| Abstract: | Technological study on mineral processing of a refractory molybdenum ore in Heilongjiang is carried out.Low grade Pb and Zn existing in the ore can be comprehensively recovered.Valuable minerals are finely disseminated with a high content of layered silicate,so it is easy to slime.A Mo-Pb bulk flotation-middlings regrinding-Zn flotation flowsheet is used in the study.The following results are achieved in a closed circuit test: Mo concentrate grade is 45.22% with 87.04% Mo recovery;Pb concentrate grade is 55.46% containing 3.82% zinc with 75.12% Pb recovery;Zn concentrate grade is 46.12% containing 0.47% Pb with 86.23% Zn recovery. |
