摘要
甘肃某铷多金属矿中主要矿物成分比较简单,以长石、石英、云母为主,铷主要以类质同象形式分布于钾长石、锂云母中,矿物中铌、钽主要以铁铌锰矿、钽铁铌锰矿和铌铁钽锰矿形式存在。该矿石云母嵌布粒度范围广,嵌布关系复杂,重选难以回收,本试验研究确定采用浮选回收。在对该铷多金属矿进行矿石性质研究基础上,采用磨矿-脱泥-浮选工艺流程回收矿石中的锂云母,可获得Rb2O品位0.75%,回收率为28.31%的云母精矿。该试验研究结果可作为开发利用该类铷多金属矿的锂云母回收利用的基础技术依据。
The main mineral composition in a rubidium polymetallic ore in Gansu is simple, among which feldspar,quartz,mica are the main elements. Rubidium mainly exists in lithium potassium feldspar,and lithia mica. Tantalumand niobium mainly exist in the form of iron, manganese ore, iron tantalum and niobium, tantalum niobium iron man-ganese ore and manganese ore. The disseminated extent range of the mica ore is wide and the disseminated relationis complex, so it＇s difficult for gravity separation. The method of flotation was adopted in the test. based on the basicstudy of the ore properties of the polymetallic ore, the process of gringding-desliming-flotation was adopted. The micaconcentrate with the Rb20 grade of 0. 75% and the recovery of 28.31% was obtained. The test results can providetechnical reference for the development and utilization of 1 lithia mica. of this kind of polymetallic ores.
