Optimization of Flocculation and Sedimentation Process of High-Calcium Slurry in a Uranium Ore
Aiming at the problems such as low settling speed and poor solid-liquid separation effect of a uranium ore high-calcium slurry,static flocculation method was used to settle high-calcium pulp of a uranium ore,and the effects of flocculant type,dosage,mixed flocculant ratio and adding method on the settling effect were investigated.The results show that the settling rate of high calcium pulp can be significantly increased by the mixed flocculant prepared by WZ944 flocculant and 5330 flocculant.The optimal mass ratio of the two flocculants is 1:1,and the minimum dosage of the mixed flocculant is 35 g/t.The research results can provide reference for the optimization design of the uranium ore solid-liquid separation process.
