J. Cent. South Univ. (2020) 27: 772-779 DOI: https://doi.org/10.1007/s11771-020-4330-1 Effect of oxalate on seed precipitation of gibbsite from sodium aluminate solution YU Hai-yan(于海燕)1, 2, ZHANG... performance and kinetics of gibbsite from sodium aluminate solution with different sodium oxalate concentrations as well as the corresponding influence mechanism of oxalate during the seed precipitation......
sulfate solution with sodium persulfate. The effect parameters of stirring speed, temperature, particle size, concentrations of ammonia, ammonium sulfate and sodium persulfate were determined. The results show that the leaching rate is nearly independent of agitation above 300 r/min and increases with the increase of temperature, concentrations of ammonia, ammonium sulfate and sodium persulfate......
