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 re-select
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?

increased to accelerate this simulation.
