Bubble size does have a certain impact on flotation efficiency. Smaller bubbles allow for better air dispersion, increasing the bubble surface area and its contact with mineral particles, which is beneficial for flotation and can improve flotation parameters. However, if the bubbles are too small, the rising speed is also very low, which is detrimental. Therefore, bubbles should not be too large during flotation; smaller is better, but they should not be too small, otherwise it will affect flotation parameters, reduce recovery rate, and decrease concentrate quality.
