利用能带模型讨论了黄药与硫化矿物的作用机理，阐明了捕收剂涂层稳定性与半导体能带结构的关系，并从理论上推导出了Barsky公式。研究了双黄药在矿物表面的脱附与矿物能级的相关性。结果表明，双黄药在矿物表面的脱附主要受矿物的电子能级控制，费米能级和边能级影响双黄药在矿物表面电化学吸附的稳定性。基于电化学分离能带模型，可以开发新的有机抑制剂。[
The interaction mechanism between xanthate and sulphide minerals was discussed by means of energy band model, and the correlation of stability of collector's coating with energy band structure of semiconductor was also illustrated, meanwhile the Barsky formula was deduced from theory. The correlation between desorption of dixanthogen on the mineral surface and energy level of mineral was researched. The results show that the desorption of dixanthogen on mineral surface is mainly controlled by electronic level of minerals; Fermi level and edge level can affect the stability of dixanthogen electrochemically adsorbing on the mineral surface. Based upon energy band model of electrochemical separation, new organic depressants can be developed. [
