Chat OnlineThe 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
Chat OnlineAt the same mesh of grind copper nickel and cobalt recoveries were higher and residual sulfur in the tailings was lower with autogeneously ground pulps With ball mill ground pulps the residual sulfur could not be lowered even at increased levels of collector addition An electrochemical interaction between grinding media and sulfide minerals is thought to have a greater effect on flotation
