The invention discloses a method for treating valuable secondary materials such as
electronic waste through an
oxygen inclined blowing
rotary converter. The method comprises the following steps: (1) material preparation: pretreating valuable secondary materials such as electronic wastes; (2) burdening: burdening the following components in percentage by
mass: 62-92% of valuable secondary materials such as electronic wastes, 5-20% of
scrap iron or iron shots, 2-10% of
quartz stone or
silicon powder and 1-8% of limestone; (3)
smelting and deslagging: continuously adding materials,
smelting under an
oxygen-enriched condition, pouring out
slag when the quantity of melt in the furnace is close to the position of a furnace mouth, continuously feeding and
smelting, and repeating the operation for multiple times until crude
copper liquid in the furnace is close to the furnace mouth; (4) blowing: blowing industrial
oxygen or oxygen-enriched air into the furnace, blowing for 30-120 minutes, sampling and observing, and finishing blowing after conditions are met; and (5) discharging: pouring out the crude
copper liquid through a furnace mouth,
casting the crude
copper liquid into an
ingot shape, and leaving furnace
slag in the furnace to enter the next operation furnace period. The method is efficient, energy-saving, environment-friendly, high in
recovery rate and high in
raw material adaptability.
