Yield in ounces estimated on basis of US$20/oz. The evaluation of ore grade in placers is difficult because of the low grade and unusually coarse gold grain size. Extremely large samples of several hundreds of tons must be treated in a mineral concentration sampling plant for the evaluation of a placer ore grade and for flowsheet design. Commonly, this is a gravity concentration plant composed of spirals, jigs, and centrifugal concentrators. Estimates of gold grade by this method may differ greatly from the eventual average gold concentration recovered from operations, with ratios of recovered-to-expected gold content varying from 32% to 149% in one study [12].
