using CMC (carboxymethyl cellulose) as a depressant were studied through flotation tests, adsorption measurements, ζ potential tests and co-precipitation experiments. The results show..., such as Na2SiO3, CMC and fluorocompounds [3]. CMC is a commonly used silicate depressant and has been used in separating sulphide minerals from gangues containing chlorite [4]. Carboxymethyl cellulose......
), which generally act as depressant and collector, respectively, in the reverse flotation of bauxite, was investigated using starch-iodine tests. The results obtained from the blue-value measurements...; dodecylamine; reverse flotation 1 Introduction Over decades, starch has been practically used as depressant and flocculant in the minerals processing industry for froth flotation [1......

复杂高硫金矿石浮选试验研究何桂春1(1.江西省赣州市江西理工大学资源与环境工程学院)摘 要:某高硫微细粒金矿石成分复杂,金与硫化矿物以及硫化矿物之间共生关系密切,分选难度大.试验采用工艺方法:亚硫酸钠-硫酸锌复合抑制剂抑制闪锌矿等硫化矿物,优先浮金;浮金尾矿用亚硫酸钠抑制黄铁矿,硫酸铜活化闪锌矿浮锌.试验结果表明,金精矿金品位达65.38%,回收率56.31%;锌精矿锌品位43.73%,回收率78.54%,取得了较好的技术指标.关键词:金矿石; 硫化矿物; 微细粒; 浮选; 锌......
could be the "mineral depressant" of hematite using sodium oleate as collector. The reasons for that are concerned with sodium oleate consumption and the adsorption onto hematite of dissolved species... be the "mineral depressant" of hematite using sodium oleate as collector. In order to further validate the depressing effect mechanism of Ca2+ on hematite, the XPS analysis of hematite before......
. It has electrochemically active sulfhydryl residues in molecular structure. OVA adsorption on pyrite as an alternative depressant was investigated by cyclic voltammetry, FTIR spectroscopy... between depressant and pyrite. In this work, possible adsorption mechanisms of ovalbumin (OVA) on pyrite were discussed. OVA is a relative high molecular mass monomeric glycoprotein. OVA contains single......
