广东梅县锰矿物质成份的研究

随着我国钢铁工业和化学工业的迅猛发展,对锰矿资源的需求,日益增加.梅县锰矿公司对该县的锰矿地质和锰矿生产做了大量工作.在前人工作的基础上,我们在锰矿资源的调研中,曾对广东省梅县的宝山岗、白沙坪、桃尧大华、宝坑、仙水塘、磔角坑、车陂等地的锰矿体、进行过采样工作.经室内鉴定后、梅县的锰矿石有优质的放电锰矿石和冶金用锰矿石、矿床规模属于中小型.梅县锰矿资源的生产,继续已有20多年的历史,在矿床的质和量方面尚需做更深入的研究,以便为矿山开采和锰矿生产提供更充分的依据.本文是对锰矿物质成分初步研究的部分结果.

A STUDY ON THE COMPOSITIONS OF MANGANESE ORES IN MEI COUNTY, GUANGDONG PROVINCE

This paper introduces the study results on mineral associations and ore textures of two types of manganese deposits which are oxidized Mn ores of eluvial and talus accumulation,and sedimentary-metamorphic quartz-type.Systematic determination has been conducted on 10 species of manganese minerals,e.g.nsutite,manganese nsutite,cryptomelane,hollandite,coronadite,pyrolusite,todorokite,birnessite,braunite,spessartine.Manganese minerals which are fine grained,poor crystallized and similar in properties are distinguished.The mineral associations and chemical variations of Mn ores with 6 kinds of different structure have also been illustrated.
