Multi label feature selection for copper flotation process …
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 …

60 Centuries of Copper: The Flotation Process
The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the ...
