| 摘 要： | 为保证云南钢铁工业可持续发展,解决矿石资源的不足,从分析截止2002年底保有资源量数据入手,研究尚未上表的铁矿资源现状,发现全省上表98处产地保有的35.52亿t储量中,仅有7.91亿t为当前可应用储量。应从补勘升级上表D级储量(3亿t)、择优勘查未上表的矿区(2亿t)、试验-研究3类矿石的选矿回收(菱铁矿石1亿t,鲕状高磷赤铁矿石1亿t,高磷非鲕状赤铁矿石0.5亿t),合计可新增可应用矿石7.5亿t,加上已有的7.91亿t,可应用矿石最终达15.41亿t。再加上第二轮国土资源大调查铁矿的新发现,立足省内,扩大进口,必将缓解云南铁矿资源紧缺的现状。

| Abstract: | In order to gurantee the iron and steel industry sustainable development in Yunnan province, figure out iron ore deficiency, started with data analysis of hold reserves cut-off at the end of year 2002, studied iron ore resource present situation not on the reserve table, it is discovered that only 791 million tons applicable currently among 3.552 billion tons of totally 98 mineral lands of the reserve table. It is necessary to upgrade D level reverves by addition exploration, and pick out mine lands which are not on reserves table for studing, testing their ore dressing recycling of three type of iron ore metahohmannite ore 1 billion ton, high phosphorus bearing oolitic hematite ore 1 billion, high phosphorus beating nomolitie hematite ore 0.5 billion ton. It will added up to 7.5 billion tons of available iron ore. Plus the existed amoun 7.91 billion ton, the available iron ore amount can reach to 15.41 billion tons. Superadd new discoveries iron mine from the second time surveying of land and resoune of China, extend import and based up on local province, it will be turn the edge of the situation of lacking of iron ore in Yunnan province. |
