摘要
采用X -射线衍射、电子探针等多种手段 ,研究烟化法锑氧粉的化学成分、物相组成等特性 ,进行烟化法锑氧粉还原正交试验。结果表明 ,烟化法锑氧粉与鼓风炉锑氧粉相比 ,成分复杂 ,杂质含量高 ,其中Sb2 O3 以等轴晶系为主 ,少量为斜方晶系 ,杂质相为无定型炭和石墨、赤铁矿、石英等。最佳还原条件为 :温度 10 0 0℃ ;碳酸钠加入量 6 %～ 7% ;还原剂木炭加入量 2 5 %。锑还原回收率为 83 %。
The chemical and mineral composition of antimonious oxide powder produced by fuming process is determined by X-ray diffraction and electron probe microanalyzer The reduction experiment of antimonious oxide is conducted The results indicate that antimonious oxide powder from fuming process is complex in composition and more impurities content compared to that from blast furnace, most of Sb 2O 3 are isometric crystal and a few are oblique crystal, the other minerals are amorphous crystal carbon, graphite, hematite, and quartz The optimum reduction parameters are 1000℃ reduction temperature, 6%～7% addition of sodium carbonate, and dosage of reduction agent 2 5% The recovery of antimony in reduction process is up to 83%
