1966年初,向山硫铁矿与化工矿山研究院合作,在解决向山硫铁矿选矿厂尾矿坝酸性回水的应用取得突破。为后期开展酸性水闭路循环使用提供了条件。迄今,加石灰(呈碱性)浮选硫铁矿物在生产上应用已有十几年。对低品位硫铁矿石浮选加石灰,解决了尾矿坝排放酸性水对环境的污染,设备的腐蚀问题,提高了硫精矿回收率。(一)矿石性质、水质及存在问题矿区岩石主要为白垩纪(中)酸性火山岩。矿石类型复杂,黄铁矿矿石于围岩蚀变带中。围岩蚀变以绢云母化、矽化、绿泥石化为主,高岭土化次之。黄铁矿呈细粒浸染或
In early 1966, the cooperation of Xiangshan Pyrite Mine and Chemical Mining Research Institute made a breakthrough in solving the application of acid backwater to the tailing dam of Shan Pyrite Concentrator. For the latter to carry out closed loop acidic water provided the conditions. So far, the application of lime (alkaline) flotation of pyrite has been in production for more than ten years. Flotation of low grade pyrite flotation of lime, to solve the tailings dam emissions of acidic water pollution of the environment, equipment corrosion problems and improve the sulfur concentrate recovery. (A) the nature of ore, water quality and problems Mining rock is mainly Cretaceous (middle) acidic volcanic rocks. The ore type is complex, pyrite ore in the wall rock alteration zone. Wall rock alteration to sericitization, silicification, chloritization-based, followed by kaolin. Pyrite was finely disseminated or
