摘要
本文研究和分析了我国铀矿资源的特点,总结了花岗岩型、火山岩型、碳硅泥岩型、砂岩和含铀煤型以及其他类型铀矿床矿石的可选性及其规律,指出:我国各类型的铀矿床矿石都有可能采用放选、重选、磁选、浮选、筛选等选矿技术或采用多种选矿-冶炼联合流程来有效地提高水冶供矿品位和质量,回收有用伴生元素,从而可明显地降低铀水冶成本,提高开发铀矿床的经济效益。对于如何进一步提高铀水冶中的经济效益,作者提出了三点结论和五点建议。
In this paper, the characteristics of domestic uranium resources are studied and analized, and the ore dressing possibility and the principle ore processing patterns of granitic, volcanic, carbon-siliceous-muddy, sandstone and lignite uranium-bearing and other deposits are summarized. It is pointed out that the suitable ore dressing flowsheets for the ores of all kinds of deposits can be used possibly with the technologies of radiometry, gravity, magnetic separation, floatation and screening, and the manifold combined dressing-hydrometallurgy circuits can be adopted to improve the grade and quality for ore feed in hydrometallurgy and recover associated elements effectively, so that the uranium hydrometallurgical cost can be decreased obviously and the economic benefit of uranium deposit can be increased. The conclusions and suggestions are made for how to further enhence the economic benefit in uranium hydrometallurgy.
