The Kinetics of Pb Removal from Brass Scrap Using Compound

Regardless of the grain size of the Ca-Pb compound, a linear relation was established between the Cu and Zn concentrations. The ratio of Zn concentration to Cu concentration (that is, the slope of the straight line) was 0.51, which almost agreed with the value (0.59) of the Zn/Cu ratio obtained using XRF.
