4 Conclusions
The influence of the type and dosage of
poly(ethylene glycol) alkyl ethers on the flotation
performance of model mixtures of carbonaceous copper
shale and quartz was investigated. The results clearly
show that all the used ethers, that is mono(ethylene
glycol) monobutyl C4E1, di(ethylene glycol) monoethyl
C2E2, di(ethylene glycol) monobutyl C4E2, di(ethylene
glycol) monohexyl C6E2, tri(ethylene glycol) monobutyl
C4E3 can be used for separation of carbonaceous copper
shale from quartz by flotation
