The experimental procedures and results obtained in the study on the preparation of mischmetal rich in lanthanum with fusion electrolysis using the regressive-orthogonal method are presented. The equation for current efficiency obtained is as: y = 0. 4754-0. 0118x_1 + 0. 05323x_2-1. 901 × 10￣(-3) x_3 + 0. 1099x_4 + 0. 01526x_1x_2 + 5. 319 ×10￣(-3)x_1x_3-0. 01433x_1x_4 -0. 02897x_2x_3 + 9. 356 × 10￣(-3)x_2x_4+ 0. 02037x_3x_4-. The equation is in good agreement with the experimental data with high reliability proved hy significance and reliability tests,thus may be used for predicting and controlling the process. The results showed that the regressiveerthogonal method made the experimentation simpler and the analyzing of the experimental data and optimization easier, and also povided with high experimental accuracy.
