For galena, it can be seen from Fig. 7 (b) that in the spectrum of bare galena, the peak at 3524.5 cm −1 was related to the stretching vibration of hydroxy (–OH), and the peak at 1397.9 cm −1 was the characteristic peak of lead hydroxide (Chernyshova, 2003). These results suggested that a certain degree of oxidation appeared on the ...
The bulk chemical compositions of the selected slag tailing, presented in Table 1, primarily comprise Fe 2 O 3 (54.8%) and SiO 2 (28.1%), with minor quantities of Al ... sulfides (galena, sphalerite, arsenopyrite, and chalcopyrite) are consistently observed in minor quantities within the selected slag tailing, aligning with findings from other ...

The particle size distribution of the molybdenite flotation tailings associated with galena (measured by laser scattering in a Helos and Rodos granulometer) appears in Table 2. …
The flotation was conducted for 5 min, and rougher lead concentrate and tailing were obtained, and then they were dried and weighed for lead content detection to calculate lead recovery. Each flotation test was repeated three times and the average value was reported. ... As can be seen from the table, when BET is adsorbed on galena surface, the ...
The mineral purification process is a critical step in obtaining high-purity metals. The purification process for galena ore mined from Ruwai, Central Kalimantan, Indonesia, has never been studied. In this research, the flotation process was done in a flotation column with KEX and MIBC used as a collector and a frother. The results showed that the optimum flotation …

Sphalerite (ZnS), galena (PbS) and pyrite (FeS2) are the important metallic sulphide minerals. These three sulphide minerals are often associated with each other, and …
In this study, the flotation method was employed to recover sphalerite and pyrite from a galena flotation tailing waste. The reagent scheme, including Cu 2+ activator and butyl xanthate (BX ...
Galena, sphalerite and pyrite represent the bulk of sulfide mineral; hOW'ever all particles are b~ altered and some cerussite and smithsonite are present.

At pH around 10.0, the adsorption amount of ATT on galena and sphalerite surfaces was ~1.2 × 10 −6 and 0.1 × 10 −6 mol·m −2, separately, which contributed to the enlarged difference of hydrophobicity and floatability between galena and sphalerite, resulting in a selective flotation separation of galena with ATT collector.

Dating of lead-zinc deposits is of critical importance for better understanding of ore genesis, but has long been a big challenge due to the lack of suitable minerals that can be unequivocally linked to the ore genesis and that can be used for tradition radiometric methods. This kind of deposits have simple mineralogy dominated by galena and sphalerite commonly associated with calcite …
Flotation has been extensively used to separate galena and sphalerite. Herein, a reagent scheme comprising aerofloat collectors and Zn 2+ and SO 3 2− depressants is developed for the flotation...

galena otation was MIBC because it is a versatile frother used in an extensive pH range [ 10, 11]. After galena adsorbs KEX, it would make a hydrophobic layer from the non-polar side (ethyl). Nitrogen gas was used in this experiment to minimize oxygen because oxygen could oxidize galena and disturb xanthate adsorption to galena. The nitrogen bubble

It oxidized the residual cyanide in cyanidation tailing pulp from 0.37 g/t to 0.14 g/t under test conditions, leading to easier flotation of chalcopyrite and galena than sphalerite and pyrite. (2) The obtaining Cu–Pb concentrate became much harder to separate than the original as a result of the residual reagents.
