研究了一种新的巯基本并噁唑类合成药剂5-甲基2-巯基本并噁唑。实验室与半工业实验表明该试剂对几种复杂矿石中的硫化铜矿物表现出很强的选择性捕收作用。不久的将来可望开始工业生产。使用原位博里叶变换红外技术、吸附试验、电动电位测量与哈里蒙德管浮选试验研究了该试剂与纯辉铜矿的作用方式。傅里叶变换红外研究揭示了表面相的本质。面积法求得的吸附等温线反映了表面产物的定量变化，从而能在各种试剂浓度下测量表面覆盖率。电动电位用以证实各种浓度范围内各组分的稳定性。得到的有关结果揭示出该试剂与表面的化学作用以及表面的排列情况。
A novel 5-methyl 2-mercaptobenzoxazole, a novel thiol-based oxazole-based synthetic reagent, was studied. Laboratory and semi-industrial experiments show that the reagent shows strong selectivity for copper sulphide minerals in several complex ores. Industrial production is expected in the near future. In-situ Fourier transform infrared spectroscopy, adsorption experiments, electrokinetic potentiometry and Halmon tube flotation experiments were used to study the interaction between this reagent and pure chalcopyrite. Fourier transform infrared studies reveal the nature of the surface phase. The area-based adsorption isotherms reflect quantitative changes in the surface product, allowing surface coverage to be measured at various reagent concentrations. The electrokinetic potential is used to confirm the stability of the components in various concentration ranges. The results obtained reveal the chemistry of the reagent and the surface as well as the surface alignment.
