摘要
试验采用造锍熔炼工艺流程综合回收处理黄钠铁矾渣,在温度1 250℃,时间2 h,还原剂碳与炉料质量比10%,黄铁矿与铁矾渣量比22%,石英石与铁矾渣量比20%,石灰石与铁矾渣量比0.5%的条件下,铜、镍等有价金属能较好的富集在镍锍中。通过造锍熔炼试验表明:采用造锍熔炼工艺综合回收处理黄钠铁矾渣,镍直收率可达到90%以上,铜直收率可达到91%以上。
The iron vitriol dreg of yellow sodium is comprehensivly recoveried by matte smelting process flow in the test, when the temperature is 1250℃, the time is 2 hours, the mass ratio of reducing agent carbon with the furnace charge is 10%, The mass ratio of pyrite with ferrovanadium slag is 22%, the ratio of quartz stone with ferrovanadium slag is 20% ; in condition of the mass ratio between the lime stone and ferrovanadium slag is 0. 5%, the valuable metals, such as copper, nickel and so on can be enriched better in nickel matte. The test of matte smelting show： the iron vitriol dreg of yellow sodium can be comprehensivly recovered by matte smelting process, the direct recovery rate of nickel can reach to more than 90%, the direct recovery rate of copper can reach to more than 91%.
