Experimental Study on Separation of a Molybdenum-lead Mixed Concentrate in Henan
In order to make efficient use of a molybdenum-lead ore in Henan Province,aiming at the problems of difficult separation of molybdenum and lead in the mixed concentrate,excessive lead content in the molybdenum concentrate,based on the study of the ore properties of the mixed concentrate,the key technical parameters of separation roughing were determined by single factor condition test.The orthogonal test method is adopted,taking the dosage of roughing water glass,DP-1 and sodium thioglycollate as inde-pendent variable factors,and the beneficiation efficiency as dependent variable factors,the optimal inhibi-tor reagent system for molybdenum-lead separation was determined.The results show that when the dosage of water glass is 3 kg/t,the dosage of DP-1 is 5 kg/t,and the dosage of sodium thioglycollate is 18 kg/t,the beneficiation efficiency is the best.On this basis,a closed-circuit test of one roughing,two scavenging and seven cleaning was carried out.Finally,a molybdenum concentrate with molybdenum grade of 53.28%,lead content of 1.07%and molybdenum recovery of 91.56%was obtained,which realized the efficient sepa-ration and recovery of molybdenum and lead.
