The initial stage growth mechanism of. LaFeO. 3 perovskite has been investigated using magnetomechanical milling of La 2. O. 3. and Fe. 2. O. 3
A process consisting of ball milling followed by NaOH leaching was developed to selectively dissolve alumina from black dross. From the ball milling treatment it was found that milling speed greatly affected the leaching behavior of silica and the oxides of Ca Fe Mg and Ti present in dross. The leaching behavior of the mechanically activated dross was investigated by varying NaOH
2020-4-27Whereas the ball-milling time Figure 1a and agate ball-to-CuO mass ratio Figure 1b had little eect on RR120 adsorption onto CuO the milling speed Figure 1c showed greater inuences. The highest RR120 adsorption capacities under dierent ball-milling conditions were 65.38 66.54 and 63.56 mg g1at a milling time of 9 h
