最近在美国科罗拉多举行的一次铀矿冶技术讨论会认为:美国的铀矿工业有下述发展趋势: 1.破磨系统自磨和半自磨机逐渐代替常规破磨流程,因为它投资和经营费用都较低。假如对老流程处理的矿石推行这种新技术,必须经过试验和进行经济上的比较后决定取舍。因为铀是顺磁性物质,正在研究用磁选 A recent uranium mining and metallurgy technical seminar held in Colorado, USA, stated that: Uranium mining industry in the United States has the following development trends: 1. Broken grinding system Self-grinding and semi-autogenous grinding mills gradually replace the conventional grinding process because it invests and operates. The costs are low. If this new technology is implemented on the ore handled by the old process, it must be decided through trials and economic comparisons. Because uranium is a paramagnetic material, magnetic separation is being studied.
