摘要
我国某大型铷矿床为国内首个独立铷矿床,Rb2O品位为0.12%,总金属量近10万t,矿石中的铷以类质同象形式存在于黑云母中。为高效回收该铷矿资源,采用富集黑云母的方式进行了铷回收试验研究。结果表明,在磨矿细度为-0.074 mm占60%的情况下,采用2粗3精、中矿顺序返回流程处理该矿石,可取得Rb2O品位为0.28%、回收率为65.93%的铷精矿。试验指标较好,可实现铷的高效回收。
A large rubidium deposit in our country is considered as the first domestic deposit with Rb20 grade of 0.12%and the total metal volume of nearly 100 000 t. The rubidium exists in biotite in form of isomorphism. Beneficiation experimentswere carried out to efficiently recover the rubidium. The results showed that at the grinding fineness of 60% passing 0. 074mm,rubidium concentrate with Rb20 grade of 0.28% and recovery of 65.93% was obtained through the flotation process oftwo roughing-three cleaning, and middles back to the flow-sheet in turn. With good flotation index, rubidium can be well recov-ered by this process.
