近年来,我国稀有金属工业发展迅速,对稀有金属精矿原料的需求呈逐年快速增长趋势,供需矛盾日益突出。我国虽然拥有丰富的稀有稀土矿产资源,但部分稀有金属资源现状并不理想,易选的单一矿物资源日趋减少,由于品位偏低或选冶困难而难以加以利用。随着我国高新技术的快速发展,稀有金属冶金及其应用技术也得到相应的快速发展。
In recent years, the rapid development of China’s rare metal industry, the demand for raw materials for rare metal concentrates showed a rapid growth year by year, the contradiction between supply and demand have become increasingly prominent. Although our country has a wealth of rare rare earth mineral resources, the status of some rare metal resources is not ideal. The single mineral resources that are easy to select are declining day by day, which are hard to be utilized due to the low grade or the difficulty of the metallurgy. With the rapid development of high-tech in our country, rare metal metallurgy and its application technology have also been correspondingly rapid development.
