Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents. The selective separation of the minerals,A comparison of the flotation of ore from the Merensky,,The dry ground sample exhibited much faster flotation kinetics than the wet ground samples, while the wet ground samples showed higher concentrate grades and slightly higher recoveries. The samples obtained with dry milling conserved more energy in the form of defects, and displayed activated particle surfaces, onto which reagents easily adsorbed. In the samples obtained from dry milling, some,
