    In my first gold mine we noted that the solution plus solids gold leaving the leach circuit was 2/3rds of what was entering. This soon resulted in suggestions of massive theft by us, the mill crew. The first time that we had to drain a tank I went to the bottom with a camera, a sample bag, and a measuring tape.
