我矿采用一段离析法处理含Cu2％左右的高硅铁质难选氧化矿,经回转窑离析和浮选,得到含Cu25％±、C10％±的离析铜精矿;配入石灰石熔剂,再经反射炉(90米~2)熔炼直接得到含Cu92～95％、Fe3～6％的粗铜和含Cu0.6％的炉渣。几年的生产实践表明,采用反射炉熔炼离析铜精矿,工艺简单,技术可行;同时也存在着燃料消耗大(22～25％),床能力低(1.8～2.1吨千精矿/米~2·日)等缺点。特别是在生产过程中,炉床易产生炉结,影响正常生产的进行。因
I mine using a segregation process containing about 2% of Cu-containing high-iron refractory oxide, after kiln separation and flotation, containing Cu25% ±, C10% ± isolated copper concentrate; with limestone flux, and then Refining furnace (90 m ~ 2) smelting direct access to containing Cu 92 ~ 95%, Fe3 ~ 6% of the blister copper and Cu0.6% of the slag. Years of production practice shows that the use of reflective furnace smelting isolated copper concentrate, the process is simple, technically feasible; there are also fuel consumption (22 ~ 25%), low bed capacity (1.8 ~ 2.1 tons of fine concentrate / 2 · day) and other shortcomings. Especially in the production process, easy to produce hearth furnace knot, affecting the normal production. because
