| 中文摘要: |
| 铷金属是非常重要的稀有金属之一,不仅在军事工业和科学技术领域,而且在民用领域有着广泛的用途.随着我国国民经济高速增长,对铷矿产品需求不断加大.我国最近在内蒙古锡林浩特石灰窑地区发现一大型花岗岩型铷多金属矿床,其初步探明的铷总金属量超过8.7×105 t ,Rb2O平均品位0.163%.矿石中铷主要赋存于云母类矿物和微斜长石中.由于长石中的铷很难提取,为高效回收该铷矿资源,本研究采用富集云母类矿物的方式进行了铷回收实验研究.结果表明,矿石在浮选探索实验中, 随着混合胺用量或水玻璃的增加,铷粗精矿的回收率逐渐提高,当混合胺超过150 g/t或者水玻璃超过1 200 g/t后,回收率增幅较小,确定混合胺用量以150 g/t或水玻璃用量以1 200 g/t为宜,最终可取得Rb2O品位1.59%,回收率约为62.92%的铷精矿.实验指标较好,可实现铷的高效回收. |

| Rubidium metal,which is one of the most important rare metals,has not only been widely used in military and science-technological fields,but in civilian areas.There is an increasing demand of rubidium mineral products with the rapid growth of the national economy.Recently,a large scale of granitic rubidium polymetallic deposit with an initiallly explored total amount of >870 000 tons and average grade of 0.163% have been found in Shihuiyao region,Xilinghot city,Inner Mongolia,China.Rubidium mainly occurs in mica minerals and microcline.In this study,a research on the experiments of rubidium recovery of this deposit was conducted;due to much difficulty in extracting the rubidium in the feldspar,the way of enriching mica minerals rather than feldspar was adopted in order to efficiently recover the rubidium ore resources.The results showed that in the flotation beneficiation experiment,the recovery rate of rubidium crude ore increased with the amounts of mixed amine or water glass,but this increase would be smaller when the content of the mixed amine was more than 150 g/t or that of the water glass was greater than 1200 g/t.In this sense,the amounts of 150 g/t mixed amine or 1200 g/t water glass would be appropriate,which ultimately could produce a type of rubidium ores with 1.59% grade of Rb2O and 62.92% recovery rate.The experiment index is reasonable,and thus can realize the efficient recovery of rubidium. |
