【摘要】：研究輝鉬礦微波焙燒工藝,通過單因素實(shí)驗(yàn)確定主要影響因素和水平后,利用響應(yīng)曲面法考察焙燒時(shí)間、物料質(zhì)量、焙燒溫度對(duì)焙燒效果的影響,建立了用于可溶鉬(MoO_3)比例及S含量預(yù)測(cè)的多元回歸模型,優(yōu)化了工藝條件。結(jié)果表明,焙燒溫度、焙燒時(shí)間和物料質(zhì)量均對(duì)焙燒效果影響較大,按影響程度大小排序?yàn)?焙燒溫度焙燒時(shí)間物料質(zhì)量。優(yōu)化的工藝條件為:焙燒時(shí)間56.95min,物料質(zhì)量8.33g,焙燒溫度649.55℃;此條件下采用微波焙燒后鉬焙砂中可溶鉬(MoO_3)比例和S含量分別為94.3%和0.054%,而采用傳統(tǒng)電阻爐加熱焙燒后鉬焙砂中可溶鉬(MoO_3)比例和S含量分別為85.5%和0.471%,表明微波焙燒大大提升了輝鉬礦的氧化效果。
[Abstract]:The microwave roasting process of molybdenum was studied. After determining the main factors and levels by single factor experiment, the effects of roasting time, material quality and calcination temperature on the roasting effect were investigated by response surface method. A multivariate regression model for the prediction of soluble molybdenum (MoO_3) ratio and S content was established and the process conditions were optimized. The results show that roasting temperature, calcination time and material quality have great influence on the roasting effect. The order of influence is: roasting temperature roasting time material quality. The optimum technological conditions are as follows: roasting time 56.95 min, material quality 8.33g, calcination temperature 649.55 鈩，
