摘要/Abstract

摘要： 针对江西新余某铁钴矿中钴品位低、嵌布粒度细、回收难度大的问题,本研究开展了系统的选矿综合利
用试验。通过工艺矿物学分析,明确了钴主要赋存于硫化物中,据此提出了“先浮选回收硫钴、后磁选回收铁”的原则
流程。通过系统的条件试验,确定了最佳工艺参数:磨矿细度为-0. 074 mm 占65%;采用碳酸钠(500 g/ t)作抑制剂、
硫酸铜(50 g/ t)作活化剂,以及新型三元巯基组合捕收剂CJ-1(150 g/ t)。结果表明,CJ-1 相较于传统丁基黄药能同
时提高硫、钴精矿的品位与回收率。闭路试验最终获得两种合格产品:硫钴精矿的硫、钴品位分别为37. 44%和
0. 32%,回收率分别为95. 54%和60. 35%;磁铁精矿的全铁和磁性铁品位分别为60. 50%和56. 47%,回收率分别为
66. 28%和96. 42%。本研究为该类低品位铁钴矿资源的综合利用提供了可行的技术方案。

Abstract: Aiming at the problems of low cobalt grade,fine dissemination grain size,and difficult recovery in an iron-cobalt
ore from Xinyu,Jiangxi Province,this study conducted systematic mineral processing tests for comprehensive utilization.
Process mineralogy analysis showed that cobalt mainly occurs in sulfide minerals,and thus a principle flowsheet of “flotation
first to recover sulfur-cobalt minerals,followed by magnetic separation to recover iron” was proposed. Through systematic conditional
tests,the optimal parameters were determined:grinding fineness of 65% passing 0. 074 mm;Using sodium carbonate
(500 g/ t) as inhibitor,copper sulfate (50 g/ t) as activator,and a novel ternary sulfhydryl composite collector CJ-1 (150
g/ t). The results showed that compared with traditional butyl xanthate,CJ-1 could simultaneously improve the grade and recovery
of sulfur and cobalt concentrate. The closed-circuit test finally obtained two qualified products:the sulfur-cobalt concentrate
with S and Co grades of 37. 44% and 0. 32%,and recoveries of 95. 54% and 60. 35%,respectively;The magnetite concentrate
with TFe and mFe grades of 60. 50% and 56. 47%,and recoveries of 66. 28% and 96. 42%,respectively. This study provides a
feasible technical route for the comprehensive utilization of this type of low-grade iron-cobalt ore resources.

Key words: iron-cobalt ore,flotation,magnetic separation,composite collector,comprehensive utilization
