A pilot-plant for the selective recovery of magnesium and calcium from waste brines

2021

Abstract The problem of brines disposal has raised great interest towards new strategies for their valorisation through the recovery of minerals or energy. As an example, the spent brine from ion exchange resins regeneration is often discharged into rivers or lakes, thus impacting on the process sustainability. However, such brines can be effectively reconcentrated, after removal of bivalent cations, and reused for the resins regeneration. This work focuses on developing and testing a pilot plant for selective recovery of magnesium and calcium from spent brines exploiting a novel proprietary crystallization unit. This is part of a larger treatment chain for the complete regeneration of the …

Development of a pilot plant for the recovery of magnesium hydroxide from waste brines

Waste brines from various industrial processes, mainly from saltworks, are an important source of minerals, such as magnesium, table salt and potable water.
