Abstract

Experiments on beneficiation of low grade lead-zinc sulfide ore in Yunnan were carried out with differential flotation under the selected reagent scheme for separation and recovery of lead and zinc minerals. The results demonstrate that the raw ore with 1.29% Pb and 5.63% Zn has the characteristics of valuable minerals being closely intergrown and finely disseminated. Good technical indexes of lead concentrate with 51.56% Pb grade at 78.58% recovery rate, and zinc concentrate with 46.12% Zn grade at 78.36% recovery rate are obtained, and lead and zinc minerals are effectively separated.

Key words： lead-zinc sulfide ore; differential flotation; lead; zinc; separation
