| Abstract: | To solve the problem of copper lead separation caused by similar surface properties and flotability of copper lead minerals, this paper selected an environmentally friendly high-efficiency selective inhibitor BK520 to conduct an experimental study on the separation of copper lead from a mixed concentrate of copper lead. The study found that the use of BK520 effectively reduced the content of copper in lead concentrate, and obtained lead concentrate withthe lead grade 74.85%, lead recovery rate 92.79%, copper grade 2.61% and copper concentrate with copper grade 21.23%, copper recovery rate 89.86%, lead grade 5.34%. |
