In the various gold rushes of the nineteenth century, many prospectors used gold panning as a means to make their ...
C = Weight Recovered of Concentrate c = Assay of Concentrate T = Weight of Tailings t = Assay of Tailings. Let's solve an example; Find the percentage recovery when the weight recovered of concentrate is 9, the assay of concentrate is 7, the weight of tailings is 3 and the assay of tailings is 5. This implies that; C = Weight Recovered of ...
