The invention relates to an arsenopyrite flotation inhibitor which comprises the following components in parts by weight: 1-5 parts of modified sodium humate; 1-2 parts of an organic polybasic phosphonic acid chelating agent; 10-30 parts of calcium oxide; wherein the modified sodium humate is obtained by carrying out a reaction on sodium humate and 3-methoxy-4-hydroxybenzaldehyde. The inhibitor has a good inhibition effect on arsenopyrite and other arsenic-containing minerals, the inhibition capability on arsenopyrite minerals in the flotation process is enhanced, and the arsenic content in zinc concentrate and other flotation concentrates can be remarkably reduced. The inhibitor has a good inhibition effect on arsenopyrite and other arsenic-containing minerals, the inhibition capability on arsenopyrite minerals in the flotation process is enhanced, and the arsenic content in flotation concentrate can be remarkably reduced. 本发明涉及一种毒砂浮选抑制剂，包括如下重量份的组分：改性腐殖酸钠1～5份；有机多元膦酸螯合剂1～2份；氧化钙10～30份；其中改性腐殖酸钠为腐殖酸钠与3-甲氧基-4-羟基苯
