摘要
介绍一种粉煤灰提取氧化铝的新方法。分析蒸压和煅烧两阶段主要影响因素对氧化铝提取率的影响,初步探讨低温蒸压和低温煅烧反应机理,确定蒸压和煅烧两阶段的最佳工艺条件。
The article introduces a new method of extracting alumina from fly ash. The major influences on alumina extracting ratio in low temperature stream-pressur and calcination stages are analyzed. The reaction mechanisms of low temperature steam-preassure and calcination are preliminarily discussed, and the best technologic parameters of the two stages are confirmed.
