circulating load gold

Implementation of Computer Control on the Milling Circuit ...

 · The optimum value of the circulating load is a complex function of several vari­ables, the state of which is difficult to estimate. The objective followed is thus to use an EVOP technique for finding the circulating load which maximises throughput at a given product size.

Circulating load estimation in closed circuits

The circulating load can be defined as a process flow (mass or volumetric) of a given material that returns to a unit operation after failing in some selection criteria. This disapproval may be due to an imperfection in the selection equipment or due the material being out of the specification accepted by any subsequent step in the process.
