Abstract

Some complex refractory Lead-Zinc ore features low lead and high zinc,high oxidation rate of lead minerals,mallic minerals and gangue minerals formation inclusions,complex intergrowth of zinc mineral.Lead and zinc selective flotation was been used with agent T9 as floatation regulators of lead or zinc ore,and agent XK-28 as lead mineral collectors,better separation of lead and zinc mineral was achieved.Small closed-circuit test showed indicators of lead concentrate containing lead 49.40%,lead recovery rate of 51.71%,zinc concentrate containing zinc 80.70%,zinc recovery rate 86.32%.
