 · I am thinking that my choices are: 1. Grind the black sands to a powder. (some miners are putting them in cement mixers with ball bearings and pulverizing them while still keeping the micron gold intact) then running them on a shaker table. 2. Smelting to get the gold bead. 3. Grinding to powder then leaching.

Hot bath the black sand, and give it a nice stir. 2. Crushing the Black Sand. Sometimes one black sand particle will merge with several other grains of black sand, and capture some gold in the process. If this has happened to enough extent, you might decide to crush it to extract the gold.

 · The Process of Assaying Black Sands. So, in conclusion, a process has been developed for assaying black sands by using a much lower amount of ore, processing it in a microwave and adding materials to the flux to help convert the platinum group elements, that I believe are in the Ormus form in the black sand, into metals which only show up as …
