    Froth flotation leaching and electrowinning are the most common types of chemical separation. Froth flotation uses hydrophobic and hydrophilic properties to separate the ore from the gangue. Hydrophobic particles will rise to the top of the solution to be skimmed off. Changes to pH in the solution can influence what particles will be hydrophilic.
