Fig. 4 (a) shows the concentration of tracer at
the outlets after 10 sand 15 s of tracer injection.
The asymmetrical flow patterns can be seen from the
pictures. Fig. 4 (b) shows the RTD curves for two
strand outlets. The two strand RTD curves are different
apparently. The minimum breakthrough time
t min is 44 sand 36 s , and the average residence time t;
is 268.4 sand 271. 7 s respectively. Fig. 4 (c) shows
the inclusion flotation rates for two strand outlets.
The inclusion flotation rates are different, being
51. 27% and 35.54% respectively. The average flotation
rate is 43. 41 %.
