Abstract:
    The invention relates to a bloodstone post-type shortened reverse-flotation selecting method and relative device, wherein it has two systems arranged from high to low, while each one is formed by cyclone-static micro foam selecting post, slurry mixing cylinder, buffer pool, and concentrate magnetic selector; it adds material mine and flotation drug into slurry mixing cylinder to be mixed; adds the material into rough flotation post; the bottom of rough flotation post discharges the qualified bloodstone finished ore product, and the upper foam at the rough floatation post via foam absorber is absorbed into the scavenger floatation post to be scavenged; and the bottom of said scavenger floatation post discharges ore into buffer pool, while its upper foam is the final debris product; the middle ore of buffer pool, via middle ore pump is transmitted to the concentrate magnetic selector to be selected, and the finished ore will be fed back to the mixing cylinder, to be mixed with material and selected again. The invention has simple process and low cost.
