Abstract

The present invention relates to a two-stage process for Separation in a coal leaching process Silicon/Aluminum based Compounds from Spent Hydrochloric Acid, in which the solution is heated in a first stage to a temperature of around 80 °C to convert the unstable silicon tetrachloride to silicon oxide, and treating the acid with Sulphuric acid to remove alumina based compounds. The Silicon chloride is converted to silicon oxide/hydroxide by reacting with oxygen present in the water, and wherein the regeneration comprises mixing of acid with Sulphuric acid for alumina separation.
