  Ultrasound treatment on tailings to enhance copper flotation recovery

  2016121 · Abstract As ore grades fall, the amount of tailings production for the same copper production is expected to rise. Flotation recovery of copper sulfide from the El Teniente plant has deteriorated in recent years, in this regard ultrasound treatment of tailings for enhanced copper recovery was evaluated in laboratory experiments.

  (PDF) Optimization of reagent dosages for …

  The copper flotation process design is a multi label learning. Before multi label classification and regression, label-specific features for each label need to be selected from the original features. This paper puts forward a multi label feature selection (MLFS) based on domain knowledge and label correlation. In the proposed MLFS, the domain knowledge function …
