The zinc dust will be combined with the gold and be called the PRECIPITATE. This precipitate will be trapped on the cloths that form the filtering section of the presses. The solution that has been pumped through the filter presses will not have any gold left in it. At this point the liquid will be referred to as the BARREN SOLUTION.
