本文首次报道了燃用高GE煤的中国乌兰图嘎和临沧电厂飞灰中Au赋存状态的数据。金以细粒状颗粒赋存于玻璃球表面，大小为n×0.01~0.2umμm。Au颗粒的这些特征证明了Au在电除尘器和袋式除尘器冷却器区域的气相凝聚和沉积在飞灰表面上。
We present the first data on the mode of occurrence of Au in fly ashes from the Wulantuga and Lincang power plants in China, which burn high-Ge coal. Gold occurs as fine-grained drop-like particles with a size ofn*0.01–0.2 μm on the surface of the glass globules. These features of the Au particles are proof for Au condensation from the gas phase and deposition on the surface of fly ash in the cooler zone of the electrostatic precipitator and baghouse filter.
