Mg(OH)2 recovery from Mg2+-rich brines

Abstract

Desalination plants and saltworks are widely adopted to produce fresh water and table salt. However, these plants produce waste saline solutions that have been mainly handled following the linear economy approach. In the present study, the possible exploitation of waste saline streams is investigated aiming at producing highly pure magnesium hydroxide compounds, thus, turning waste into valuable products as well as reducing the environmental impact of these saline solutions.
