The application discloses a control method of an oxygen-enriched side-blown smelting process, which is suitable for smelting processes of furnace charging materials containing pyrolysis residues and copper sulfide ores in an oxygen-enriched side-blown smelting furnace. At least two operation parameters of oxygen content in flue gas, copper matte phase grade, Fe3O4 content in slag, copper content in slag and slag fluidity are obtained in the smelting process, so as to judge the oxygen potential state in the furnace and the matte-slag separation state; when the oxygen potential in the furnace is increased and accompanied by the increase of the Fe3O4 content in the slag, the oxygen-enriched concentration and / or the side-blown oxygen supply amount are reduced; when the slag fluidity is reduced and / or the copper content in the slag is increased, the flux adding amount is adjusted. Through the linkage adjustment of the oxygen supply parameters and the flux adding amount, the accumulation of Fe3O4 is inhibited, the copper loss with the slag is reduced, and the stable smelting operation is restored.

This invention specifically relates to an ecological remediation method for heavy metal-contaminated soil in copper mine tailings ponds based on a composite amendment—Bacillus subtilis—and *Carex balsamina*, belonging to the field of ecological remediation technology for heavy metal pollution in mining soils. The method includes soil pretreatment, preparation and mixing of the composite amendment, addition of Bacillus subtilis bacterial solution, and planting and maintenance of *Carex balsamina*. The composite amendment, with a specific ratio, rapidly improves the physicochemical properties of the highly acidic and barren tailings soil, creating a suitable habitat for functional microorganisms and resilient plants. Bacillus subtilis activates rhizosphere heavy metals and promotes plant growth, forming a symbiotic and synergistic system with *Carex balsamina*, thereby enriching the soil with heavy metals such as Cu and Cd. This invention significantly increases soil pH, reduces salinity, increases organic matter, and improves the removal rate of Cu and Cd. The method uses readily available raw materials, is simple to operate, and is environmentally friendly, making it suitable for large-scale ecological remediation of heavy metal-contaminated sites such as copper mine tailings ponds.
