Beneficiation Of Artvin-Cerattepe copper-zinc ore by flotation

چکیده
The Cerattepe (Artvin) mine contains volcanogenic massive sulfide (VMS) deposits in northeastern Turkey. This is a kuroko type deposit located Late Cretaceous volcanic, intrusive and sedimentary rocks, has structure with dense alteration stages. In this study, batch flotation tests were carried out to determine the behavior of new sample (mix ore), that was combination two different ores behaviors. mixed ore 2.18% Cu, 1.46% Zn, (Cu/Zn ratio 1.49) 38.35% Fe, 41.6% S content. An efficient separation copper minerals from zinc using conventional selective method could not be achieved due complex mineralogy very low liberation degree. Therefore, sequential resulted poor Cu recovery. effects parameters such as collector type, amount, particle size, pH conditions, investigated obtain bulk copper-zinc concentrate. best results obtained thionocarbamate (Aero 3894) dithiophosphine (Aerophine 3418A) reagents at d<sub>80</sub>=40 µm size. Under optimal conditions (grain µm, pH=11, amount reagent 60 g/t 3894), frother (MIBC)=50 g/t, solid ratio=32%, time=8 min), concentrate containing 13% 9.5% Zn yield 84.4% 88.9%. mass pull 13%. After rougher two-stage scavenger flotation, (rougher + products) 22%. Copper recoveries 91.8% 92.5%, respectively.

Beneficiation of a low-grade iron ore by combination of wet low-intensity magnetic separation and reverse flotation methods
Beneficiation of a low-grade iron ore was investigated by combination of the low-intensity magnetic separation and reverse flotation methods. The main constituents of the representative sample were 36.86% Fe, 8.1% FeO, 14.2% CaO, 13.6% SiO2, and 0.12% S based on the X-ray fluorescence, titration, and Leco analysis methods. The mineralogical studies by the X-ray diffraction, scanning electron mi...
متن کاملReprocessing of Sangan iron ore tailings by flotation
The Sangan processing plant consists of four consecutive low-intensity magnetic separation steps with the same magnetic field intensity of 1300 Gauss for upgradation of iron ore. Hence, the iron ore minerals with lower magnetic susceptibility or interlocked with gangue minerals have no opportunity for upgradation, and proceed to the tailing dam. Flotation is a powerful technique for upgradation...

A flotation pre-treatment study for the separation of enargite (Cu3AsS4) from chalcopyrite (CuFeS2) ores of different origins was investigated in this work. The copper ore bearing enargite mineral contained 5.87mass% As and 16.50mass% Cu while the chalcopyrite bearing ore contained 0.32mass% As and 21.63mass% Cu. The two ore samples were mixed at 7 : 3 (enargite : chalcopyrite) by weight ratio ...
