金,虽能形成独立矿床,但从目前国内外黄金生产的情况来看,约有30～50%来自多金属硫化矿床的综合回收.由于过去对伴生金研究得不够,各厂矿一般多在粗铜电解时顺便回收,迄未形成一套成熟的硫化矿床伴生金的研究方法.各选冶厂条件不同,金的回收率也有很大差异.为了提高黄金的回收率,加强伴生金的形成条件、赋存状态、分布规律及其工艺性质的研究,就有着重要的意义.近年来,我们共同对铜陵地区的几个夕卡岩型硫化矿床中的伴生金进行了一些研究,为了交流情况,推动矿床综合利用工作,现将我们的研究方法初步总结如下,不当之处,请批评指正.
Although gold can form an independent deposit, about 30% to 50% of the gold recovered from polymetallic sulphide ore deposits is not enough in the past due to the current situation of gold production both at home and abroad. However, Copper electrolysis by the way of recovery, has not yet formed a mature sulfide mineralization associated gold research methods of the various conditions of the metallurgical plant, the recovery rate of gold are also very different.In order to improve the recovery rate of gold to strengthen the formation of associated gold conditions , The state of occurrence, the distribution law and the nature of its technology, it is of great significance.In recent years, we have carried out some researches on the associated gold in several skarn-type sulfide ores in Tongling area. In order to exchange information, To promote the comprehensive utilization of the deposit, the initial summary of our research methods are as follows, inappropriate, please comment on criticism.
