Flotation separation of marmatite from pyrrhotite using DMPS as depressant SUN Wei(孙 伟), LIU Run-qing(刘润清), CAO Xue-feng(曹学锋), HU Yue-hua(胡岳华) School of Minerals Processing and Bioengineering...; Abstract: Mercapto organic compound DMPS was used as the depressant for separation of copper activated marmatite from pyrrhotite in the presence......
: starch; diaspore; reverse flotation; depressant  ..., competitive adsorption and electrostatic repulsion between depressant and cationic collector, and strong interaction of depressant with the metallic ion of mineral[1]. Accordingly, selective depression......

: The depression mechanism of zinc sulfate (ZnSO4) and sodium dimethyl dithiocarbamate (DMDC) as the combined depressant on sphalerite was investigated by micro-flotation experiments, ion complexing tests... surface more hydrophilic than ZnSO4 or DMDC. XPS analysis indicated that the combined depressant could prevent collector adsorbing on the Pb-activated sphalerite surface by a competitive adsorption method......
