摘要
这是一篇矿物加工工程领域的论文.新疆某伟晶岩型锂辉石矿中主要目的矿物为锂辉石,伴生有少量的铌钽铁矿,脉石矿物主要为长石、石英和云母等.本文针对该锂辉石矿首先进行了重介质旋流器实验,将重介质选矿的中矿及-0.6mm的细粒级合并作为浮选给矿,将浮选给矿磨细后进行了系统的浮选实验.采用"重介质选矿-浮选"工艺,针对含Li2O 1.68％的原矿,最终全流程实验可获得重介质精矿含Li2O6.5％,回收率51.58％;浮选精矿含Li2O 5.37％,回收率31.94％,两个精矿合并后总精矿含Li2O 6.02％,回收率83.52％.重介质旋流器可以直接产出回收率约50％的高品位精矿,可以抛掉产率约43％的尾矿,可大大节省破碎成本和磨矿成本.
Abstract
This is an article in the field of mineral processing engineering.A pegmatitic lithium polymetallic mine in Xinjiang Province,in which the main target mineral is spodumene,accompanied by a small amount of niobium-tantalite,and the gangue minerals are mainly feldspar,quartz and mica.In this article,the DMS test is carried out for the spodumene ore firstly.The middling of DMS and the fine sample of-0.6 mm are combined as feed for flotation test.After grinding the feed,the systematic flotation tests were carried out.Finally,as to the raw ore containing Li2O 1.68％,by adopting the combined technology of DMS-Flotation,the dense medium concentrate obtained contains Li2O 6.5％and 51.58％of recovery,the flotation concentrate obtained contains Li2O 5.37％,and 31.94％of recovery.The total concentrate contains Li2O 6.02％,and the recovery is 83.52％.DMS for this spodumene ore can directly produce high-grade concentrate with a recovery of 50％,and discard tailings with a yield of 43％,which can greatly save the cost of crushing grinding.
