Description / Abstract: This International Standard specifies a lead sulfate precipitation EDTA titrimetric method after acid decomposition for determination of the lead content of lead sulfide concentrates. The method is applicable to lead sulfide concentrates having lead content in the range 50 % (m/m) to 80%(m/m). The method is not applicable to lead concentrates containing more than 1 % (m/m) of barium.
