摘要/Abstract

摘要： 为实现新疆阿克陶地区高品位锰资源的高效利用,研究综合运用化学分析、光学显微镜、扫描电镜-能
谱分析(SEM-EDS)、X 射线衍射(XRD)及矿物解离分析(MLA)等方法,系统开展了菱锰矿的工艺矿物学研究。结果
表明:矿石锰品位为29. 82%,主要锰矿物为菱锰矿(含量55. 19%),其次为锰辉石、水锰矿和褐锰矿;脉石矿物以绿泥
石和方解石为主。工艺矿物学分析表明,菱锰矿单体解离度较低(33. 02%),与绿泥石、方解石等脉石矿物嵌布紧密,
且绿泥石易发生泥化与罩盖,导致常规物理分选难度较大。研究为该类难选锰矿石的选矿工艺制定提供了重要理论
依据,建议后续优先开发磁选—浮选联合流程及针对性药剂制度,以提升锰回收率并有效脱除钙镁杂质。

关键词: 菱锰矿　工艺矿物学　矿物解离分析　嵌布特性

Abstract: In order to support the efficient utilization of high-grade manganese resources in the Aketao area of Xinjiang,
a systematic process mineralogical study was carried out on rhodochrosite ore using chemical analysis,optical microscopy,scanning
electron microscopy-energy dispersive spectroscopy (SEM-EDS),X-ray diffraction (XRD),and mineral liberation analysis
(MLA). The results indicated a manganese grade of 29. 82% in the ore,with rhodochrosite as the predominant manganese
mineral (55. 19%),followed by manganese pyroxene,manganite,and braunite. The main gangue minerals are chlorite and calcite.
Process mineralogy further revealed a low degree of liberation of rhodochrosite (33. 02%),which is intimately associated
with gangue minerals such as chlorite and calcite. The easy argillization and surface-coating behavior of chlorite also complicate
conventional physical separation. This study provides a critical theoretical basis for designing beneficiation processes for this refractory
manganese ore,and recommends a combined magnetic-flotation process with targeted reagent schemes to improve manganese
recovery and effectively remove calcium and magnesium impurities.
