  • 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 metal in finely disseminated particles which aggregate
