[0205] Example 1
[0206] A method for recovering valuable components from mixed slag containing copper and iron, including the following steps:
[0207] Step 1. Slag mixing: Add the copper-containing smelting slag of the Osmelt furnace obtained from the slag outlet of the matte smelting furnace and the copper-containing blowing slag (converter slag) obtained from the slag outlet of the converter into the DC electric arc furnace, and at the same time add the cold state Blast furnace slag, VOD / VAD slag and ferroalloy slag produced by smelting carbon ferromanganese, liquid high-lead slag reduction furnace lead smelting slag to form mixed slag; the mixed slag is heated to a molten state to form copper and iron The reaction slag is electromagnetically stirred to achieve natural mixing; the reaction slag is monitored in real time, and the two parameters (a) and (b) are ensured through adjustment and control to obtain the slag after the reaction is completed; corresponding to (a): The t...

[0211] A method for recovering valuable components from mixed slag containing copper and iron, including the following steps:
[0212] Step 1, slag mixing: add the copper-containing smelting slag of the Isa furnace obtained from the slag outlet of the matte-making smelting furnace and the copper-containing blowing slag (converter slag) obtained from the slag outlet of the converter into the pourable smelting reaction slag, and at the same time Add the ferroalloy slag produced from the molten ferrochrome smelting obtained from the slag outlet to form a mixed slag; use oxygen-enriched air, inject natural gas, 20mm anthracite and coke particles, and heat the mixed slag to a molten state to form a mixed slag. The reaction slag of copper and iron, and the reaction slag is electromagnetically stirred to achieve mixing; the reaction slag is monitored in real time, and the two parameters (a) and (b) are ensured through adjustment and control to obtain the slag after the ...
