摘要
近20年微波能在许多领域得到了应用和发展,但在冶金过程中的应用还处于起步阶段.本工作主要回顾了微波能在矿物处理和金属提取、回收及材料制备过程中(如加热、磨碎、氧化物矿碳热还原、浸出和冶金废弃物处理等方面)的研究结果和进展情况.尽管在这些方面已有许多研究成果,展现出微波在冶金过程应用的一些优点,但对微波与矿物和金属相互作用的机理及一些现象,仍存在一些认识上的分歧或不明之处.目前,提高微波能的转换效率、研制大功率微波发生器和设计高效的反应器,仍是微波工业化应用的关键.
Microwave processes have been rapidly developed for the last two decades in many areas, but the application of microwave in metallurgical processes is just at the initial stage. This paper presents a review on the research and development results of microwave technology applied in mineral treatment, material preparing process and metal recovery operations such as heating, comminution, carbothermic reduction of oxide mineral, leaching and some of metallurgical waste treatments. Despite in this area a significant number of research studies have been carried out and many results obtained, which exhibits a lot of advantages in metallurgical processes. The mechanism of interaction of microwave with minerals and materials and understanding of some phenomena occurring in a microwave-assisted process are still not explained clearly, so that more investigation will be needed in the future. The conversion efficiency of microwave energy, high power microwave generator and designing efficient reactor are key problems to be overcome for improving industrial applications.
