  Flotation separation mechanism for secondary copper …

  202225 · Ethyl isobutyl xanthogenic acetate (EIBXAC) was used as a novel collector in the flotation of secondary copper sulfide minerals owing to its ability to separate copper and sulfur. The collectivity and selectivity mechanisms of this novel collector were investigated using single-mineral and artificial mixed-mineral tests, combined with …

  A new perspective on copper oxide flotation: Synthesis and …

  202391 · Abstract A novel chelating collector, phenylethyl hydroxamic acid (BEHA), was synthesized by hydroxylamine method by increasing the carbon chain on the basis of benzohydroxamic acid (BHA). The application of this reagent could eliminate the sulfurization process and directly floated copper oxide malachite, achieving clean …

  The Challenges and Prospects of Recovering Fine Copper …

  202256 · Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered …
