Abstract

Described herein is a process for the production of potassium sulfate and ammonium sulfate from syngenite. Specifically, the syngenite is produced from waste liquors and low value minerals and is used to produce valuable secondary products. Specifically, instead of performing the decomposition reaction in one step at high temperature, this process performs the reaction in 2 steps at temperatures lower than the decomposition temperature of ammonium bicarbonate: a first step to reach the equilibrium and produce saturated potassium sulfate brine, and a second step to complete the syngenite decomposition reaction.
