The recovery of zinc (Zn) and lead (Pb) from a citric leach solution of a non-sulfide type ore flotation tailing was examined utilizing sulfuric acid precipitation followed by solvent extraction using di(2-ethylhexyl) phosphoric acid (D2EHPA) as the extractant. Following lead precipitation (98.9%) with sulfuric acid, the pregnant leach solution was sent to solvent …
flotation tailing is particularly burdened with Pb, Zn, Cu, and Ni. In contrast to the neutral (Bor) and slightly acidic (Rudnik) pH reactions of technosols, the Robule ha d an ultra - acidic reaction

A laboratory scale, unstirred flotation column (Fig. 2) was used for the dynamic froth stability experiments in a modified Bikerman test.This set up is similar to the systems used in a variety of other studies (Ip et al., 1999, Cilek and Karaca, 2015, Li et al., 2017).The column was 157 cm tall with graduations on the front wall and a square cross sectional area of 139.2 cm 2.
Baking behaviour of CCS flotation tailing Acid baking is based on the decomposition (calcination) of the crystal structure of fayalite and the transformation of base metals (Cu, Zn, Co) into metal sulfate salts, which dissolve easily in water after sulfation. Oxide and silicate refractory structures must be decomposed by acid baking to extract ...
Floatation tailings (FT) are the main by-products of the hydrothermal sulfidation–flotation process. FT (FT 1 and FT 2) were obtained by treating two different …
The flotation tailing itself is located on the border of the urban and industrial parts of the city, and below it, there is a city wastewater collector. Due to its close proximity to the city center, the Old Flotation Tailings in Bor are also one of …
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 discharged at the last scavenger cell, and …
The RTH flotation tailing dump, located in the old open pit RTH in Bor about 500 m southeast of the Flotation Plant, has been in continuous operational work since 1985. The flotations tailing ...

Bioleaching of samples taken from depths of 10, 15, and 20 m from old flotation tailings of the Copper Mine Bor was conducted in shaken flasks using the extremely acidic water of Lake Robule as ...
The effect of four different oxidants on the dissolution of zinc from the flotation tailing in sulfuric acid solution was tested (Fig. 3 (a-d)). 87.1% Zn, 1.9% Pb and 11% Fe dissolutions were obtained using 1 g/L potassium permanganate (KMnO 4) as an oxidant addition in 1.0 M sulfuric acid solution at 40 °C leaching temperature and solid-to ...
The base and precious metal contents in flotation tailings are often comparable to those in the processed sulfide ores. The reserves of metals contained in flotation tailing in some sites may be estimated as significant due to the large volumes of wastes accumulated from decades of exploitation of some mineral deposits [15,17,21].
Appearance of tailing. (a) Flocculation. (b) Settling rate. What are the Variables and Factors of Flotation's Operation. The results to be obtained in flotation depend, more than in any other concentration process, on the proper coordination of a considerable number of operating variables. These variables are listed below: Ore Mineralogical ...
This study demonstrated the potential for heavy metal extraction from three mine tailings flotation fractions through bioleaching. Microbial consortia of acidophilic mesophiles or …
Combined with the washing process of a coal-preparation plant, kaolin was separated and recovered from flotation tailings, expanding the comprehensive use of flotation tailings and realizing the high value-added use …
A secondary cleaner flotation tailing sample containing Ni and Co obtained from a nickel flotation plant (Western Australia) was used in this study. The nickel is predominantly mineralised as pentlandite in a disseminated texture in an ultramafic ore. The elemental assay of the samples is shown in Table 1. It indicates the sample contained 0.79 ...
The flotation process performance of a refuse tailing fine coal slurry sample from a Colombian washing coal plant was studied using a mechanical flotation technique.

The classification of the flotation tailing removes large quantities of the slurry, and largely re-duces the load of gravity scavenging. The classification device and the water-only cyclone are the main characteristics of this new separator to distinguish from other columns or flotation equipment.
Pyrite flotation separation and encapsulation in tailings dams is proposed as a viable way to chemically stabilize tailings. Characterization of potential acid mine generation in tailings led to an innovative process in which acid-generating pyrite is separated by flotation from the coarse tailings and incorporated into the slime zone. This creates pyrite-free neutral …
The purpose of this study is to identify the physical, mineralogical, and electrochemical properties of copper flotation tailings as well as to investigate how polymer …
