Anode for electrolyzing rare earth metal and alloy molten salt as well as preparation method and application of anode
The invention discloses a rare earth metal and alloy molten salt electrolysis anode and a preparation method and application thereof, and the rare earth metal and alloy molten salt electrolysis anode comprises the following components based on the total weight of the anode: 20-40 wt% of anode scrap powder, 3-5 wt% of petroleum coke, 20-25 wt% of asphalt, and the balance of graphite powder; the anode scrap powder is prepared through the following steps that the 2-5 mm surface layer of a waste anode used after rare earth metal and alloy electrolysis is scraped off, and an anode scrap with the surface layer removed is obtained; and crushing the anode scrap without the surface layer, and then performing grading treatment to obtain anode scrap powder, namely the anode scrap powder. The anode scrap powder obtained from the waste anode can be used as one of the raw materials to obtain the anode for electrolysis of the rare earth metal and the alloy molten salt, so that the resource utilization rate can be improved.
本发明公开了一种稀土金属及合金熔盐电解用阳极及其制备方法和应用，所述稀土金属及合金熔盐电解用阳极包括如下组分：基于阳极的总重量，残极粉为20～40wt％，石油焦为3～5wt％，沥青为20～25wt％，余量为石墨粉；其中，所述残极粉由包括以下的步骤制备而得：将稀土金属及合金电解使用后的废阳极的2～5mm的表层刮去，得到去表层的残极；将去表层的残极进行粉碎，然后进行分级处理，得到残极粉末，即为残极粉。本发明可以采用废阳极获得的残极粉作为原料之一以获得稀土金属及合金熔盐电解用阳极，这样可以提高资源利用率。
