摘要
以选矿-拜耳法产业化暴露出溶出率偏低的问题为研究对象,从实验室研究出发,探索了不同的石灰添加方式对溶出效果的影响,发现了直接添加石灰粉优于水化石灰乳、水化石灰乳又优于循环碱液化石灰乳的规律,并分析了原因,为选精矿“双流法”高温强化溶出工艺改进指明了方向。
Different lime adding types on concentrated bauxite digestion different show digestion rates of the ore- dressing Bayer process, the paper found that result of the lime powder directly adding type is better than that of the hydrated lime milk adding, but the hydrated lime milk adding is better than the lime milk slaked by the recycled soda liquor according to the test of the laboratory. And it analyzed the reason. The test study pointed out the direction to improve the concentrated bauxite ＂double - stream＂high temperature intensive digestion process.
