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 fresh copper oxide mineral surfaces exposed during crushing and grinding have a significant effect on subsequent flotation [23], [24], [25], [26].Many dangling bonds exist on fresh mineral surfaces because of destruction of the original lattice bonds, and the copper oxide mineral surface often shows strong polarity because of the existence of ionic bonds.
Both IPETC and W34 are used in the concentrator which is processing a high-pyritic Cu ore simulated in this study. In addition, IPETC is a widely used Cu-selective collector against pyrite in copper flotation ... Copper flotation with 5 and 25 % pyrite feed grades.

The flotation process may be considered an interactive system consisting of many chemical, operational, and equipment variables. Changing any one of these variables causes an overall system response change. This study examines the effects of simultaneously changing the operating variables of: (1) frother concentration and air flow rate, and (2) frother …
