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
