The invention belongs to the technical field of
rare earth element separation, and particularly relates to a
fluidization, separation and enrichment method for
rare earth element carrier ore of mine
solid waste. Comprising the following steps that a mixture of pulverized
coal and
ferrosilicon powder serves as a separation medium and is added into a vibration gas-
solid separation
fluidized bed device, and the vibration frequency, the amplitude parameter and the gas speed of pulse
airflow of the vibration gas-
solid separation
fluidized bed device are set according to the density of mine solid waste
rare earth element carrier minerals, the separation
granularity and the content of rare earth elements; the mine solid waste
rare earth element carrier minerals form a scattered
fluidization environment with uniform and stable density under the vibration-
airflow synergistic effect of the vibration gas-solid separation
fluidized bed,
density gradient layering is carried out, and separation and pre-enrichment of rare earth elements in the mine solid waste
rare earth element carrier minerals are achieved. According to the method, high-density
coal gangue containing high rare earth elements is efficiently and accurately sorted, and the problem of pre-enrichment of the rare earth elements in mine solid waste
rare earth element carrier minerals is effectively solved.
