- Abstract
Sedimentary bauxite is lhe main type of the deposits in China. The reserve-produclion ratio has gradually declined wit) decades of development, thus green exploitation of diffTcult-to-use resources in the deep is a matter of great urgency. Through static leaching test and electrode heating simulation combined with the successful experience of in-situ leaching technology in uranium and rare earth mining, the application conditions of the technology in solid mineral mining ae summarized as follows: I) soluble mineral2)stable orebody distribution, 3)roof and floor conditions and 4)orebody permeability. The bauxite resources in North China fit in well with the above conditions and are suitable for in-situ leaching technology. TVie technological scheme for in-situ leaching mining of sedimentary bauxite is also proposed, which provides idea for pilot test design in the next step.
