Hebei Fanshan Phosphate Co., Ltd. 

Scale: 1.2 million t/a

Mining method:change caving method to filling 

Because the existence of high-pressure aquifers in the overlying rock layer of the ore body greatly restricts the mine's efficient and stable production, our company innovatively proposed the "roof pre-control, partition isolation, and immediate filling" water prevention and control plan, and adopt the mining technology of “segmented rock drilling, mining in stages, and filling afterwards”. 

Mining Technology:Five-stage phosphorous flotation, three-stage ferromagnetic separation, re-election-strong magnetic separation, two-stage titanium separation.
