  • Kinetics of weathered-crust elution-deposited rare-earth ore in a leaching process = Kinetika postopka luženja elucijsko nanesene preperele skorje rude redkih zemelj
    Zhang, L. ...
    The leaching reaction kinetics of weathered-crust, elution-deposited rare earth with mixed ammonium salts was studied. The influence of the concentration of the reagents and the particle size of the ... ore on the leaching rate was investigated. The results showed that the diffusion process and the leaching rate could be improved by increasing the reagent concentration and decreasing the leaching flowing rate and particle size. The leaching process could be explained using the shrinking-core model, which could be controlled with the diffusion rate of the reacting reagents in a porous solid layer. The leaching rate followed the equation 1-2/3[eta] - (1 - [eta][sup]{2/3} = 7.126 x 10[sup]{-4}C[sup]{0.3038}R[sup]{0.1942}t.
