拜耳法赤泥强化沉降研究
Study on the Strengthening Sedimentation of Bayer Red Mud
摘要
Abstract
The physical characteristics and sedimentation Speciality of the Bayer red mud was studied according to the need of pile-up in this paper, compared the effect of different promoting settling agent for the settlement of red mud; The Reasonable proportion of the promoting settling agents was found through the orthogonal experiment: NaHm/ FDN/ SHMP/SDBS =1/11/2/3, In the concentration of 40% of the red mud mixed with 3. 4‰ promote settling agent, after 8 h the sedimentation layer concentration can reach 52.6% , after 24 h the sedimentation layer concentration can reach 59. 8%. Compared with natural sedimentation 24 h, settlement layer concentration improved by 27% ; To strengthen the concentrated red mud for curing, compared with natural sedimentation red mud solidified body,the cohesion increased by 50% , which improves the stability and safety of curing pile-up.关键词
