摘要:
为解决胶磷矿浮选中pH调整剂用量大、浮选流程复杂的问题，以新型磷酸酯药剂Gz92、氨类药剂AE35为白云石和石英的反浮选捕收剂，探索胶磷矿同步反浮选工艺。通过单矿物及人工混合矿浮选试验，研究了Gz92、AE35对白云石、胶磷矿、石英的捕收性能及分离选择性。结果表明：单一捕收剂在中性pH值条件下，Gz92对白云石表现出良好的捕收能力，AE35对石英表现出良好的捕收能力；Gz92与AE35联合对白云、石英表现出良好的捕收能力，对磷灰石无捕收能力；Gz92与AE35联合，一次浮选，可将人工混合矿P2O5品位从18.59%提高到31.91%，回收率67.96%。综合以上结果，利用Gz92和AE35在中性矿浆pH值条件下，可实现胶磷矿的同步反浮选。
Abstract:In order to reduce the dosage of pH regulator and simplify the flotation technological process, a new reagent system had been explored, which Gz92 and AE35 were used for collecting dolomite and quartz in flotation experiments. Through the single mineral experiments and artificial mineral experiments, the collecting and selecting appearance of Gz92 and AE35 were studied. The results showed that Gz92 has strong ability to collect dolomite, and AE35 has strong ability to collect quartz when the pH was 7 as the single collector in the pulp. When Gz92 and AE35 were added in the same pulp, they have strong ability to collect dolomite and quartz, but they have no ability to collect collophanite. In the artificial mixed mineral flotation experiment, the concentrate with P2O5 grade 31.91%, recovery of 67.96% can be obtained from the mixed mineral with P2O5 grade 18.59%. Based on the above comprehensive analysis, synchronous reserve flotation in nutral pH value was feasible.
