In order to improve the treatment efficiency of thickener in a copper mine of Ecuador，re⁃
duce the transportation cost and reduce the phenomenon of muddy running，the flocculation sedimentation
test of tailings was carried out. The results show that when the slurry concentration is 16.67%，the flocculant
dosage is 20 g/t，and the flocculant BK816F is added，the sedimentation rate of the tailings slurry is the fast⁃
est，and the height of the clear water layer can reach 15 cm after 80 s of sedimentation. When the slurry con⁃
centration is 30%，the sedimentation rate of tailings slurry is generally accelerated with the increase of floc⁃
culant dosage，and the effect of BK816F is the most obvious，which can achieve better sedimentation effect
in a lower dosage and a shorter time. The viscosity of BK816F is the lowest when the mass concentration of
flocculant solution is all 0.1%. All the performance indexes show that BK816F can be used as an efficient
flocculant for the copper mine.
