Lode or Placer: What Difference Does It Make?
September 2014 by Keith BowenThis explains the large difference in particle sizes between placers and hydrothermal lode deposits, but also means that while the mining may be similar in some cases, the sampling and recovery techniques are usually quite different.
The 316 Mining Company has not been all that successful, but does not ever seem to learn from their past mistakes.
Most prospectors understand placer mining a lot better than hard rock mining and don’t realize the amount of work that goes into processing different types of hard rock ore.
These days they employ the use of metal detectors and carefully scan the shattered rocks, hoping to hear that sound we detectorists love to hear.
Carbon, activated charcoal, or “char,” as some old timers refer to it, can be an assayer’s nightmare.
The same day, while two of us were heading to Vancouver to attend the mining convention, two others from our team were headed to Nevada to begin loading the millsite equipment.
Old tailing piles extend for miles. There was still plenty of water flowing here, so WPA members set up highbankers at several settling ponds.
The solution focused on the relative difference in malleability between gold and waste, rather than the difference in density exploited by gravity circuits.
