I had a batch for someone recently, and they ran pretty low. Less than a gram,per lb. The real pain is, they have to have all of their base metal dissolved to get the gold. It ends up being a lot of dissolving in AR, allowing values to cement, careful decanting, and repeating. Over, and over, and over and over and...
Its hard to break even when chemical cost and waste treatment is considered.
