前言该铜矿是江西铜基地的重要矿山之一,也是我国少有的高品位铜硫矿床。按空间位置分为南北两个矿带,北矿带为含铜黄铁矿型矿床,南矿带为矽卡岩型矿床,两者均属于广义的中温热液矽卡岩矿床。北矿带矿石是首先开采的对象,为了更好地选择选矿工艺流程和处理方法,对该矿带的矿石性质、工艺特性进行了仔细的研究。北矿带的矿石性质最主要的为含铜黄铁矿约占80％,其次为含铜高岭土约占10％,含铜角砾岩占5％,含铜火成岩、含铜砂岩及其他类型占5％,矿区的围岩蚀变种类有矽卡岩化、矽化、大理岩化、高岭土化、绿泥石化及绿帘石化等。本研究的矿样采自北矿带28米到—40米中段,研究结果可以给该矿石的加工处理指明方向。
Foreword The copper mine is one of the important mines in Jiangxi Copper Base and is also one of the rare high-grade copper and sulfur deposits in China. According to the spatial location, it is divided into two northern and southern ore belts. The northern ore belt is a copper-bearing pyrite type ore deposit, and the south ore belt is a skarn type ore deposit, both of which belong to the generalized mid-temperature hydrothermal skarn deposit. North ore ore mining is the first object of mining, in order to better select the beneficiation process and treatment methods, the ore properties of the mine, the process characteristics of a careful study. The ore quality of the northern ore belt is about 80% of copper-bearing pyrite, followed by copper-bearing kaolin about 10%, copper-bearing breccias accounting for 5%, copper-bearing igneous rocks, copper-bearing sandstones and other types 5%. The types of wall rock alteration in the mining area are skarnization, silicification, marbleization, kaolinization, chloritization and epidermalization. The ore samples from this study are collected from the middle of the northern ore belt of 28 meters to -40 meters and the research results can indicate the direction of the ore processing.
