Instead of nice yellow gold, our gold looks as silver like, as it is mixed with mercury. Heaps of tailings are polluted with mercury and our recovery is such that we cannot see it yellow any more unless it is either microscopic, as such could not be connected to mercury or too large as nugget, as such also did not connect to mercury.
