    Other articles where Gangue is discussed: copper processing: Mineral processing: from the waste materials, or gangue. In cases where the next step is leaching (most frequently in the case of oxide ores), complete liberation of the copper minerals is not always necessary; the ore needs to be crushed and ground only to the extent required to expose the surface of

    Previous studies speculate that hydroxo species present in flotation pulps at pH > 9, particularly those of polyvalent cations, selectively adsorb onto gangue minerals. Such species supposedly enhance the depressive action of carboxymethyl cellulose (CMC) onto gangue via an acid-base interaction between the positively charged mineral surface and the negatively charged CMC molecule.

    The 87 Sr/ 86 Sr ratio measurements in Mississippi Valley-type gangue minerals, and host marine carbonates ranging in age from upper Cambrian to Mississippian, show that in northwestern Ohio, where the mineralization is sparse, the minerals precipitated from fluids in local isotopic equilibrium with the host carbonates in which the minerals were emplaced.

    To negate the hydrophobic minerals tendencies to float, depressants are used. They physically adsorb onto the surface of gangue minerals rendering the particles hydrophilic and "non-floatable". The use of depressants allows for higher precious metal recovery and grades and can improve the economics of downstream processing (e.g. smelting costs)

    The liberated minerals of interest also associate with specific collectors, chemicals that yield strong hydrophobicity, in contrast to the unwanted gangue material that usually remains hydrophilic. Hydrophobic surfaces have an affinity for media other than water, such as air bubbles in froth flotation, and oils in agglomeration.
