摘要
在赤铁矿与霓石的弱酸性浮选分离体系中 ,α位被—OH、—SH取代的小分子有机酸如乳酸、羟基乙酸、巯基乙酸、葡萄糖酸等对霓石具有良好的选择性。对其结构与性能的关系进行了详细的研究 ,并提出了选择性吸附的模型来说明其对霓石的抑制机理。
In the weak acidic flotation separation system of hematite from aegirine,low weight molecule organic acids such as lactic acid, hydroxy acetic acid,mercapto acetic acid and glucose acid which is substituted with -OH and -SH at α carbon, have a good selective depression for aegirine. The relationship between the structure and performance of the depressors is investigated and a mathematical model of selective adsorption is developed to explain its depressive effect on aegirine.
