摘　　要：羧甲基瓜尔胶属于强抑制力、高选择性的绿色天然多糖类有机大分子抑制剂。通过对智利某铜矿矿石采用羧甲基瓜尔胶抑制剂的选矿试验研究分析了药剂的性能。试验结果表明,羧甲基瓜尔胶是滑石的有效抑制剂,药剂用量120 g/t原矿条件下,羧甲基取代度为0.12、分子量为174万的瓜尔胶表现出的选择性抑制作用最明显,其抑制作用强于羧甲基纤维素钠。Carboxymethyl guar gum is a green natural polysaccharide organic macromolecules depressant with strong inhibition and high selectivity. The characteristics of carboxymethyl guar gum in the beneficiation process are analysed based on the test research on the application of depressants in beneficiation of Chilean copper ore. The results showed that carboxymethyl guar gum is an effective depressant of talc,and at a dose of 120 g/t ore,the selective inhibition of carboxymethyl substitution with 0. 12 and a molecular weight of 1. 74 million is the best. The inhibition effect of guar gum inhibitor is stronger than that of sodium carboxymethyl cellulose in the talc flotation.
