The invention provides a comprehensive treatment method for waste
refractory materials in the ternary
anode material preparation process. The waste
refractory material comprises
silicon, aluminum andmagnesium impurities, and the method comprises the following steps that 1) the waste
refractory material, the acid and the additive are mixed, leaching reaction and then
separation process are carriedout to obtain a purified refractory material and a
leachate; 2), the pH value of the
leachate is adjusted to be 2-4, and
solid-liquid separation is carried out to obtain
solid slag and a separation solution; 3) the pH value of the separation liquid is adjusted to be 4.5-5.5, and
solid-liquid separation is carried out to obtain solid
slag and an aluminum removal solution; 4) the pH value of the aluminum removal solution is adjusted to be more than or equal to 9, and solid-liquid separation is carried out to obtain a ternary mixture and a co-
precipitation separation solution; 5)
magnesium is removed, specifically, the pH value of the co-
precipitation separation solution is adjusted to be more than or equal to 11, and solid-liquid separation is carried out to obtain solid
slag and a
magnesium removal solution; and 6)
lithium is precipitated, specifically, a precipitant is added into the
magnesium removal solution, and solid-liquid separation is carried out to obtain a
lithium-containingsubstance and a
lithium precipitation solution. According to the method, recycling of
nickel,
cobalt,
manganese and lithium in the waste refractory material is realized, the waste refractory materialis purified, and the industrial production is facilitated.
