摘　　要：以铜钴矿硫酸浸出渣为研究对象,开展絮凝沉降试验。结果表明,矿浆浓度为10.5%,絮凝剂浓度为0.1%时,AZ5005絮凝剂用量为70 g/t,底流矿浆浓度可达43.32%;5310絮凝剂用量为60 g/t,底流矿浆浓度可达45.30%。二者絮凝上清液均清澈,可以满足生产需求。矿浆浓度下降为5.5%时,两种絮凝剂的沉降速度变快。絮凝剂添加量为60 g/t时,AZ5005絮凝剂、5310絮凝剂的即时沉降速度分别达34.06 m/h、26.78 m/h,此时只有5310絮凝剂的上清液较清澈,可以满足生产需求。Taking the sulfuric acid leaching residue of copper cobalt ore as the research object,this paper conducts flocculation and sedimentation experiments.The results show that when the slurry concentration is 10.5%and the flocculant concentration is 0.1%,the dosage of AZ5005 flocculant is 70 g/t,and the bottom flow slurry concentration can reach 43.32%;the dosage of flocculant 5310 is 60 g/t,and the concentration of underflow slurry can reach 45.30%.Both flocculation supernatants are clear and can meet production needs.When the slurry concentration decreases to 5.5%,the settling speed of the two flocculants becomes faster.When the dosage of flocculant is 60 g/t,the instant settling rates of AZ5005 flocculant and 5310 flocculant reach 34.06 m/h and 26.78 m/h,respectively,at this time,only the supernatant of 5310 flocculant is relatively clear,which can meet production needs.
