Whey contains more than half of total solids present in the original milk, which includes 20% of the proteins, most of the lactose, minerals and water soluble vitamins. In this study, selective separation of whey components by Aphron flotation (separation of ultrafine particles by micro-bubbles) has been investigated. It has been shown that it is possible to recover valuable components of whey by flotation method instead of vaporization.
