The following two categories influence the success of the separation process: 1) Keeping the funnel from plugging by pre-classifying. 2) Keeping the magnet from becoming overloaded. 3) Minimize losses. This may be an iterative process since adjustments will need to be made during the separation process.

Periodically, (on the order of 1 – 2 days) the wash plant is shut-down and the gold is removed. The concentrate may then be subjected to further, more refined concentration, with gravity separation techniques such as jigs, shaking tables, gold centrifugal concentrators and pinched sluices, and possibly magnetic separation if …
