Lead is one of the most highly recycled and regulated metals. Environmental controls around the processing of lead are extremely important to the continued success of lead as a means of energy storage in the circular economy. This paper describes the different chemistries and technologies used to control waste water emissions from secondary lead facilities. Commonly used technologies include iron co-precipitation, sulfide precipitation and gypsum precipitation. Alternative technologies with future potential are also discussed.
