Useful minerals such as gold, copper, zinc and coal are extracted using this method. Hycontrol has been at the forefront of foam detection and measurement for many years. We are used to dealing with applications where the foam is an issue, controlling dosing pumps to eliminate it. However, in flotation, the foam is literally where the money is
Sep 24, 2018 Froth flotation is a physicochemical process that has been used for more than a century in the concentration of copper sulfide minerals . This process is based on the wettability of copper mineral particles to recover the mineral species of interest and depress unwanted gangue. A very important aspect of flotation is its kinetics.
Dec 02, 2019 Froth flotation method is a kind of gold mining process that makes the useful minerals adhere to the bubble for achieving the gold separation with the flotation reagents based on the difference of physical and chemical properties of mineral surface. The froth flotation method can be used to deal with the nonferrous ores, such as copper, lead ...
Gold Flotation Circuit. Froth flotation is a physico-chemical separation process. Separation is principally based on differences in surface hydrophobicity. However, particle size and density have a significant impact. Initial flotation patent and application was developed for
