METHOD FOR SEPARATING METAL FROM A DIFFICULT DISSOLUBILITY WASTE METAL/POLYMER

摘要

PURPOSE: A method for separating metal from a non-dissoluble waste metal-polymer composite is provided to reduce the amount of electricity used by carbonizing the metal-polymer composite. CONSTITUTION: A method for separating metal from a non-dissoluble waste metal-polymer composite comprises: a pretreatment step (S10) of putting non-dissoluble waste metal-polymer composite waste in an induction furnace; an induction heating step (S20) of thermally decomposing a polymer coated on a metal material and inducing carbonization by directly heating the metal material; a crushing step (S30) of separating the carbonized polymer from the metal material and crushing the carbonized polymer; and a collection step (S40) of collecting high purity metal materials.
