A buddy sent me 30 pounds of black sand, after obtaining a bit of black sludge tried to get rid of some of the base metals before sending in for an assay then the unexpected happened my solution turned a light green. At this point I knew my assay sampled was ruined, so this morning added some bleach.
As you can see from the bottom image the bleach did its work while I was away working on the RV trailer.
