Studies Of The Recovery Process Of Rubidium From Polymetallic Ore Tailings In Guanexi Limu

In this paper, the distribution and law of the element rubidium from Limu in Guangxi wereresearched, which pointed out that mine rubidium element is mainly distributed in the magmaticorigin of granite, pegmatite, aplite and quartz feldspar vein-type rock (ore). Single mineral chemicalanalysis showed that the rubidium content can be get as high as0.37%,which determines rubidium ismainly enriched in muscovite ore, and rubidium is the recycling target minerals; for the main metalrecovered from re-election tailings in mine, mica was floated firstly,"one rough three fine threesweep" open closed-circuit flotation feldspar fluorine-free flotation process was conducted, and thenthe flotation reagent usage conditions test was researched. Under optimal pharmaceutical system,mica can be effectively separated from quartz and feldspar minerals, rubidium can be better enriched.Mineral leaching process reaction, the course of the reaction in the mineral leaching process, aswell as the reaction of the main control influencing factors were analyzed, which came out therubidium leaching kinetics equation; which came out the extraction balanced equation, K,△G,△H,△S and other thermodynamic constants, DSC thermal analysis of single mineral and the muscovitewith additives, analysis of mineral surface morphology changement before and after roasting andleaching were conducted by scanning electron microscopy analysisapparent. The effect of calcination time, calcination temperature on the rubidium leaching rate wereexamined by single factor experiment, which came out the best roasting and leaching processconditions. The influencing factors in the extraction and reverse extraction process were examined,which obtained the optimum conditions in the rubidium extraction and reverse extraction. Thisresearch has a certain significance for the comprehensive utilization of metal mine tailings andrubidium resource development and utilization.The environmental problems of rubidium recycling process are analyzed, the existing problems ofthe specific measures are puts forward, an evaluation of social and economic benefits are made.
