Figure 7 illustrates the benefit in current efficiency with
the proprietary product. At 4 ppm, the product provides a
1.7% improvement in current efficiency
X-ray fluorescence (XRF) analysis of the cathode cop-
per deposits showed a full two percent increase in current
efficiency and 85% reduction in sulfur impurity for the
proprietary treatment (Figure 8.)

provided smoothing compared to the control runs but less so than the new product
