Flotation Circuit: Concentrate Grade and Recovery -

2013-6-19  Flotation Circuit: Concentrate Grade and Recovery. The texture of particles within a flotation cell play a pivotal role in both mineral recovery, and the grade, in the flotation concentrate. Theoretical curves can be generated based on particle mineralogy and texture to indicate the maximum grade-recovery possible for
