重庆城口锰矿是中国西南地区的大型碳酸盐型锰矿床(蔡怀智,1990),其位于大巴山深大断裂南侧,扬子准地台北缘的巨大四陷带内(万平益,2000)。该矿主要由三矿区组成,分别为城口县西部的高燕锰矿区、东部的大渡溪锰矿区和修齐锰矿区。高燕矿区矿石品位低,矿物组成复杂,资源利用率低,为典型高磷贫锰矿石。本文通过对高燕矿区矿石工艺特征进行研究,以期对后期选矿及矿石综合利用途径研究提供良好的参考依据,提高资源利用率。
Chongqing Chengkou Manganese Mine is a large carbonate-type manganese deposit in southwestern China (Cai Huai-zhi, 1990). It is located in the huge four-member zone to the north of the Yangtze Platform in the south of Dabashan Deep Large Fault (Wanpingyi, 2000). The mine is mainly composed of three mines, namely the Gao Yan Manganese mine in the west of Chengkou County, the Dadu River manganese mine and the Xiuqi Manganese mine in the east. High Yan ore ore grade is low, complex mineral composition, low utilization of resources, as a typical high phosphorus poor manganese ore. In this paper, the characteristics of ore technology in Gaoyan mining area are studied in order to provide a good reference for the study of the post-processing beneficiation and the comprehensive utilization of ore to improve the resource utilization rate.
