【摘要】 对新研制的反浮选降磷捕收剂(RFP138)体系中赤铁矿和胶磷矿的可选性及作用机理进行研究。赤铁矿和胶磷矿的单矿物及人工混合矿的反浮选分离试验表明:RFP138是赤铁矿和胶磷矿的良好捕收剂,在碱性条件下采用合适的抑制剂,能够有效地实现两种矿物的分选,将P含量由人工混合矿中的1.05%降至0.12%,且TFe的回收率达到91.30%。对RFP138溶液的化学行为及红外光谱进行分析,探讨RFP138对两种矿物选择性捕收的机理。更多还原

【Abstract】 The reverse flotation separation performance and mechanism of hematite and cellophane in the presence of RFP 138, a newly synthesized dephosphorization collector, were studied. Reverse flotation tests on monominerals and artificially mixed minerals of hematite and collophanite show that, this anionic collector performs excellently in reducing the phosphorus content in hematite. It can decrease the content of P in artificially mixed minerals from 1.05% to 0.12% and achieve the TFe recovery rate of 91.30%. The chemical behavior of solution and infrared spectra of RFP 138 were investigated to explore the selective collecting mechanism of RFP 138 to these two minerals.更多还原
