我国含钒石煤资源极为丰富,广布于二十个省,我省有四十多个县均有石煤资源,面积达几万平方公里,尤其集中在缺煤的湖区和工业基础较薄弱的湘西地区。岳阳新开公社境内石煤资源极富,早在1960年我所对新开的含钒石煤进行了多年的研究,完成了工业规模以回转窑为主体的盐焙烧提钒工艺试验。由于该工艺设备复杂,技术要求高,动力消耗大,还需要煤气或重油作燃料,建厂投资大,工期长,因此,国内以此工艺建立的钒冶炼厂都迟迟不能建成投产。
China’s vanadium-rich stone coal resources are extremely rich, widely distributed in 20 provinces, the province has more than 40 counties have stone resources, an area of tens of thousands of square kilometers, especially in the lack of coal in the lake and the industrial base is weak Western Hunan. Yueyang Newly Opened Commune has very rich resources of stone coal resources. As early as 1960, I conducted many years of research on newly-opened vanadium-containing stone coal and completed the trial of vanadium extraction by salt roasting with the rotary kiln as the main industrial scale. As the process equipment is complex, high technical requirements, power consumption, but also need gas or heavy oil for fuel, investment in construction, long duration, therefore, the domestic process of vanadium smelters have been delayed to put into operation.
