What is the best, most accurate method to assay the precious metals in black sands? I super concentrate my sluice cons with a clean up sluice, then run the black sands on a miller table to get the very fine visible gold out down to -300 mesh. My neighbors at their placer mine have had their...

Advances in processing technology, together with a degree of gold release through ageing of the ore over many years, often provide gold recovery in the range 50–60% (headgrade around 0.4–0.5 g/t), which is sufficient to cover the low processing costs and make a positive contribution to the profitability of an operation.
