Abstract

Manufacturing blue porcelain produces wastewater containing more cobalt, kaolin, silicates, and organic additives, which is a threat to the environment, as well as a resource recovery opportunity. This review summarizes existing information on the molecular composition of said effluents with a particular focus on cobalt speciation, mineral particle properties, and their interaction with organic ligands. Methods such as ICP-MS, XRD, SEM/TEM, and spectroscopy types offer important information concerning the behavior of metals and clays that will be used in designing targeted recovery operations. The most important methods of resource recovery, such as chemical precipitation, adsorption, electrochemical extraction, and physical separation of kaolin, are critically assessed, and emphasis is placed on integrated multi-stage technologies that maximize efficiency and the quality of a material. The environmental considerations, regulatory issues, and life-cycle are elaborated in order to put recovery strategies in the framework of sustainable manufacturing. The review highlights the possibility of integrating molecular-level knowledge and practical recovery technologies in making blue porcelain wastewater into a source of high-value products. Connecting analytical characterization, treatment procedures, and industrial application, this work offers a baseline of practices of the circular economy in the production of ceramics and lays down the direction of further research into the creation of sustainable and resource-efficient processes.
