摘　　要：微波是一种频率在300MHz～300GHz的电磁辐射,微波技术在冶金工业中的应用研究主要在矿物的加热、干燥、预处理等方面,包括脱硫、氧化物还原、浸出和冶金废弃物处理等方面.通过对石煤钒矿进行微波预处理,考察了是石煤钒矿的升温特性、失重率等因素,然后对微波预处理后的石煤钒矿进行浸出实验,与没有进行微波预处理的钒矿进行对比发现,不同的微波预处理方式均能够提高浸出率,微波氧化预处理加热5min,石煤钒矿的浸出率与微波不氧化预处理的钒矿浸出率提高4.58%.Microwave is an electromagnetic radiation with an frequency between 300MHz～300GHz.The microwave technology in metallurgy application research is mainly in heating,drying,oxide reduction,mineral processing such as the pretreatment of refractory gold and waste treatment,and metal recovery.The stone coal vanadium ore grinded was dealt with the microwave pretreatment in this article.In order to study the factors such as the heating-up characteristics and weightlessness rate of this ore,the ore by pretreatment was carried on the leaching experiments.Compared with the vanadium mine with different microwave pretreatment,the results showed that every different microwave pretreatment was able to improve the leaching rate.As the ore pretreated by microwave with oxidation heating for 5minutes,the leaching rate was improved almost 4.58%compared with the leaching short of oxidation pretreatment.
