当为铜的分离的镇静剂面对丁基黄原酸盐从磁黄铁矿激活铁闪锌矿, Mercapto 有机化合物 DMPS 被使用。筹款测试 DMPS 让强壮的压抑在铜离子的缺席和存在在磁黄铁矿上完成,但是面对铜离子在铁闪锌矿上激活效果的 ofs 壁炉矿物质表演。铁闪锌矿的 Thefloatability 在 2-12 的酸碱值范围被改进。激活铜的铁闪锌矿能作为抑制用 DMPS 与磁黄铁矿高效地被分开的混合矿物质 hows 的筹款测试。红外线的吸附系列证明例如有很多个功能组嘘并且在 DMPS 的分子结构的 -SO_3。黄原酸盐和 DMPS 在硫化物矿物质上在他们的吸附竞争。
Mercapto organic compound DMPS was used as the depressant for separation of copper activated marmatite from pyrrhotite in the presence of butyl xanthate. The flotation tests of single mineral show that DMPS has strong depressing effect on pyrrhotite in the absence and presence of copper ion, but has activated effect on marmatite in the presence of copper ion. The floatability of marmatite is improved in the pH range of 2-12. The flotation test of mixture mineral shows that copper-activated marmatite can be separated efficiently fi'om pyrrhotite using DMPS as depressant. Infrared adsorption spectra demonstrate that there are a number of function groups such as -SH and -SO3 in the molecular structure ofDMPS. Xanthate and DMPS compete in their adsorption on sulfide minerals.
