Some of the tailings are from the cyanide/carbon process other talings are from a ball mill mercury process. I have taken around 50 kilos of each and run them through a popandson sluice. I then assayed the concentrate which gave us a more than decent return. I am not a chemist or even an expert with gold mining.
Currently all our investments are related to developing equipment and solutions that can process a much higher volume of tailings at a lower cost. "I think in the next 3-5 years, it will be possible to process of such volume on a cost-efficient basis."

tailings in impoundments or free-standing piles, backfilling underground mine workings and open-pits, subaqueous disposal, and the most common method, the disposal of tailings slurry in impoundments. Modern tailings impoundments are engineered structures for permanently disposing of the fine-grained waste from mining and milling operations.
This rudimentary piece of mineral processing equipment uses pulses of water to suspend the particles in water. As the pulses dissipate, the particles settle in the bottom of the jig. Particles with a higher specific gravity (like gold) settle faster than those with a lower specific gravity, effectively separating the gold so it can be collected.
