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

    Chlorite and serpentine are common magnesium-containing gangue minerals in copper sulfide flotation. In this study, sodium alginate, a natural hydrophilic polysaccharide, was introduced as a selective depressant for these gangue minerals. Micro-flotation tests were conducted on both single minerals and synthetic mixtures. The flotation results showed that sodium alginate could
