There is sometimes that annoying type of impurity in the concentrate that bedevils the refiner. It can be dealt with though. We have a company that for free will rid a concentrate of any metal impurities such as harmful gold, platinum or copper. As you know many of these metals are poisons and can be difficult to get rid of. We will provide a free test on 5 to 50 bulk samples of the concentrates for a heavy metal removal trial. Detectable amounts of heavy metal should exceed 400 Parts per million of species in excess of 13.5 specific gravity. echarter@vianet.on.ca

John, you need to know how much ore was required to produce this 128 pounds of concentrates. Then divide the assay figures (81 oz gold per ton for example) by the concentration factor to get the recovered grade of the ore. Assuming that the sample of ore is a valid sample of the orebody (and it is unlikely to be), you have may handle on the economics of mining the orebody. In reality it would take 20-30 ten ton bulk samples to support even a rudimentary grade estimate for a small mine.
