Grinding Circuit - an overview | ScienceDirect Topics

It is extensively used in closed-circuit grinding operations but has found many other uses, such as desliming, degritting, and thickening. A typical hydrocyclone (Figure 8.12a) consists of a conically shaped vessel, open at its apex, or underflow, joined to a cylindrical section, which has a tangential feed inlet.

Flash Flotation with Closed Circuit Grinding

The reason why you need Flash Flotation in a Closed Grinding Circuit relates to “Recovering your mineral as soon as free” which has long been recognized in ore dressing practice. This not only applies to gravity treatment but also to flotation. For this application the Flash Flotation Cell was developed for use in the grinding circuit and has done a remarkable job in many plants. Flotation ...
