Copper flotation machines mechanism synthesis

Dec 15, 2020 The flotation of copper from copper-tin alloy was also conducted in an XFD flotation machine with 0.5 L cell volume, under following conditions: natural pH, the pulp concentration is 30%, 300 g/t of ADD and 50 g/t of terpineol for copper rougher; and 100 g/t of ADD for copper cleaner, as shown in Fig. 2. Finally, a rich copper concentrate was
