Information

  Beijing Golden Great Wall Machinery Manufacturing Plant won the bid for China National Gold Group Jilin Guangshun Mining Co., Ltd. Songjianghe gold mine desorption point desorption and carbon regeneration project.

  This project is located in Songjianghe Village, Dapuchaihe Town, Dunhua City, with a mining area of 3.16㎞². The mining area is located in the northwestern part of the Changbai Mountains. The terrain elevation is generally 600-700m, and the relative elevation difference is 200-300m. It is a low mountain landform area.

  Design underground mining, adopt comprehensive mining method, comprehensive mining method, shallow hole mining method and segmented open field mining method. The comprehensive mining loss rate of the whole mine is 13%, and the ore dilution rate is 18%. Flat tunnel + blind shaft development, single-wing diagonal ventilation. The main process indicators are the selected grade of the raw ore: 2.61 g/ton; the total gold recovery rate is 89.78%; the tailing grade is 0.33 g/ton. The tailings discharge method adopts dry storage after filtration, and the bottom of the storage is fully impervious.
