[en] In recent years, the rapid development of nuclear power has given rise to an urgent demand for uranium products which enhances the innovation and development of uranium mining and metallurgy in China. This paper introduces the progress of in-situ leaching uranium in China. After the success of the first in-situ leaching uranium test in 1985, China have conducted extensive research on uranium in-situ leaching of the sandstone type deposits in Xinjiang Uygur and Inner Mongolia autonomous regions. And technologies such as evaluation of sandstone type uranium resources for in-situ leach, well structure and drilling completion, ore underground leaching, control of leaching range, pregnant solution processing and automatic control, have been developed. This paper focuses on the innovative achievements of groundwater seepage field alteration, multilayer ore horizon coordinated and efficient leach, complex orebody leach, leaching solution processing of distributed and small ore blocks, and digitized uranium deposits, according to the complex sandstone uranium deposits in geology, hydrogeology and ore characteristics. Based on the characteristics of the sandstone type uranium deposit and the existing uranium in-situ leaching technology, the developing direction of uranium leaching in China is proposed.
