Jul 17,2021 Fig. 3 : X-ray powder diffraction spectrum of lead-zinc ore sample by trial experimentation. The flotation results are shown in Fig. 4. We can see from this figure due to better liberation an increase in -74 micron particles in flotation feed from 21.5% to 38.5% showed an improvement in lead and zinc recovery.

if lead, zinc and copper are sulphides, the logical process is to produce a pb-cu bulk concentrate, and tails from the pb-cu flotation circuit feed the zinc flotation circuit. in this case, the lead content is much higher than copper content, then it would be necessary to depress lead and float copper. usually, lead and copper requires cleaning ...
the most valuable elements in the run-of-mined ore were lead, zinc and silver, and the main lead and zinc minerals were oxide minerals and the content of sulfide minerals of lead and zinc were small. the processing technology of this kind of ore in general can be divided into technics of floating lead at first and floating the zinc later and

apr 01, 2015 the zinc ore flotation recovery and zinc grade were 84.5% and 24.5%, respectively. 2) when it was used the mixed collector of kax and dda in different concentration ratios of the collectors, the optimum zinc flotation recovery and zinc grade were 82.65 % and 24.1%, respectively, for the mixed collector concentration ratio (kax: dda) of 3:1.
in this case study the only valuable minerals are galena and sphalerite, so the grade and recovery of zinc in the lead concentrates must be reduced as possible. design of experiments (doe)(jacquez, 1998; park, 2007) is a methodology using mathematical principles to design and analysis experiments of a process in different conditions.

after flotation the remaining solution contained 0.5 mg/l cu, 2.5 mg/l pb, 2.6 mg/l ni, 3.4 mg/l cd, 1.5 mg/l zn. ion flotation method can be used to clean process waters produced in flotation ...
as main gangue minerals, calcite, dolomite, and some silicates are present in both ore types. before 1960, the lead-vanadate-containing ore from different ore bodies was processed using gravity concentration. the processing plant for flotation of lead, zinc, and vanadate minerals was introduced by the end of 1961 and closed in 1978.
lead-zinc sulphide ore contains lead sulphide (galena), and zinc sulphide (sphalerite). in the first flotation stage, galena is rendered hydrophobic with an organic collector such as xanthate, while sphalerite is kept from floating by depressants, and in the second flotation stage, activator was used to activated zinc flotation. since the organic regent used are different in the two flotation ...
copper-lead-zinc polymetallic ore was carried out. mineralogical study analysis on mineral consitituents. table 1 lists the mineral consitituents and the contents in the ore . analysis results of the main chemical elements are shown in table 2. the phase analysis results of opper, lead and zinc can be seen from table 3 to table 5, respectively.
