依据未来稀土供应情况,为预测美国稀土的供应前景,建立起基于网络数据库和稀土地理可视化工具。通过4种不同的经济因素确立了稀土需求的5种不同情况:4种经济因素为国际贸易政策、温室气体排放法规、采矿环保法规及稀土技术适用比的变化等;5种不同的需求情况是美国目前的需求水平、低需求水平、中等需求水平、高需求水平和日本目前的需求水平等。最可能发生的情况是,基于目前国际稀土需求状况,加快开发美国国内现有稀土资源的开采提取加工运营。对于稀土需求的5种不同情况,本文通过注明稀土氧化物(REO)矿床位置的地图,高效地进行描述。
According to the future supply of rare earths, in order to predict the prospects for the supply of rare earths in the United States, a database based on network and geo-visualization tools for rare earths are established. Through four different economic factors, five different situations of rare earth demand have been established: four economic factors are the changes of international trade policies, greenhouse gas emission laws and regulations, mining and environmental protection laws and regulations and the ratio of rare earth technologies; five different kinds of demand are The current level of demand in the United States, the level of low demand, the level of medium demand, the level of high demand and the current level of demand in Japan. The most likely scenario is that based on the current international demand for rare earths, accelerate the development of existing extraction and processing operations of rare earth resources in the United States. For five different scenarios of rare earth demand, this article describes it efficiently using a map that indicates the location of the rare earth oxide (REO) deposit.
