脆硫铅锑矿制备锑白影响因素的研究

Study on the influencing factors of preparing Sb_2O_3 from jamesonite

用脆硫铅锑矿制备Sb_2O_3,并对影响锑白粒度及白度的一些工艺因素进行了研究.结果表明:锑白粒度随着氧化温度的升高而增大,随着鼓风量的增大而减小;锑白白度则随着氧化温度的升高及鼓风量的增大先上升后下降,当氧化温度为650℃、鼓风量为理论值2倍时,所获得锑白的白度为96～97度,同时需控制铅锑合金中杂质的含量低于0.01%.

Sb2O3 prepared using jamesonite was investigated including some technological conditions about effecting particle size and whiteness of antimony oxide. The results show that the particle size of antimony oxide increases as the oxidizing temperature rises, and it reduces as the volume of blast increases. Whiteness of Sb2O3 goes up first and then down as the oxidizing temperature rises and the volume of blast increases. When the temperature rises up to 650℃ and the actual value is as twice as theoretical value of the volume of blast, the whiteness of Sb2O3 is up to 96-97 degree. At the same time the impurity content in PbSb alloys must be controlled under 0.01%.
