Study on Experiment of New Collector DT-1 Flotation Molybdenum Ore

The new type collector DT-1 which is good at flotating molybdenum was made and investigated for aiming at gangue being difficult to sediment and water using in flotation being difficult to reuse because of a lot of dosage of sodium silicate in a molybdenum flotation of Liaoning province.The results show that the collector DT-1 has stronger collecting power and well selectivity for molybdenite. Compared with traditional kerosene and xanthate flotation,this process using the new collector could have a good index with 60% sodium silicate. The closed-circuit test results are as follows:the molybdenum concentrate of 53.04% with the molybdenum recovery of 95.02% is obtained.
