【摘要】：查明錸在礦石礦物中的賦存狀態(tài)是對(duì)錸進(jìn)行綜合回收的前提。以往研究缺乏針對(duì)德興富家塢礦床銅鉬礦石中錸的賦存狀態(tài)研究。對(duì)此,本文通過(guò)化學(xué)分析、巖礦鑒定、電子探針?lè)治觥⒑Y析試驗(yàn)和平衡配分等方法和手段,對(duì)富家塢礦床中蝕變花崗閃長(zhǎng)斑巖型和千枚巖型銅鉬礦石進(jìn)行了系統(tǒng)的工藝礦物學(xué)研究,查明了礦石中錸的賦存狀態(tài)及影響其回收利用的因素。研究未發(fā)現(xiàn)獨(dú)立錸礦物,錸分散分布于輝鉬礦、黃銅礦、黃鐵礦、方鉛礦和鋯石等礦物中,含量范圍為0.001%~0.267%。輝鉬礦為錸的富集和回收的目標(biāo)礦物,其錸含量高達(dá)684×10~(-6),且錸在不同粒級(jí)中與鉬的品位變化具趨同性。對(duì)兩類銅鉬礦石的錸進(jìn)行綜合回收時(shí)需考慮輝鉬礦含量及脈石礦物種類的差異性,分類利用礦石;同時(shí),對(duì)礦石進(jìn)行破碎細(xì)磨時(shí),應(yīng)避免礦石過(guò)粉碎問(wèn)題,以提高+0.023 mm粒段中錸的綜合回收率。
[Abstract]:It is a prerequisite for the comprehensive recovery of rhenium to find out the occurrence of rhenium in ore minerals. Previous studies lack of research on the occurrence of rhenium in copper molybdenum ore of Fujiawu deposit, Dexing. In this paper, through chemical analysis, rock and ore identification, electron probe analysis, screening test and equilibrium partition and other methods and means, The process mineralogy of altered granodiorite porphyry type and phyllite type copper-molybdenum ore in Fujiawu deposit was studied systematically. The occurrence state of rhenium in the ore and the factors affecting its recovery and utilization were found out. No independent rhenium minerals were found, and rhenium was dispersed in molybdenum, chalcopyrite, pyrite, galena and zircon. Molybdenum is the target mineral for the enrichment and recovery of rhenium. Its rhenium content is up to 684 脳 10 ~ (-6), and the change of grade of rhenium is similar to that of molybdenum in different grain levels. In the process of comprehensive recovery of rhenium from two kinds of copper molybdenum ores, the molybdenum content and the difference of gangue minerals should be taken into account in order to classify and utilize the ores. At the same time, the problem of ore overcrushing should be avoided when crushing and fine grinding the ores. In order to improve the comprehensive recovery of rhenium in 0.023 mm particle.
