Selective froth flotation concentration of antimonite ore ...

2020-4-16  Optimisation tests were carried out to measure how much of antimony concentrate can be recovered during flotation. It can be deduced from the optimisation tests that increase in dosage of reagents such as collector, activator, frother and promoter results in increase of recovery of antimony. The results are summarised in figure 4.0 below:

Current processing technology for antimony-bearing ores

1989-1-1  The lead-antimony sulphides appear to have properties resembling those of galena, which implies poorer flotation at high pH and the possibility of depressing them with dichromate [i]. Where dichromate is used for subsequent separation of a copper-lead concentrate, this means that the lead-antimony minerals will wind up in the lead concentrate.

Current processing technology for antimony-bearing ores

1989-1-1  The original intention was that antimony flotation should be followed by arsenic flotation with CuSO4 activation, with a view to recovering any remaining "refractory gold". However, this process ran into difficulties and was not put on steam. The quality of the antimony concentrate can be seen from the figures in Table 3.
