 · With conversion of copper smelting plants to autogenic melting the problem arises of separate treatment of converter slag (CS). Almost all plants converted to autogenic melting use slag flotation [1,2,3,4,5,6,7,8,9,10].Sometimes they float a mixture of furnace and converter slags after granulation [] of a mixture of CS and original ore in different ratios [].
