【摘要】 <正>大厂是我国著名的锡石-硫化物多金属矿田。其中最具代表性的锡石-硫化物矿床集中在长坡矿区(包括铜坑)。它是以锡为主,可综合利用锌、铅、锑、银、铟、镉、砷、硫等多种元素的巨型硫化物矿床。矿石成分复杂,矿物种类繁多,除锡石及大量常见的铁闪锌矿、黄铁矿、磁黄铁矿、毒砂外,还发现有自然锑、自然铋等金属矿物。特别是硫盐矿物种类之多,富集程度之高,实属世界罕见。近年来,李锡林等对该区硫盐类矿物有过多更多还原

【Abstract】 The Changpo deposit is the largest and the best representative deposit in the well-known Dachang cassiterite-sulfide polymetallic ore field,Zhuang Autonomous Region of Guangxi.In this cassiterite-sulfide deposit tin is the major metallic element and a variety of other metals such as zinc,lead,antimony, silver,indium and cadmium can be integratedly recovered.In studying the mineralization mechanism of this ore field,the authors conducted rather systematic researches on the ore compositions of the Changpo deposit, especially on the sulfosalt minerals.The purpose was to explore the physical -chemical conditions for ore formation and to find out the mode of occurrence of some useful elements for the integrated utilization of the ore.The study suggests that,in addition to cassiterite and a great quantity of such common sulfide minerals as iron-,zinc-,and arsenic-bearing ones,the deposit is obviously characterized by the presence of large amounts of sulfosalt minerals.Parts of the results of the research on the sulfosalt minerals with emphasis on the Changpo deposit are summarized briefly as follows.更多还原
