| Abstract: | The Floatability of copper on the
Modified Hallimond tube depend on lots of
parameters such as dosage and types of collector,
frother, air flow rate, flotation time, and pH value.
All of this parameters give different effect on
floatability. Collectors used for this study are 2-
Mercaptobenzothiazole and Potassium n-Amyl
Xanthate while frothers used are Methyl Isobutyl
Carbinol and Propylene Glycol. pH of the mixture
is varied using common pH modifier which is
lime (CaO). The effects of air flow rate and
flotation time were also studied. Overall, the
result suggests that 2-Mercaptobenzothiazole
(collector) is better than Potassium n-Amyl
Xanthate at pH 10. Xanthate is very good
recovering at pH 11-13 depends on kind of
frother. As the dosage of the both collector
increase, the percentage recovery of Cu also
increase. Methyl Isobutyl Carbinol, (MIBC) is
more effective than Propylene glycol as frother
though the frother is not necessary in hallimond
tube floatability test. As well, increasing in
flotation time and air flow rate also will increase
the percentage of recovery .Although the result
showed copper recovery can be achieved on the
Hallimond tube flotation, further test with
different parameter have to be carried out to
achieve the better result with lower cost and
time.This test makes possible to get a better
indication of how trends will be translated to a
larger scale. |
