Abstract:For the low-grade oxidized lead and zinc ores in Lamping area of Nujiang Prefecture, Yunnan Province, the raw ore properties were analyzed, combined with the feasibility study of gravity concentration, and in-depth research on the heavy media beneficiation test and the process test of heavy media combined shaking table-suspension vibration concentrator was carried out. The study of the nature of the original ore shows that the grade of the mixed samples of zinc is 6.35%, lead grade is 1.22%, lead and zinc are the main recovered valuable metals, the gangue minerals are mainly silica and calcium oxide, and contains a small amount of iron, aluminum compounds. The results of the heavy media combined shaking table-suspension vibration concentrator process test show that compared with the single heavy media test, the combined process improves lead metal recovery by about 11 percentage points and zinc metal recovery by about 19 percentage points, which is highly feasible.
