Now
investigate the effect of inclusion
size on flotation velocity by selecting different inclusion
sizes.
 If you have access to a printer, print out this page;
 Turn the stir speed to zero and select an inclusion
diameter of 1 µm. This will restart the
simulation;
 After 30 seconds, record the number of remaining particles
and the number of agglomerations
in the table;
 Now turn the stir speed to its maximum value and reselect
1mm to restart the clock;
 Again, after 30 seconds, record the number of remaining
particles and the number of agglomerations in the table;
 Repeat steps 2 to 5 for inclusions sizes of 5, 15, 30
and 50 µm;
 Plot your results on a graph;
 What are your main conclusions?

N.B. Both the inclusion sizes, and their velocities have been artificially
increased to accelerate this simulation.
