摘要：

The thermal decomposition of arsenopyrite in the presence of calcium oxide was studied using TG/FTIR. A fairly pure arsenopyrite mineral and an industrial arsenopyrite concentrate were examined in inert and oxidizing atmospheres. The decomposition takes place below 800-degrees-C with the release of arsenic and sulphur in a form that depends on the prevailing atmosphere and on the amount of CaO added. The results also indicated that, with the addition of an appropriate amount of CaO, nearly complete containment of arsenic and sulphur during the decomposition of arsenopyrite may be possible.
