Embodiment 1
[0049] a. Add water glass to 100kg of ceric rare earth slag to deacidify the ceric rare earth slag to a pH value of 6.8;
[0050] b. Add 25kg of carbon powder and 35kg of alkaline binder to the deacidified ceric rare earth slag, and press it into rare earth pellets;
[0051] c. Put 228kg of silica, 171kg of carbon reducing agent and the above-mentioned rare earth pellets together into the furnace for smelting for 2.5 hours, take them out of the furnace and cast them, and obtain high-cerium rare earth ferrosilicon alloy.
[0052] The composition of the high cerium rare earth ferrosilicon alloy obtained in this embodiment is calculated by mass percentage: RE is 29%, Si is 49.5%, Ca is 0.09%, Al is 0.45%, wherein Ce / RE is 85%, and the rest For Fe.
