COMPREHENSIVE PROCESSING METHOD AND COMPREHENSIVE PROCESSING SYSTEM FOR COPPER-CONTAINING SLUDGE AND CIRCUIT BOARDS

WIPO Patent Application WO/2019/214507

A1

A comprehensive processing method and comprehensive processing system for copper-containing sludge and circuit boards, the comprehensive processing method comprising: mixing and granulating copper-containing sludge and waste-activated carbon to obtain copper-containing sludge particles; performing side blowing smelting on the copper-containing sludge particles and a circuit board. The waste-activated carbon is used as a reducing agent and a partial combustion agent, which is mixed and granulated with the copper-containing sludge and then side blowing smelted with the circuit board; in addition, a waste mineral oil is used as a supplementary fuel, thereby further reducing the energy consumption costs of side blowing smelting; during the process of side blowing smelting, organic matter of the circuit board burns to generate heat, and the organic matter may be used as a fuel for side blowing smelting, thereby completing the separation of copper and other impurities from the copper-containing sludge and the circuit board, fully utilizing the heat energy of the organic matter in the circuit board, and further reducing the energy consumption costs of side blowing smelting.
