中国铬矿资源2010年保证程度与前景

THE SUPPLY LEVEL AND PROSPECT OF CHINESE CHROMIUM RESOURCES IN 2010

至1993年底,我国已勘查的铬矿区有56处,累计探明铬矿石储量1305.3万t,主要分布于西藏、新疆、内蒙古等省区。贫矿与富矿(Cr_2O_3>32％)大体各占一半。多为中小型矿床。矿床成因主要为岩浆晚期矿床。冶金工业生产不锈钢是铬矿石的最大消费领域。按不锈钢与钢产量比,和我国铬矿生产能力测算,2010年只能满足国内铬矿石需求量的15％,其余要靠进口解决。西藏是国内找铬矿的最佳远景区。

Up to the end of 1993.56 chromium mining areas had been explored in China, mainly distributed in Tibet, Xinjiang and Inner Mongolia provinces and so on. with 1305. 3 ten thousand tons of total explored reserves. Medium and small scale deposits are in majbr, with almost half poor ores and half rich ores(Cr2O3>32%). The genesis of the deposits are mainly late-magmatic deposit. Chromium mining ores are most used in producing stainless steel in metallurgical industry. According to the ratio of the output of stainless steel and steel and the capacity of producing chromium ores, it is estimated that the output of chromium ores will only meet 15% of the domestic demands for it and the shortage will depend on importing from other countries. Tibet is the best prospective area for finding chromium ores in China.
