Fig. 2 shows that as pH increased from 9.0 to 10.5 and then to 11.5, the pyrite recovery obtained from the flotation of the ore with 5 % pyrite decreased steadily from 94.5 to 40.6 % and then to 10.3 %. Hence, a direct link between the decreased pyrite recovery in Fig. 2 and the increased Cu grade in Fig. 1 when pH increased could be drawn. The …

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 ...

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 …

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by

1. Introduction. The flotation process is a separation technique primarily used in mineral processing for the recovery of minerals (Wills and Finch, 2016), that also finds application in other industrial processes such as wastewater treatment and paper recycling (Saththasivam et al., 2016, Vashisth et al., 2011).Separation of mineral particles by …

According to the mineral compositions, these ores can be sub-divided into three main groups including (a) copper-gold ore, (b) copper sulfide ore with moderate pyrite content and (c) massive sulfide copper ores. Copper porphyry ores are the most abundant copper ores; more than 60% of the world's copper production is from these ores.

The recovery of loellingite becomes critical to enriching arsenic, meaning that the flotation requires a collector that can efficiently collect the loellingite. In addition, arsenic distributed in copper matte (7.86%) and metallic copper (5.55%) can be recovered by flotation utilizing conventional copper sulphide mineral collectors.
