一、我国铝土矿资源开发利用情况 1.我国铝土矿储量及特点 我国铝土矿资源丰富,分布广泛,全国有19个省、市具有规模大小不等的铝土矿矿床。经普查、详查、勘探,已上报全国储量平衡表的铝土矿区(点)为300多个,保有储量为23亿吨。在我国铝土矿分布的主要省份,尚有潜在的远景储量。根据现有资料初步分析,远景储量约有16亿吨左右。我国铝土矿矿石类型以一水硬铝石为主,具有高铝、高硅、低铁和中等铝硅比的特点。通过对
First, the development and utilization of bauxite resources in China 1. China’s bauxite reserves and characteristics of China’s bauxite rich in resources, widely distributed, there are 19 provinces and cities nationwide with different sizes of bauxite deposits. After census, detailed investigation and exploration, more than 300 bauxite areas (spots) have been reported to the national reserve balance sheet with a reserve of 2.3 billion tons. In the major provinces where bauxite is distributed in our country, there are potential long-term reserves. Based on the preliminary analysis of available information, the prospective reserves are about 1.6 billion tons. China’s bauxite ore type to a diaspore, with high aluminum, high silicon, low iron and medium aluminum-silicon ratio characteristics. Pass right
