| 摘 要： | 东海金矿床位于甘肃北山重要的Au,Ag多金属成矿带上,为一含伴生Ag的多金属金矿床.具长期活动特征的花牛山-察客尔呼都格压扭性断裂横贯成矿带,成矿的有利位置为大断裂及次一级断层、层间裂隙,断裂控矿十分明显.主要矿石类型为破碎蚀变岩型(据氧化程度不同,又分为氧化矿和原生矿)、石英脉型.目前黄金生产只对氧化矿采用堆浸法提金,贵液吸附工艺由原来的活性炭吸附法,改用锌粉置换沉淀法后,使贵液中的Au和Ag得到了充分的回收利用,对原生矿的开发利用则需要进一步的研究.

| Abstract: | The Donghai gold deposit locates in Beishan AuAg-polymetallic mineralization belt of Gansu,it is a polymetallic deposit associated with Ag.In long-active Huaniushan-Chakeerhuduge compressive shear fault crossed the mineralization belt,the favorable position of mineralization is at the major rupture in the first class,secondary class fault and the crack among layer.It is very obvious that the fault control the rupture zone and the ore-forming.Main ore is broken alteration rock type(according to different oxidation degree,it divided into oxidation and primary ore type) and quartz vein type.At present gold products only make out of heap leaching method from the oxidation ore type.The valuable liquid absorption technology that replaced the original activated charcoal adsorption method by the zinc powder exchange precipitation has been successful.It makes Au and Ag of valuable liquid to full extraction and utilize.But it is need of further studying the development and utilization for primary ore type. |
