Jinduicheng molybdenum mine, the Department of magmatic hydrothermal China's large molybdenum deposit. Its ore-forming material originates from the medium-shallow acid intrusion-per quartz- potassic granite porphyry (Jinducheng granite porphyry). At present, the types of ore-bearing rocks can be divided into two series: one, granite porphyry and sporadic distribution of Yunyingyan formed by its alteration; second, sub-volcanic rocks formed by shallow intrusion of basic magma— The diabase- basalt type, which has been replaced by green lithology, forms a series of altered rocks of biotite and chlorite, known as Anshan shale. There is no essential difference between the two ore-bearing rocks in mineralization, ore-forming materials, ore properties. However, due to some differences in the operation of the ore-bearing hydrothermal fluid and the chemical composition of the ore-bearing surrounding rock, there are some differences in the quantitative relationship between the ore properties, the main elements and the components. The main elements in various types of ores are MO, the associated main elements are Re, and secondly, there are Cu, Fe, S, Pb, In, Ti, and the like. Among them, Re, S, Fe, Cu and other enterprises have achieved effective comprehensive utilization in production. Cu and Pb are harmful impurity elements. Among them, Cu has been effectively inhibited in the production process, and it has become a good benefit. It has achieved good recovery and achieved good results for comprehensive utilization. Although Pb content is very small, it is a separate mineral. The form is present in the molybdenum ore and is simultaneously entered into the molybdenum concentrate by mechanical mixing, which has become a harmful element in the molybdenum production in recent years. The associated In and Ti elements are too low to be used at present. The mine has been selected and produced for nearly 40 years, and the depth of exposure has reached the middle waist of the ore body. With the increase of the depth of mining, the harmful degree of Pb is likely to increase, and the occurrence of lead is comprehensively studied. Distribution law, mineral inlay relationship, Pb element surface and depth variation, Pb “concentration zone†division, process flow and grinding fineness should be the primary research topics in current enterprise production. According to the requirements of the lead reduction contract test, Party A requires Party B to work on the main contents of the rock ore work: to identify the ore material composition, structure, lead occurrence status and grain size of the Jindengcheng granite porphyry and Anshan shale. Cloth and multi-element analysis of raw ore, molybdenum- copper lead phase analysis, etc., have reached the basic goals and requirements. Among them, breakthroughs have been made in the occurrence, lead distribution, grain size and inlay relationship of lead in granite porphyry molybdenum ore, which will undoubtedly bring certain economic effects to the future production of molybdenum. The ore sample nine Study Party A, a variety of co-grinding test sample as many as about 150, made of microscopic detection system, electron probe made of lead, zinc, titanium, four analysis, X-ray ore Six pieces of diffraction analysis, granite mineralized porphyry molybdenum ore single mineral separation and trace element analysis and related constituent elements determination of a total of nine, ore representative photomicrographs.
