Milling Ore. Once at the production facility, it is put through a hammer mill to reduce it down to 200 mesh minus in particle size, then fluxed and roasted to reduce ore to an oxide. It is then ball milled with steel balls to a nano particle size, to achieve the highest yield and also the highest concentration level of
Mar 20, 2016 The control of a milling operation is a problem in imponderables from the moment that the ore drops into the mill scoop the process becomes continuous, and continuity ceases only when the products finally come to rest at the concentrate bins and on the tailing dams.
Jan 13, 2016 Here is an Ancient Gold Ore Milling Process used in China in the 1800s. We might use it again after WW3. At the time, 1890, the Author said There is, of course, nothing for us to learn from this imperfect and rudimentary gold-extraction process described here, which is doubtless destined to disappear ere long, before the progress of scientific mining, now making itself slowly felt ...
The project sites have immense above ground tailings piles that can be readily processed. Large mining projects or major ore mill processing plants, where the best ore from 100s of miles around was shipped, operated on these sites. Additional projects are being investigated and negotiated for acquisitions at this time.
