of sphalerite and a few of marmatite. 54.78% Sn exists as cassiterite monomers, and 41.31% Sn is embedded in magnetite, existing as the form of tiny granule inclusion of cassiterite, which is proved......
(SGX) depressed arsenopyrite and pyrite strongly, but had a slight depression on marmatite by butyl xanthate. Zeta potential and adsorption isotherm showed that SGX adsorbed more strongly on arsenopyrite and pyrite than marmatite. LIU et al [3] found that ferrochrome lignin (FCLS) depressed chalcopyrite slightly, but depressed galena strongly. IR spectrum analysis indicated that FCLS adsorbed......
conditions. HUANG and SUN [7] studied the effects of 2-aminothiophenol on the separation of jamesonite and marmatite. The jamesonite and marmatite minerals had similar surface properties and their separation using a flotation method is inefficient. The result showed that 2-aminothiophenol, as a carrier, had good selectivity for separation of jamesonite and marmatite via flotation process. Jamesonite......
and marmatite could not be achieved at neutral pH. MBT is as powerful as the other three collectors for the chalcopyrite, but it is a more selective collector against copper-activated marmatite...-purity chalcopyrite, sphalerite and marmatite samples used in the test were obtained from Dachang concentrator, Guangxi, China. The chemical analysis of the chalcopyrite sample showed 35.90% Cu, 33.99......

found in zinc-bearing materials such as sphalerite or marmatite[7-8]. At present, many raw materials for recovering indium are the previously abandoned zinc smelter slag and leaching residue. These waste residues are calcined at high temperature, the flue dust was collected and then the zinc oxide flue dust (ZOFD) containing 0.1%-0.3% (mass fraction) indium was got[9-10]. Sphalerite and marmatite......
of the interaction of marmatite were studied by Tafel tests and impedance measurements in Ref. [10]. With the rising of pH, the corrosive current rises, and hydrophobic sulfur on mineral surface....

/marmatite using butyl xanthate as collector at pH 9.0. However, when DMDC dosage was larger than 1×10-5 mol/L, the recovery of chalcopyrite began to decrease. Obviously, the optimal DMDC concentration... occurred between the combined depressant polyaspartic acid/zinc sulfate (PZ) and Cu-activated marmatite surface through the copper atoms. As well known, the inhibitory effect of zinc sulfate on sphalerite......
