Ferric Sulfate Leaching of Pyrrhotite Tailings between 30

The reaction order with respect to ferric ion was found to be 1 at the high concentration range. SEM images of partially leached tailings confirmed the presence of elemental sulfur around the pyrrhotite particles, which was responsible for the observed non linear leaching kinetics (diffusion control).

Regeneration and purification of spent electrolyte from

Reducing the alkaline concentration to proper levels and extracting Na 2 CO 3 from the spent electrolyte to enable causticisation are the two challenges this work focuses on. Based on the regular dissolution pattern of Na 2 CO 3 in high concentration alkaline solutions, an integrated process of regeneration and purification of spent electrolyte by causticisation is developed in this paper.

Spent Electrolyte Regeneration and Recovery of Associated

The high concentration of alkaline leads to supersaturation and precipitation of these impurity ions. However, the main reason is that the impurity ions are deposited via adsorption, coacervation, coprecipitation, and net capture during the crystallization of sodium carbonate because the concentrations of impurity ions in the spent electrolyte are all milligram grade.
