新型抑制剂y-As在硫砷分离中的抑制机理研究及工业应用

Study on the Inhibition Mechanism of the New Inhibitor y-As in the Separation of Sulfur and Arsenic and its Industrial Application

本文通过多组黄铁矿、毒砂的单矿物及人工混合矿进行试验,结果表明:y-As在适宜的pH范围内能有效的抑制毒砂,大大地降低毒砂的可浮性,可有效的实现硫砷分离;通过对抑制剂的红外光谱图及药剂作用前后矿物Zeta电位变化图分析,初步探明了y-As的抑制机理;y-As在工业生产上的应用发现,其对毒砂矿物的抑制作用明显。

In this paper,multi-group tests on the monominerals and artificial mixture of pyrite and arsenopyrite are conducted.The results show that y-As can effectively inhibit arsenopyrite in a suitable pH range,greatly reducing the floatability of arsenopyrite and effectively realizing the separation of sulfur and arsenic.The inhibition mechanism of y-As is preliminarily proved by analyzing the infrared spectra of the inhibitor and the Zeta potential change of the minerals before and after the action of the inhibitor.It's also found in the application of y-As in industrial production that it has an obvious inhibitory effect on arsenopyrite minerals.
