Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. However, because the Bessel process was used on graphite not gold, silver, copper, lead, zinc, etc, their .. Illustrative, the flotation process is used for purification of potassium chloride from sodium chloride and clay minerals.
