Designing flotation circuits for high fines recovery
In reality the circuit is simpler, since each flotation stage can be tailored to suit its feed, and is not disrupted by circulating loads. Theoretically fines float more slowly, but in reality the staged grind float does not need more flotation capacity—in our experience it may need less capacity, since •
