中国锰矿的现状与展望

THE SITUATION AND PROSPECTS OF CHINA'S MANGANESE ORE DEPOSITS

新中国成立迄今,已累计探明锰矿石7.17亿t。中国锰矿床有4种类型:海相沉积型、沉积受变质型、层控型和风化型。锰矿以地台型为主,地槽型次之。锰矿具有多时代,多层位的特点。矿石贫,富矿短缺。多数矿区已开发利用。钢铁工业要求锰业同步发展。今后应加强我国中西部地区锰矿的勘查与开发,重视两种资源的利用。

Since the establishment of the people's Republic of China, a total of 7. 17 hundred million tons of manganese ore has been verified. In China, manganese ore deposits can be divided into four types. They are marine sedimentary, metagenic, stratbound and weathering deposits. Manganese ores are dominated by platform type with geosynclinal type taking second place. And they have the characteristics of multi-periods and multi -layers. Ores are meagre in China which is short of ore shoot. And most of mining areas have been developed. Iron and steel industry is demanding manganese industry to have e-qual pace of development. Finally, the author emphasizes that the exploration and development of manganese ore in central and western parts of China should be strengthened and the utilization of the two kinds of resources should be stressed.
