Abstract. This study presents the exploratory results on the nickel extraction from a serpentine flotation tailing sample containing sulfide and serpentine minerals at 0.3 wt.% of nickel. The nickel deportment analysis showed that almost 60% of nickel is hosted by sulfur-based minerals and 40% of nickel is in serpentine phase.
Key words: zinc; lead; flotation tailing; sequential leach 1 Introduction Zinc and lead are the most used non-ferrous base metals in the world after copper and aluminum. It is, however, estimated that around 26.36% and 24.39% of the mined zinc and lead, respectively, are lost in the processing activities and the mineral beneficiation …

For instance, the flotation process is performed with water containing 25–35% wt solid ratio and is consumed 1.9–3 m 3 water per ton of ore processed (Gunson et al., 2012; Li et al., 2019). However, the tailing slurry containing roughly 40–60% solids is discharged as a result of the process (Bleiwas, 2012). The primary environmental ...
A novel chemical scheme for the flotation of rutile from eclogite tailings has been developed in this work. It consists of lead ion as the activator, sodium fluorosilicate (SF) as the depressant, and styryl phosphonic acid (SPA) and n-octyl alcohol (OCT) as the collector.By using the proposed scheme to treat a feed ore of 4.5% TiO 2, a rougher …
It is generally true that cyanidation is capable of producing a tailing of lower gold content than flotation. At a price of $35 per ounce for gold this fact is of much greater importance than when gold was valued at $20.67 per ounce. The possible gold loss in the residue to be discarded will influence the choice of a method of treatment.
the removal of mineral-laden froth or tailing from the flotation cell. In industrial flotation column, the entrainment of gangue particle is common, so several stages of flotation columns are involved to meet the economically acceptable quality of the desired mineral in the product. In this review article, the details of various design ...
The highest biomass of Quercus Q1 robur (77.3 § 2.6 g) and Acer platanoides (76.0 § 4.9 g) was observed. A proper planting of selected tree species that are able to thrive on sewage sludge/flotation tailings could be an interesting and promising way to protect dams.
Flotation tailings are by-products of coal preparation plants, which do not only occupy cultivated land but also cause pollution. The high ash content and low calorific value of tailings limit their applications. Deashing is the precondition for the reutilization of flotation tailings. However, it is more difficult to remove ash content from flotation …
The main focus of this study is to interpret the process behavior of (fine to ultrafine) cassiterite from tin tailing residues through different flotation methods. Conventional froth flotation (CFF) and oil-assisted agglomeration flotation (OAF), using commercially available cassiterite collectors from Clariant, were chosen as processing ...
An example of flotation with innovative collector is the beneficiation of cassiterite fines from a tailing slime in the Datun concentration plant using froth flotation process with benzohydroxamic ...
Thus, S/L of 2/10 was determined to be the most appropriate condition for the dissolution of zinc from the flotation tailing, which was able to leave a considerable amount of iron and arsenic in the leach residue. 89.3% Zn, 12.3% Fe, 18.8% As were extracted into the leach solution using an acid concentration of 1.0 M sulfuric acid, a ...
The complex mineralogy of Sossego DAM copper tailing leads to the necessity to grind the rougher magnetite pellet feed to a P80 of 20 µm to liberate of magnetite and allow to produce a high ...
For instance, the flotation process is performed with water containing 25–35% wt solid ratio and is consumed 1.9–3 m 3 water per ton of ore processed …
The recovery of zinc from a flotation tailing using 17-different leaching agents, including inorganic and organic acids, alkaline solutions and chelating agents, was investigated. The effects of the lixiviant type, acid concentration, leaching temperature, leaching time, and solid-to-liquid ratio on the metals dissolution were studied. ...
Flotation of the tailing (Zn grade-recovery curve) in the presence of different concentrations of flocculant ([amine] = 356 g/t, [Na 2 S] = 3400 g/t [pine oil] = 60 g/t). It is worth mentioning that using superfloc N-100 caused adhesion of particles, which is likely to bring the silicate gangue particles to the concentrate, thus reducing the grade.
DESCRIPTION: Flotation with cyanidation of flotation tailings. This flowsheet has a gravity gold recovery embedded into the grinding circuit's ball mill discharge. ORE TREATED: Ores containing both oxide and sulphide minerals with gold or silver, or those with cyanicides which must he removed before cyanidation. …
1. Introduction. Froth flotation is an essential method to collect valuable minerals from gangue minerals, and is an industrial process involved with long time delay and multiple subprocesses (Aldrich et al., 2010, Mesa and Brito-Parada, 2019, Quintanilla et al., 2021, Shean and Cilliers, 2011).In the zinc flotation process, the zinc tailing is …

Thus, this research was performed to describe the behavior of important factors affecting the leaching of zinc from a tailing sample obtained from lead-zinc flotation circuit in ferric sulphate and sulfuric acid media. It was found that 0.5 mol L −1 ferric sulphate is enough to dissolve both oxidized and sulphidic minerals. Response surface ...

The production of fine coal particle wastes and by-products has increased as a result of continuous mining methods and …
The residual xanthate in the flotation tailing can cause environmental issues through contaminating of the nearby water resources as a result of poor design of the tailings dams. In this communication two modified bentonite adsorbents, namely acid-activated (H-Be) and aluminum-pillared (Al-Be) bentonite, were synthesized and used …
