【摘要】 黝铜矿的溶解实验研究极为罕见。本文对取自我国云南金满脉状铜矿床中的天然黝铜矿在不同物化条件下的溶解特征进行了研究，初步探讨了Cu、Fe、Zn、As、Sb在中低温热液体系中的地球化学行为及黝铜矿的沉淀机理。结果表明：在酸性条件下，上述组分主要以氯络合物形式迁移，而在碱性条件下，则主要以碳酸的络合物形式迁移；温度的下降以及pH的降低或升高是导致本区黝铜矿大量沉淀的主要因素。更多还原

【Abstract】 Little work has been done on the dissolution experiment of tetrahedrite both at home and abroad. This paper deals with the dissolution features of natural tetrahedrite collected from the Jinman vein copper deposit, Yunnan Province, China under different physical and chemical conditions. On this basis, the geochemical behaviour of Cu, Fe, Zn, As and Sb in the moderate-low temperature hydrotkermal system and the precipitation mechanism of tetrahedrite are preliminarily discussed. The results show that the above-mentioned elements transported mainly in the form of Cl complex under acidic condition and of carbonic acid complex under alkaline condition. The decrease of temperature and the fluctuation of pH are the main factors leading to the extensive precipitation of tetrahedrite in this area studies.更多还原
