摘要： 对以澳大利亚韦帕矿为后加矿和以氢氧化铝为后加矿的溶出矿浆进行赤泥沉降性能的研究,考察了无絮凝剂添加以及以淀粉和A-1000为絮凝剂时对矿浆沉降性能的影响,同时对增溶溶出矿浆与未进行增溶溶出矿浆液的赤泥沉降性能进行了对比性研究.结果表明:矿浆经过增溶溶出过程后,与未进行增溶的矿浆相比沉降性能得到明显的改善.增溶溶出矿浆在沉降过程添加适量的絮凝剂会获得更好的溶出效果,其中以韦帕矿为后加矿的增溶溶出矿浆的沉降性能更加优良.

Abstract: The settling performance of digested red mud pulp during sweetening process was investigated with Weipa ore from Australia and Al(OH)3 as additions. Blanked experiments without flocculant and with starch and A-1000 as flocculants were conducted comparatively to clarify the effect of flocculant on the settling performance of red mud pulp, as well as the settling performance of sweetened red mud pulp in comparison with that unsweetened. The results showed that applying the sweetening process to treating ore can obviously improve the settling performance of digested pulp, and the digested pulp with Weipa ore as the addition during the sweetening process has better settling performance than without addition or using other flocculants.
