Abstract
The invention provides a method for treating electronic waste or copper-nickel sludge -containing waste by means of metallurgical technology. The method comprises the following steps of: performing pretreatment for the waste; evenly mixing and stirring 15%-30% of pretreated waste, 5%-10% of curing agent and copper powder with total copper content of 25%-35% to prepare a 'waste brick', and solidifying and drying the 'waste brick'; and smelting the waste brick in a smelting furnace. In comparison with the prior art, in the method provided by the invention, the harmful wastes containing the copper-nickel sludge, the circuit boards, the connection wires, and the like, are treated simultaneously, the metal resource substances, such as copper, nickel and noble metal, in the material are recycled, the organic ingredients crack and burn, and other ingredients are converted into steady broken glass.
