| 摘 要： | 云南省维西大宝山铜矿区位于青藏高原东南缘,西南三江铜、铅锌、金、银等多金属成矿带中,是受构造控制形成的典型热液矿床。文章对矿区内矿体地质特征进行概述,在此基础上对铜矿石体重与品位的关系进行探讨。利用涂蜡测得矿区内62件样品的体重,对不同矿石类型的体重进行分析整理。研究表明:同品位铜硫化矿体重大于同品位铜氧化矿体重;在铜氧化矿中,体重与品位呈负相关,在铜硫化矿中,体重与品位呈正相关。

| Abstract: | The Dabaoshan copper deposit, located in Weixi county, Yunnan Province, occurs in the southwestern Sanjiang metallogenic belt of copper, zinc, gold and silver deposits, southeastern margin of Qinghai-Tibetan Plateau. It is a typical hydrothermal deposit which is controlled by structures. On the basis of describing geological characteristics of ore bodies, the relationship between the ore weight and ore grade was discussed. The weight of 62 samples collected in the deposit area was measured by using wax method, and the weight of different types of ore was analyzed and sorted. The result shows that the weight of oxidized copper ore is less than that of the sulfide copper ore in the same grade. In the sulfide copper ore, there is a positively correlation between the ore weight and ore grade but negatively correlated in the oxidized copper ore. |
