【摘要】 研究了黄料赤泥在溶出过程中发生膨胀的行为，发现絮凝剂过量、泥浆处理时间长将导致黄料赤泥膨胀加剧；提出了快速分离的方法；赤泥高效分离沉降槽的工业实践结果，证明了采用快速分离方法的正确性．更多还原

【Abstract】 The present paper deals with the volume expansion of low temperature sintered red mud in dissolve process. It was discovered that overdose of flocculating agent and too much settling time would cause serious expansion. A method of swift separation was proposed and the correctness of using this method was proved by industrial practice in the high efficient thickener.更多还原
