Szukana fraza: [Abstract = "The mineralogical and metallurgical information was compared to the material balance for rougher flotation results. These samples showed that copper recovery optimization should focus on the losses of liberated Cu\-minerals and how they are associated with fine particles. The result of variable impeller radial velocity for each flotation cell cascade on metallurgical performance has been explored on a known\-sized and an unknown\-sized base, to gauge the input from the fine particles."]
