遵义仙人岩铝土矿床技术经济评价的模式

位于贵州省遵义县境内的仙人岩铝土矿床，是遵义铝土矿带中规模最大、矿石质量较佳和露采条件良好的主要矿床之一，至今尚未规模开采利用。本文采用分析方法与经济计算相结合的评价模式，对该矿床进行技术经济论证。其计算结果表明，规模开发仙人岩土矿床投资良好，投资偿还期为5．62年，投资收益率17．79％，高于目前国内氧化铝厂参考基准收益率10％～12％的指标。将来矿山、氧化铝厂受益非浅。

Technic and economic evaluating model of Xianrenyan aluminum deposit in Zunyi

Xianrenyan aluminum deposit is located at Zunyixian in Guizhou province, which is one of the main deposits in the Zunyi aluminum ore belt with the largest scale, good ore quality and open mining condition. It is not utilized in large scale. The paper has proposed a set of technic and economic argumentation with the combination of analyzed method and economic calculation. The result indicates that the investment effect is good in the exploitation of Xianrenyan aluminum deposit. Investment compensating period is 5.62 years with investing yield of 17. 79 percent. It is much higher than 10-12 percent of referred benchmark yield of national alumina factory. The mine and alumina factory will benefit great in the future.
