“…The study considered the possibility of the interaction of water-soluble compounds of iron (II) with the sphalerite surface in water under conditions that the layer of iron (II) sulfide is the main product formed on the surface of sphalerite particles. It follows from previous research [8,19,21,22,36] in which the activation of sphalerite with copper (II) cations was studied.…”

“…The industrial experience of flotation of sulfide copper-zinc, lead-zinc and polymetallic ores shows that the improvement of flotation technology is essential for increasing concentrate grade and metals recovery [18]. Typically, this is achieved by the optimisation of flotation circuits, the installation of modern equipment and optimization of the reagent schemes of flotation [19,20]. One of the directions in the development of reagent schemes of flotation is the study of the effect of collecting agent on the mineral surface under bulk or selective flotation conditions [21][22][23][24][25].…”

The flotation recovery of sphalerite depends on the inorganic reagents concentrations in the liquid phase of suspension and pH. This paper presents the results of studies of the interactions of iron (II) containing ions with the sphalerite surface in water solutions at different pH levels. The thermodynamic and electrochemical studies were carried out to analyze possible interactions of sphalerite with iron (II) sulfate in a water environment and relate them to sphalerite flotation with potassium butyl xanthate and sodium dibutyl dithiophosphate. The results of the thermodynamic calculations revealed the possibility of interaction of the sphalerite surface with iron (II) hydrolysis products. The effect of the hydroxide ions concentration on precipitation of iron (II) hydroxides was examined. The findings showed that at pH = 8 there were no precipitates observed in water solutions of FeSO4. Increasing pH of the solutions from 8 to 12 resulted in the formation of iron (II) hydroxides. The potentiometric studies revealed that in slightly alkaline solutions the Fe2+ and FeOH+ cations are potential-determining. In conclusion, the flotation tests with thiol collectors show the activation effect of iron (II) sulphate on sphalerite at low dosage and pH 12. This is evident by a higher flotation recovery of sphalerite at these conditions.

“…In the flotation of a stibnite ore, stibnite has been declared as naturally hydrophobic in the presence of air or as partially hydrophobic on the basis of the critical surface tension of wetting (Ozcan, 1992, Popov et al, 1987, Herrera-Urbina et al, 1990, Fuerstenau et al, 2007. In addition, in practice, the particle shape, roughness and particle size, heterogeneous structure of the minerals to be flotation affect their surface properties and thus their buoyancy.…”

Efficient evaluation of antimony ores, which are on the critical raw materials list due to the supply risk by the European Union, is an important necessity. In this context, ore preparation and enrichment processes are very important during the process from ore to metal. Especially for sulfide antimony ores, the most common beneficiation method is flotation. Therefore, antimony ore consisting of stibnite mineral obtained from Tokat-Turkey region was used in this study. Due to the low antimony (5.06%Sb) and the high Arsenic (1.38%As) content, it is an important requirement to increase the Sb content of this ore by flotation, as well as to reduce the As content to certain levels. Stibnite as an antimony mineral and arsenopyrite as arsenic mineral, are minerals that have a sulphurous structure in mineralization and their flotation properties are quite close to each other. Therefore, in this study, it is aimed to selectively separate the bulk concentrate taken from rougher flotation by cleaning steps. A bulk sulfur concentrate with 24.54% Sb and 3.69% As content obtained as a result of the rougher flotation was obtained with a recovery of 98.9%. This product was subjected to 6 stages of cleaning flotation and a concentrate with a content of 63.8% Sb and 0.31% As was produced with an antimony recovery of 83% Sb.

“…In order to reduce losses during the extraction of minerals, the technology with backfilling is used [2]. Despite the many positive factors of geotechnology with backfill such as rock pressure control [3]; improving safety [4]; minimizing the impact on the environment [5 -7], it has a significant drawback: high dilution, which negatively affects the benefication process [8,9].…”

The practice of benefication of copper-zinc ores has established that the production of high-quality zinc concentrates is impossible without the addition of sphalerite and pyrite modifiers to various flotation operations. This article present the result of study of the effect of copper (II), zinc and iron (II) sulfate on the froth flotation of sphalerite by sulfhdryl collectors. Typically, it is achieved through optimisation of flotation circuits, installation of modern equipment and changing the flotation reagents modes. Therefore, the floatability of sphalerite in an alkaline lime medium was studied with the addition of one of these metal sulphates to the mineral flotation operation. The effect of each of copper (II), zinc and iron (II) sulphates on the floatability of sphalerite was studied by flotation of the mineral and by potassium butyl xanthate and sodium dibutyl dithiophosphate at pH = 8, 10 and 12.
