我国锰矿资源开发利用现状及勘查对策

The Current Situation of Developing and Utilizing Manganese Mineral Resource in China and the Prospecting Strategy

我国虽是世界上主要锰矿资源国和产锰国之一，但锰矿石的显著特点是“贫、细、杂”，因而制约着我国锰业的发展。矿产分布相对集中，以地台型为主，具有多时代，多层位分布特点，锰矿成因类型以海相和热水沉积为主，具多成因成矿作用特征。针对我国富锰矿供矿能力差，保证程度低，供需矛盾日益尖锐，但资源潜力大，找矿远景好等形势提出了加强优质富锰矿的勘查工作等１０条锰矿勘查和开发利用对策。

China is one of major owners and producers of manganese ore worldwide, but the remarkble feature of her manganese mineral resource is “lean grade, fine sized grain and disordered deposit,” which obstructs development of the manganese industry, Furthermore, the gathered distribution of China′s manganese mines is characterized by prevailing of platform pattern, multi era and multi layer distribution. In China, high grade manganese ore is in short supply without guarantee, leading to a sharp contradiction between the supply and demand. However, the resources in potentiality and propective in the future for available deposit is large. With regard to the above, suggestions as reference are made for prospecting, developing and utilizing manganese ore.
