本文采用捕收剂苄基氨丙基二甲氧甲基硅烷（BADM）反浮选磁铁矿中的硅酸盐矿物。微浮选试验结果表明，在pH值为8的条件下，BADM对石英、石榴石、橄榄石和磁铁矿具有良好的可浮性。可溶性淀粉对磁铁矿有选择性抑制作用。以可溶性淀粉为分散剂，BADM为捕收剂，对磁铁矿中的三种硅酸盐矿物进行了混合浮选试验。为了探索这些发现的有效性，zeta电位进行了测量，结果表明，在BADM之前用可溶性淀粉调节硅酸盐并没有阻止BADM的吸附，而在磁铁矿表面上的吸附减少。
In this paper, a collector benzyl aminopropyl dimethoxymethylsilane (BADM) was utilized for the reverse flotation of silicate minerals from magnetite. The micro-flotation results showed that good floatability of quartz, garnet, olivine and magnetite was obtained at pH 8 in the presence of BADM. However, the depressant, soluble starch, showed a selective depression for magnetite. Separation of the three silicate minerals from magnetite was performed by mixed- mineral flotation experiments with the soluble starch as depressant and BADM as collector. In order to probe the validity of these findings, zeta potentials were measured and the results showed that conditioning of the silicates with soluble starch prior to BADM did not prevent the adsorption of BADM while the adsorption on the magnetite surfaces was decreased.
