Copper recovery from the tailings of slag flotation by leaching and roasting
(2006)
The sulphuric acid and the hydrogen peroxide leaching and roasting with/without addition of NaCl and Na2SO4of tailings of Black Sea Copper Works Flotation Plant (in Turkey) were studied. The native copper, covellite, ...
Electrochemical investigation of pyrite floatability and hydrophobicity with Dithiophosphate and Fe-Ions
(2006)
This research was performed to elucidate the role of DTP and Fe ions on the hydrophobicity and floatability of pyrite in chemically controlled electrochemical conditions between 0-500 mV vs. SHE. Experimental works suggested ...
Dissolution of chalcopyrite concentrate by dichromate ions in sulphuric acid medium
(2006)
In this study, the leaching conditions of chalcopyrite (CuFeS2) concentrate enriched through flotation of Menka Corporation Cu-Pb-Zn complex ore in sulphuric acid medium under effect of potassium dichromate were investigated. ...
Role of treatment on dithiophosphate adsorption on chalcopyrite
(2006)
Role of treatment on the electrochemistry of dithiophosphate (DTP) adsorption on chalcopyrite was investigated by cyclic voltammetry (CV) technique. Measurements were made in slightly acid, neutral and alkaline conditions. ...
Recovering of Ni, Co and Cu from Divrigi Iron Plant tailings by sulphuric acid oxygen pressure leaching
(2006)
Turkish Iron and Steel Company at its Divrigi concentrator plant produces magnetite concentrate for sintering using dry and wet magnetic separation. Nearly 750.000 tons of tailings are sent to tailings dam from Divrigi ...
Effect of the solution surface tension for flotation, flocculation and oil agglomeration processes
(2006)
The wettability of solid or mineral particles is known to be an important parameter which influences many technological processes including flotation, flocculation, oil agglomeration, solid-liquid separation, adhesion, ...
