase of particle size from 100 to 160 μm, currently used at the MCG plant, negatively affects the flotation performance of lead.
