Abstract:
    The invention relates to a post-type tungsten selecting method, wherein it uses two cyclone-static foam float selecting posts as selecting devices, with three slurry barrels, liquid level controller and mine circulator. It first feeds the mine into slurry barrel, adds float select agent to mix the slurry; feeds the slurry via feeding pump to the rough float selecting post to be separated and selected; then the rough selected and fine selected mines flow into the fine selecting float selecting post, and the rough selected mine is discharge at the bottom of rough selecting float selecting post, to be selected in the fine selecting post; and the fine selected mine is discharged at the upper fine mine outlet, and the tail mine is discharge at the bottom outlet into mine buffer pool, to be fed back to the slurry barrel. The invention has low cost and high efficiency.
