Evaluation of Lead And Zinc Concentration Tailings As Secondary Mineral Resources
In this work, beneficiation of galenite from lead and zinc processing plant tailings was studied by froth flotation. In the flotation experiments, collector type and amount, frother type and amount, particle size, pH and flotation time were kept constant while solid ratio and depressant dosage were varied. The experimental results revealed that a concentrate of over 45 %Pb content with nearly 80 %Pb recovery was obtained under the optimum conditions from a head sample of that contains 1,16 %Pb and 10,05 % Fe. The Fe content of concentrate was around 3 % indicating 70 % reduction according to head sample.
