Abstract Scope Copper industry accesses more and more arsenic containing mineral deposits due to the depletion of copper ores. Even in gold industry ore bodies containing significant levels of arsenic are under consideration. In the pyro and hydro process of such minerals, arsenic becomes a major environmental issue to be resolve for the sustainable processing. One of possible industrial routes to minimize the arsenic environmental problem is the stabilization of arsenic oxide into glass phase. In order to understand the fundamental of such stabilization process and design the proper glass composition and operation condition, the thermodynamics of As oxides in the Na2O-CaO-MgO-SiO2 liquid and glass is indispensable. In the present study, the thermodynamic modeling of the As2O5-Na2O-CaO-MgO-SiO2 system and its application to glass composition and operation process design for arsenic stabilization will be presented.
