At last , based on above , the mine - exploiting model , which might made the recycling of titanium among vanadic titano - magnetite best , was figured out by using of optimum principle 最后，在此基础上，利用最优化原理，建立了使钒钛磁铁矿中钛回收率达到最佳的矿山开采模型。

Based on the above research , the generalization reason of panzhihua vanadic titano - magnetite was discussed preliminarily and rhythmic magmatie deposit , which is a new thought , was put forward 在此基础上，对整个矿床的成因进行了初步探讨，提出了韵律式岩浆矿床这一新观点。

Taking it for example that zhujiabaobao section of panzhihua vanadic titano - magnetite deposit , the paper detailedly analysed its change regularity in ore texture and structure , mineral composition and content , ore chemical composition , mineral chemical composition , rare element " s change feature of rock and ore , exploding temperature of mineral inclusion . on the basis of above , the feature of rhythmic texture of ore body in panzhihua vanadic titano - magnetite deposit was researched 本文以攀枝花钒钛磁铁矿朱家包包矿段为例，详细分析了该矿段中矿石组构、矿物成分及含量、矿石化学成分、矿物化学成分、岩石及矿石稀土元素变化特征、矿物包裹体爆裂温度等的变化规律，进而研究了攀枝花钒钛磁铁矿矿体中的韵律结构特征。

Through researching the rhythmic change regularity of ore texture and structure , mineral composition and content , rare element " s change feature and the exploding temperature of mineral inclusion , combining the theory of magmatic ore - forming , the forming process of panzhihua vanadic titano - magnetite deposit could be divided into four periods : rock - forming period , main ore - forming period , hydrothermal period and surficial processing period 通过对矿石组构、矿物成分及含量、稀土元素变化特征、矿物包裹体爆裂温度的韵律式变化规律的研究，结合岩浆成矿理论，将攀枝花钒钛磁铁矿矿床的形成过程划分为四个期：成岩期、主成矿期、热液期、表生期。
