It was believed that either alumina reacted with impurities in the iron powder or the surface diffusion caved the alumina particles to stick to the iron powder surfaces. Another approach was to use the air classifier mill to break up the sintered iron cakes into powders. The morphology of such particles was classified into 4 types in this study: irregular, equalaxed, near spherical, and flaky. The morphological differences were affected by the extent of sintering. The higher the extent of sintering, the stronger the inter-particle bonding.

此外，本实验利用空气分级气流粉碎机将还原后的烧结体进行粉碎，实验结果显示粉碎后的粉末形貌可以分为四种，不规则形、等轴形、近球形和片形，形貌上的差异是由於还原时铁粉烧结程度的不同，烧结程度越高，粉末间键结强度越强，因此粉碎过程中会产生高程度的塑性变形，以至於粉末形貌越来越接近球形，最后因粉末表面大量加工硬化产生破裂，形成片状碎屑。

Three schemes of dealing with AH wash liq uor of high soda concentration were analyzed and compared. The results show th at when the AH wash liquor of total soda concentration 95.06g/L is transferred d irectly to dilution tank, soda concentration in overflow of the 1st mud washer c ould be lowered by about 6g/L and soda loss in red mud attached liquor could be lo we red by 0.25 kg Na2O per ton of alumina and therefore saving cost of about 549 000 RMB per year; moreover, suspension in AH wash liquor could be re-dissolved in to diluted liquor and it is favor not only to rise pregnant liquor R p andimprove precipitation process, but also to avoid alumina loss cost of about 353?000 RMB per year by the suspension settling into red mud.

分析比较了处理高浓度氢氧化铝洗液的3种方案，结果表明：将全碱浓度为95.06g/L的氢氧化铝洗液直接送到稀释槽，可使赤泥一洗槽溢流浓度降低约6g/L ，每吨氧化铝赤泥附碱损失减小0.25kg氧化钠，每年可节省碱耗费约54.9万元；而且还能将氢氧化铝洗液中的浮游物反溶解进入稀释液，有利于精液 R p(氧化铝与苛性氧化钠的质量比)的提高，同时避免了其进入赤泥而被损失，每年可减少氧化铝损失费约35.3万元。
