   Or, after the iron content slag of the Iron containing silicate minerals phase and/or the Fe-riched phase is poured into attemperator, use is following Method is separated：The modified magnetic separation separation of slag：Slag into attemperator, it is 0~1200 DEG C to be blown into preheating temperature Oxidizing gas, and ensure slag temperature>1250 DEG C, complete the conversion of magnetic iron ore in slag；By the slag slow cooling after oxidation extremely Room temperature, crush, magnetic separation, product is magnetite concentrate and mine tailing, and mine tailing is as construction material；

   Method G：The iron content slag fused reduction iron-smelting of the Iron containing silicate minerals phase and/or the Fe-riched phase, including it is as follows Step：

   G-1, the iron content slag of the Iron containing silicate minerals phase and/or the Fe-riched phase is retained in melting reaction device or Slag is poured into attemperator, ferrous material, reducing agent are added into iron content slag, carries out melting and reducing, in real time monitoring reaction Slag, meet following condition simultaneously by regulation and control：The temperature for reacting slag is 1350~1670 DEG C and the basicity of reaction slag CaO/SiO₂Ratio=0.6~2.4, the slag after the completion of being reacted；

   G-2, the oxidizing gas into slag after blowing preheated carry out melting and reducing, the slag formed after reduction, wherein：Oxidation Property gas preheating temperature be 0~1200 DEG C, and during injection, meet following condition simultaneously by regulation and control：Reaction is completed The temperature of slag afterwards is 1350~1670 DEG C of DEG C of basicity CaO/SiO with the slag after the completion of reaction₂Ratio=0.6~2.4；

   G-3, separated and recovered using one kind in following two methods：

   Method I：Mixing slag after reduction is poured into insulation slag ladle, is slowly cooled to room temperature, obtains slow cooling slag；Metallic iron settles To the bottom of reaction unit, form iron and stick together；By containing metal iron layer in remaining slow cooling slag, 20~400 μm of granularity is crushed to, ore grinding, Residual metallic iron and mine tailing are isolated in magnetic separation；

   Method II：Mixing slag after reduction, cooling-sedimentation, slag-gold separation, obtain molten iron and the slag after reduction；After reduction Slag, according to the one or more in A~E, carry out slag treatment；Molten iron is sent to converter or electric furnace steel making；

   Or, containing the Fe-riched phase water quenching or air cooling or pour into attemperator slow cooling or acquisition is combined with gravity treatment through manual sorting, Copper raw material or magnetic separation separation are carried as blast furnace ironmaking raw material or direct reduction iron making raw material or iron making by smelting reduction iron material or flotation As copper metallurgy or the raw material of direct reduction iron making after metallic iron；In floatation process, float product is containing copper concentrate and iron ore concentrate, copper Concentrate returns to copper metallurgy system, and iron ore concentrate is as blast furnace ironmaking raw material or direct reduction iron making raw material or iron making by smelting reduction iron material； Wherein, in Direct Reduction, after reduzate magnetic separation separation, metallic iron and mine tailing are obtained, mine tailing returns to copper metallurgy system；

   The Direct Reduction is using the conduct of any of rotary hearth furnace, tunnel cave, car-bottom furnace, shaft furnace, rotary kiln, induction furnace Reduction apparatus, using gas base or coal base reduction technology, gas base is natural gas and/or coal gas, coal base be anthracite, bituminous coal, lignite, One or more in coking coal, coke powder, coke, reduction temperature are 900~1400 DEG C, basicity CaO/SiO₂Ratio=0.8~ 1.5。
