Experimental Study on Flocculation and Settlement of Copper Cobalt Ore Acid Leaching Residue
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.
