Separation techniques are based on differences in the physical or chemical properties of the gangue and the ore. These differences may include differences in density, particle size, magnetic properties, or solubility.
What are the differences between the gangue and the ore that separation techniques are based on?

Separation techniques in ore processing are based on the differences in physical and chemical properties between gangue and ore. Ore minerals are economically valuable and have distinct characteristics like higher density, specific gravity, or magnetic susceptibility compared to gangue minerals. For instance, ore minerals may be more susceptible to magnetic fields or have different solubilities in specific liquids. These differences form the basis for techniques such as gravity separation, magnetic separation, and froth flotation, allowing the selective separation of ore minerals from gangue. Effective separation enhances the concentration of valuable minerals, optimizing metal extraction processes in mining and metallurgy.
