【摘要】 用数学地质方法，通过电子计算机对３１５１９２个数据的处理，认为金红石自然颗粒较粗，＞０．１、０．２、０．３ｍｍ的分别占９８．８２％、８２．３６％、６４．５５％；据粒度概率分布特征，金红石自然颗粒分为７个总体，分别以０．３２０、０．４３２、０．５４４、０．６６１、０．７６７、０．９３５ｍｍ为界。其成因主要为变质作用及张力的衰减性及波动性。较粗的金红石自然颗粒可使选矿回收率大幅度提高。对矿床经济评价，开发及成因研究等有一定意义。更多还原

【Abstract】 data processing by electro computer and geo mathematics indicate that the natural granules of rutile are course. Granules more than 0.1,0.2 and 0.3 mm occupy 98.82%, 82.36% and 64.55% respectively. The natural granules of rutile can be divided into 7 general parts bounded by 0.320,0.432,0.544,0.661,0.767 and 0.935 mm respectively from the probability distribution of granularity. They are mainly generated by the metamorphism, the decline and fluctuation nature from tensile stress. The natural granules of coarse rutile can make the ore processing recovery ratio to be widely improved, which have a certain significance for economic assessment, exploitation and genetic study of the deposit.更多还原
