Most of you guys know I was prospecting for diamonds in Wyoming about 12 or 13 years ago. And that it quickly came about there was little water available there. So, a long battle ensued to find a way to recover gems, dry. In that process I started into dry recovery of minerals. Back in January I applied for a patent on a unit that accomplishes that goal...including gems. but, me being me, I'm never satisfied, so while waiting to hear from the patent office, I kept trying to improve the design. One such was trying to recover gold from black sand. I had a breakthrough yesterday, and the linked video was of the machine recovering gold from black sand. The gold is 30-100 mesh. The black sand is a blend of sizes. The machine is designed more for prospecting than mining. The idea is for you desert guys to be able to see any gold you may be finding, without resorting to packing water. With a fine, small brush, and a bit of effort, it would be easy to end up with clean gold.
