| titleOfInvention | Oxygen-enriched side-blown smelting method for lean high-silicon copper concentrate |
| abstract | The invention relates to an oxygen-enriched side-blown smelting method for lean high-silicon copper concentrate, which comprises the following steps: taking 10-64% of lean impurity high-silicon low-copper concentrate and less than or equal to 44% of lean impurity high-silicon low-copper concentrate, adding 29-42% of copper-rich high-sulfur ore and 4-10% of slag concentrate into the concentrate,evenly mixing to obtain composite ore, adding 2.15-4.5 percent of CaO into the composite ore, adding into a side-blown furnace, adding fuel with the mass of 3.6-6.8 percent of that of the composite ore, smelting at 1250-1290 ℃, continuously blowing oxygen-enriched air with the concentration of 72-84 percent into the side-blown furnace during the smelting process, wherein the blowing flow is 17000-23000Nm 3 And h, obtaining the matte liquid and the copper smelting slag. The method fully solves the problems of insufficient supply and quality of domestic copper concentrate, realizes the breakthrough of zero flux rate by taking the high-silicon ore as a material mixing framework and combining the measures of optimizing the opposite side blowing smelting slag type, improving the oxygen-enriched concentration, improving the bed capacity and the like by adjusting the proportion, and integrates the optimization of the matte grade and the slag copper-containing data. |
