Sep 24, 2018The Flotation Process. Until quite recently copper ore had to be handpicked 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
