Chelation therapy might be recommended for children with a blood level of 45 mcg/dL or greater and adults with high blood levels of lead or symptoms of lead poisoning. ethylenediaminetetraacetic acid (EDTA) chelation therapy.

This culminates into low grade, fine grain size, complex ore mineralogy, and poor liberation, thus, causing the beneficiation of lead-zinc ore a challenging task. This paper summarizes the classification of ore deposits and different beneficiation techniques that are currently employed for the treatment of lead-zinc ore.

Hence, the treatment of process waters for reuse is often required, but this is not a common practice. Should the removal of ions in low concentrations (<20 ppm of copper, lead, zinc) be required, separations technologies as flocculation-settling or filtration (micro or nano) will not be effective.
