Minerals Free FullText AcidGangue Interactions in Heap Leach Operations: A Review of the Role of Mineralogy for Predicting Ore Behaviour

Heap leaching accounts for a fifth of global copper production, sourced primarily from porphyry ores, yet metal recoveries are often not optimal. Gangue, and its interaction with acid, plays an important role in such processes. Thus, a proper understanding of gangue minerals present in the ore, their textural relationships relative to particle size distribution, reactivity with acid under

Gangue an overview ScienceDirect Topics

Gangue minerals associated with sulfiderich tailings include various aluminosili e minerals such as chlorite, smectite, biotite, muscovite, plagioclase, amphibole, and pyroxene. Their contribution to acidneutralization reactions has been examined in a number of field studies and through controlled laboratory experiments.

Flotation of acidic minerals AMERICAN CYANAMID CO

This invention relates to the concentration of minerals by froth flotation, more particularly to the beneficiation of ores by floating acidic gangue therefrom. Beneficiation of ores by froth flotation, using a ionictype reagent to float one or more components from the residue has become a well known procedure.
