广西锰矿资源特征及保障程度分析

锰矿是广西的优势矿产之一,查明的资源储量位列全国第一,且资源保障程度高、分布高度集中、开发潜力大.文章根据新一轮重要矿产资源利用现状调查成果,分析了广西锰矿资源禀赋特征和开发利用现状,对锰矿资源的需求及保障程度进行研究.为保障广西锰业的持续和健康发展,提出对锰矿资源实行统一规划,强化矿产资源管理,实行保护性开采,延长锰产业链;对氧化锰矿的开采进行宏观调控,开展资源富集区深部碳酸锰矿勘查,加强低品位碳酸锰矿的可选性试验研究;适当增加进口优质锰矿与国产锰矿搭配使用.

Analysis on characteristics and the manganese resources guarantee level of Guangxi

Manganese ore is one of the superior mineral resources in Guangxi province. The identified reserves is ranked first in China with high guarantee level and the ore deposits are densely distributed thus development potential is great. This article is based on the results of a new round of important mineral resources utilization investigation. Endowment characteristics, current situation of the exploitation and uti- lization of the manganese resources are analyzed and the demands and security degree studied. In order to ensure persistent and healthy development of the manganese industry in Guangxi, some suggestions are put forward： the unified planning of the manganese resources must be conducted; the management strengthened; protective mining implemented and the industrial link extended; the mining of manganese oxide ore macroscopically regulated and controlled; manganese carbonate ore exploration to depth of the Mn-deposit-clustered areas carry out; beneficiation test of low grade carbonate Mn ore strengthened; import of high-quality manganese ore increased to make the mix utilization with the poor Mn ore mined in China.
