It is obvious that the high gold recovery is achieved at the centre level of NaCN. It is also found that smaller particle size can improve the gold leaching rate. This is because a smaller particle size provides a larger contact surface area between Senanayake solid and Senanayake liquid and therefore increases the gold extraction rate.

Introduction to Mineral Processing

Particle Size. Froth flotation is generally limited to size fractions between roughly 65 and 100 mesh. Particles larger than 65 mesh Tyler (210 micron) are difficult for the air bubble to lift while particles smaller than 400 mesh (37 micron) often will not attach to the air bubble.
