在獲得美國能源部超過700萬美元撥款之后，首席研究員兼礦業(yè)工程教授Rick Honaker能夠深入研究創(chuàng)造這種新材料?！懊绹茉床宽?xiàng)目的主要目標(biāo)是生產(chǎn)出稀土元素含量至少達(dá)到2%的精礦，”Honaker說道，“我們已經(jīng)超越了這一目標(biāo)?！?/p>
他表示，該提取工藝成功采收出超過80%的給料中存在的稀土元素。從干燥的整塊來看，精礦包含超過80%的稀土元素，以及超過98%的稀土氧化物。此外，常用于國防、高新技術(shù)和可再生能源領(lǐng)域的釹和釔在整個(gè)精礦中占比超過45%。
同時(shí)，通過這一新的采收工藝，有效將鈧與其他元素分離。該稀土元素常用于航空和照明領(lǐng)域，可以濃縮為單獨(dú)產(chǎn)品。
Honaker團(tuán)隊(duì)正在進(jìn)行每小時(shí)四分之一噸的移動稀土采收試點(diǎn)工廠項(xiàng)目，上述突破性工藝只是該項(xiàng)目的其中一部分。
