金属活动态提取技术在多龙铜矿区的应用

Application of Selective Leaching of Mobile Metal forms on the Exploration for Duo-long Mineralize Area,Ali,Tibet

通过对褐铁矿化(铁帽)中Cu、Pb、Zn等元素活动相态(即水溶相、吸附相、碳酸盐相、铁锰氧化物相)的测定,比较主要成矿元素相态空间变化规律,元素各相态变化时与成矿元素总量的关系,从而研究相态变化时对成矿与否的指示意义,以及相态变化对成矿中心的预测。本文通过顺序提取法对成矿元素各个相态逐一研究,结合前人成果从而寻求一种寻找成矿矿床的新的思路。此外与以往不同,本论文采用的样品为初碎样品,主要测试样品表面成矿元素在各个相态中的含量,而非测试全岩含量,意在寻找一种通过表面残余相态成矿元素含量及规律来判断成矿与否以及成矿中心的新思路。

Across text the Cu（Pb）Zn etc elements＇ Mobile Metal forms （ like water dissolved form, adsorption form, carbonate form, iron-manganese oxid form ）of gossan and limonite, to compare the regular pattern in space of the main mineralize elements＇ condition; discover the connection between every conditions and the gross in the main mineralize elements. Accordingly these we can study the denotation of the form-change to judge whether it can be mine and to forecast the central of one mine.By the investigation to every condition of to the mineralize elements, add the efforts of the former peoples＂ so we are try to find a new idea in search of mines. Beside this, the difference of this discourse with others is the samples we used is the first broken sample. The samples we used is mainly to measure the contents of the mineralize elements on the surface, trying to find a new guideline to judge weather it can be a mine and looking for the central of one mine.
