Tikanga waihanga
1. Whakarewahia te waikura lanthanum i roto i te waikawa pūhaumāota mā te tikanga matū ka waimeha ki te 100-150g/L (kua tātaihia hei La2O3).Whakawerahia te wairewa ki te 70-80 ℃, ka tohe ki te 48% waikawa pūhāwai.Ka horoia te rerenga, ka tātarihia, ka whakamarokehia, ka kuru, ka whakamarokehia te wai kia whiwhi ai i te lanthanum fluoride.
2. Whakanohoia te wairewa LaCl3 kei roto te waikawa puota ki roto i te rihi konukawata, ka tapirihia te 40% waikawa puowai.Ringihia te wai taikaha ka whakaeto i te toenga kia maroke.
