摘要

针对攀西地区微细粒级钛铁矿作为矿泥丢弃的问题,进行了强化微细粒级钛铁矿的预富集研究。采用高梯度强磁机、离心选矿机、悬振锥面选矿机进行微细粒级钛铁矿的预富集,并分别与浮选组成联合选别流程。通过对比分析,获得了微细粒级钛铁矿最佳预富集工艺。结果表明:强磁、离心、悬振预富集精矿回收率分别为38.92%、65.57%、35.56%,悬振预富集精矿粒度及矿物组成较"离心"优,有利于后续浮选作业;"悬振+浮选"流程简单,开路浮选试验获得TiO_2品位47.39%、回收率24.93%的钛精矿;悬振预富集工艺为微细粒级钛铁矿最佳的预富集工艺。
For micro-fine particle ilmenite of Pan-xi region was always discarded as the slime,strengthening the preconcentration process of micro-fine particle ilmenite was studied by means of high gradient magnetic separator,centrifugal separator and hang and vibrate of cone separator.Then the three pre-concentration methods were combined with flotation separately,and the best pre-concentration process was finally obtained with the contrastive analysis of separation indices.The results are showed as follows;Firstly,the concentrate recoveries of high gradient magnetic separation,centrifugal separation and vibrative sepatation are respectively 38.92%,65.57%and 35.56%,and the size and mineral composition of pre-concentration by vibration is better,which is helpful for subsequent flotation.Secondly,the process of "vibration +flotation" has the advantage of simple flow,and the grade and recovery of TiO_2can be respectively achieved 47.39%and24.93%after open circuit flotation.Finally,vibration is the best pre-concentration technology for the micro-fine particle ilmenite.
