研究了在孔雀石上同时使用δ—氨基草酸和不同烷基的黄原酸盐对孔雀石可浮性、药剂吸附量及其影响。结果表明,孔雀石在黄原酸盐和δ—氨基草酸并用时,共可浮性良好。特别是δ—氨基草酸做为偶极离子存在时,在整个pH范围内都有良好的浮选效果。黄药的吸附量由于β—氨基草酸的加入 The malachite floatability, the amount of drug adsorbed and the effect of using both δ-aminooxalate and different alkyl xanthates on malachite were studied. The results show that malachite in the combination of xanthate and δ-amino-oxalic acid, a total of floatability good. In particular, δ-aminooxalate, which is present as a dipole ion, has a good flotation effect over the entire pH range. Xanthate adsorption due to the β-amino acid addition
