本文详细阐述了新型捕收剂Ｈ（３１６）从包钢强磁中矿中分选稀土精矿的工业生产试验结果。结果表明，Ｈ（３１６）是一种选择性好、配制方法简单、不污染环境的稀土矿物捕收剂。与Ｈ（２０５）相比，稀土精矿产量和回收率均有提高，Ｎａ２ＳｉＯ３用量显著减少，每吨稀土精矿药剂成本降低了４４．２２元，使稀土选矿技术得到进一步提高。
This paper describes in detail the industrial production test results of the new collector H (316) for the separation of rare earth concentrates from the ferromagnetic medium ore in Baotou Steel. The results show that H (316) is a rare earth mineral collector with good selectivity, simple preparation method and no environmental pollution. Compared with H (205), the yield and recovery of rare earth concentrate increased, the dosage of Na2SiO3 decreased significantly, the cost of medicament per ton of rare earth concentrate decreased by 44.22 yuan, and the technology of rare earth beneficiation was further improved.
