In this paper,the results of semi-commercial experiment ofbacteria he ap leaching Shannan low-grade ore in Fuzhou Uranium Mine are summarized. Heap s ituation, spraying and sprinkling devices, continuous oxidizing equipment of bio membrane and technological process are briefly introduced. During 158 d of bacte ria leaching experiment, 1 142.14 kg uranium has been recovered. The leachi n g rate is 69.45％ and 66％ respectively by liquid and tailing measurement. The a cid consumption is 2.11％, and the total liquid/solid is 2.55 L/kg. It suppl ies an economic and feasible technical way to recover uranium from low-grade uraniu m ores.
