One final note about centrifugal concentrators for gold recovery is that they provide very low concentrate mass yields, often less than 0.05%, and consequently very large mass concentration ratios, exceeding 5000:1, for the largest units. Hence, these units are ideally suited for gold as it occurs at less than 20 g/t in most ore bodies.Web
