The Use of Polyacrylamide as a Selective Depressant in the Separation of Chalcopyrite and Galena
DownloadSpring 2013
High molecular weight polyacrylamide (PAM) was tested as a potential selective depressant in the differential flotation separation of galena and chalcopyrite using potassium ethyl xanthate (KEX) as a collector. In single mineral flotation, PAM depressed chalcopyrite while galena was floatable....

Theoretical study on reactivity of different sulfide collectors and their binding affinity toward Cu(II), Zn(II) and Pb(II) ions.
DownloadSpring 2016
Collectors are one of the most important ingredients of froth flotation in mineral processing, as they selectively render the desired minerals more hydrophobic than others. Current crop of sulfide collectors interact with almost all sulfide minerals. This necessitates the use of complicated...

The stability of the ether bond affects coal dissolution during direct coal liquefaction and aliphatic ethers are reportedly the most reactive of the oxygenate classes during liquefaction. Some ether compounds are also persistent to high temperature during coal pyrolysis. The thermolysis of ether...
