摘要讨论了能源工业中金属的潜在来源。讨论是基于两个主要的含金属废物从发电厂：灰，炉渣从燃烧过程中和废催化剂从选择性催化还原氮氧化物与氨，被称为SCR。介绍了以浸出法为主的金属回收工艺的组成、方法及其应用前景。固体煤燃烧废物是各种化合物如二氧化硅、氧化铝、氧化铁和钙的来源。在废SCR催化剂的情况下，主要考虑两种金属：钒和钨-工业催化剂的基本组分。
Abstract The potential sources of metals from energy industries are discussed. The discussion is organized based on two main metal-contains wastes from power plants: ashes, slags from combustion process and spent catalysts from selective catalytic NOx reduction process with ammonia, known as SCR. The compositions, methods of metals recovery, based mainly on leaching process, and their further application are presented. Solid coal combustion wastes are sources of various compounds such as silica, alumina, iron oxide, and calcium. In the case of the spent SCR catalysts mainly two metals are considered: vanadium and tungsten – basic components of industrial ones.
