福建连城锰矿淋滤型贫氧化锰矿选矿试验,1978年由江苏冶金研究所完成小型试验后,1979～1980年又对该矿进行80吨矿样的扩大试验。1982年经冶金部批准建设,1985年12月建成,1986年7月完成生产调试并投产使用。1987年5月该流程通过部级鉴定。 1.原矿性质考查福建连城锰矿属风化壳型的锰矿床,矿体赋存于第四纪黄土层、红土层及砂质粘土层中,以成因类型来划分有坡积型及淋滤型两种,以淋滤型为主。该矿含锰主要矿物有硬锰矿、软锰矿和锰土;脉石主要为石英、高岭土、绢云母、蛋白石、石髓、褐铁矿
Fujian Liancheng manganese leaching lean manganese ore beneficiation test, in 1978 by the Jiangsu Institute of Metallurgy to complete a small test, 1979 to 1980 and the mine again 80 tons of ore expansion test. Construction approved by the Ministry of Metallurgy in 1982, completed in December 1985, commissioned and commissioned in July 1986. May 1987 The process passed the ministerial level appraisal. 1.Organic properties of Fujian Liancheng Manganese Mine is a weathering crust manganese deposits, ore bodies occur in the Quaternary loess layer, red soil layer and sandy clay layer, the type of formation to the slope type and leaching type two Species to leaching-based. The mine’s main manganese-bearing minerals are hard manganese, pyrolusite and manganese; gangue mainly quartz, kaolin, sericite, opal, stone pulp, limonite
