Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste water treatment industries. Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding (a process known as comminution).
