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 •

The impact of classification efficiency on comminution and flotation
Hydrocyclones are the most widely used device for classification in a grinding circuit. However, even the most efficient hydrocyclone has a bypass of fines from the feed to the underflow which reduces comminution circuit performance, as well as misclassification around the cut point. Fine screens classify only according to the particle size, allowing for …
