Development of a novel technology for DSP separation and soda recovery in alumina refineries (2009–2012)

Abstract:

This project aims to develop an effective and economical technology to separate DSP (desilication product) from red mud slurry and also recover the valuable soda from DSP. Soda in DSP represents 60% of soda loss in alumina refineries, and the slow release of soda in DSP also contributes to the long-term alkalinity of the residue. The novel technology to be developed in this project will not only reduce the loss of the soda but also prevent the pollution caused by the release of the soda from DSP, thus important to the alumina refineries economically and environmentally.
