Jamesonite, marmatite, pyrrhotite and pyrite are the complicated and mutiple-metal sulfide resources to process difficultly in Dachang Mine. Research on the basic theory of flotation electrochemistry and on potential-controlled flotation technology of the sulfide resources can be helpful to develop some new flotation theory and technology of the complicated and mutiple-metal sulfides, and to utilizate comprehensively the mineral resources, and to lower their production cost, and to improve the economical benefits. It is of important theoretical and practical significance.

Comparison of samples of different grain sizes from the Ataiwula property in Dong Ujimqin Qi and Moruogeqin in Abag Qi shows that micro grains of metallic minerals are mixed inhomogeneously in debris carriers.

在东乌旗的阿太乌拉地区和阿巴嘎旗的莫若格钦两地，对比不同粒度的样品，发现金属矿物微颗粒以物理状态不均匀地混合在岩屑介质内。

Along with the development of the natural science people deepen the color knowledge gradually, for example, written language description is not contented to the needs in some field, and the need is quantitative analysis. Color index can show the characteristics of color exactly. For adapting the development, the authors use the metal-bearing ore's color index analysis for the first time through reflectance determining and the color-imetry theory, and analyses 4 turquoises' color index in various color. So the color of turquoise is quantitated successfully.

随着自然科学的发展，对颜色的认识不断加深，从定性到定量颜色指数可以准确地描述颜色特征，笔者利用色度学原理，通过反射率测定，首次把金属矿物颜色指数分析方法应用于绿松石，分析了4个不同颜色绿松石的颜色指数，成功地实现了绿松石颜色的定量表示。

The species and abundance of metal minerals increasing from SE to NW in horizon, corresponding transformation from sulfide altering orebody type to quartz vein orebody type.

同时在矿田水平方向上，由于SE→NW金属矿物的种类和含量呈增加的趋势，由少硫化物蚀变岩型向多金属硫化物石英脉型变化。

The δ〓O for both of them are changed due to water/rock interaction at water/rock weight ratios of larger than 0.1, and the calculation indicates that, in this case, the influence of water/rock interaction on the δD value of the fluid is minor. In the upper part of the geothermal system, the upward ore forming fluid mixes with low temperature groundwater with very low salinity and δ〓O, which may cause the precipitation of metals.

根据氢、氧同位素研究结果，嵩溪银锑矿床的上升成矿流体是由岩浆热液与循环地下水热液混合而成，这种混合成因含矿热液上升到地热系统上部与低矿化度、低δ〓O的低温地下水发生了不均匀混合，这种混合作用导致金属矿物沉淀，但成矿物质是由上升成矿流体带来的。
