Geological characteristics, types and development and utilization value of Shuitou fluorite deposit in Linxi, Inner Mongolia

This paper is the result of mineral exploration engineering.

Objective The geological characteristics, genesis and deposit types of Shuitou fluorite deposit are systematically studied to fully and rationally develop and utilize its resources.

Methods Based on the analysis of the geological characteristics, ore genesis and current situation of ore development-utilization, we summarized ore types and development-utilization value of Shuitou fluorite deposit.

Results Shuitou large fluorite deposit was formed in the early Cretaceous, which ore bodies mainly existed in the upper Permain Linxi Formation tuffaceous siltstone. It's a fault-control, medium-low-temperature hydrothermal, fracture-filling type deposit. The reserve resources/reserves of fluorite ores are 1700.48 kt, with a CaF₂ average grade 62.27% and CaF₂ mineral content of 1058864 t. The spectral analysis shows that useful component is CaF₂, and the ore has good floatability and belongs to the easy separation ore. Fluorite concentrate with CaF₂ grade 97.56% and recovery rate 87.07% can be obtained by one state rougher, two states scavenger and four states cleaner.

Conclusions The comprehensive analysis indicate that Shuitou large fluorite deposit has good development-utilization value.
