Example 1:
Take hydrolysis residue (main content: Zn is 14.44%; S is 13.03%; Pb is 0.39%; Ag is 30.7g / t; Cu is 0.3%; Fe is 14.93%; CaO is 13.88%) 900kg, and dry it with hot air After drying, the water content of the hydrolyzed slag after drying is 10%, and then it is pressed in the brick making machine to obtain the hydrolyzed slag lump ore, which is naturally dried in a ventilated place for 13 hours and then enters the batching process section. Take zinc kiln slag (main content: CuO is 1.12%, TFe is 31.36%, Zn is 8.15%, Ag is 119.3g / t, In is 198.4g / t) 63% of materials, the initial particle size requirements of zinc kiln slag+ 10 mesh accounted for 85%; 13% of coke with a fixed carbon content of 74%, 4% of quartz stone with a SiO2 content of 98% or more, 14.5% of hydrolyzed slag ore, and 5.5% of pyrite were added. The five materials are naturally mixed and then smelted in the blast furnace. The process conditions controlled by the blast furnace are: the blast furnace smelting...

Take zinc kiln slag (main content: CuO is 1.12%, TFe is 31.36%, Zn is 8.15%, Ag is 119.3g / t, In is 198.4g / t) 71% of materials, the initial particle size requirements of zinc kiln slag+ 10 meshes account for 90%; 13% coke with a fixed carbon content of 74%, 3% quartz stone with a SiO2 content of 98% or more, 9% hydrolyzed slag lump ore, and 4% pyrite are added. The five materials are naturally mixed and then smelted in the blast furnace. The process conditions controlled by the blast furnace are: the blast furnace smelting temperature distr...
