Glass　ceramic　was　successfully　synthesized　using　goldmine　tailings　as　main　raw　material,　The　frit　preparation　and　molding　techniques,　and　the　nucleation　and　crystallization　processes　were　discussed.　The　results　showed　that　only　one　crystalline　phase,　idiomorphic　diopside,　was　formed　in　shapes　of　small　columns　and　grains.　The　optimum　temperatures　for　melt,　sintering,　nucleation　and　crystallization　were　1350°C,　1160°C,　750°C,　and　860°C,　respectively.
