Since the iron ions in the leachate exist in the form of Fe(II), iron-rich ranate after four countercurrent extrac-tions was rst oxidized with an equal volume of 1.84 g/L H 2 O 2. The pH was adjusted to 4 with the 5 mol/L NaOH solution to precipitate all the iron ions. Subsequently, the precipitation was ltered and dried overnight at 70
Aerospace material scraps are rich in cobalt and nickel. Our previous study showed that acid leaching is an effective method (Zhou et al., 2018), but a large amount of iron also entered the solution (>10 g/L).Iron has a negative impact on the recovery of cobalt and nickel (Guimarães et al., 2020).Currently, iron removal from solution is achieved through hydrolysis, …

Iron ore prices are forecast to maintain an average of $100/tonne in 2025 as China's sluggish property sector continues to subdue demand, says BMI, a unit of Fitch Solutions. According to a ...
The pre-solution in the producing iron phosphate comprises approximately 11.10 g/L of iron, 44.42 g/L of phosphorus, and 1.08 g/L of chromium. Notably, the concentrations of chromium and phosphorus significantly exceed the prescribed discharge standards, rendering direct disposal impractical and necessitating the implementation of effective ...
A Mining Company, Southern United States Challenge. Reduce the high levels of iron in the plant's raw water that leads to equipment fouling and high maintenance costs Keys To Success. Achieving iron levels at less than 0.5 ppm helps to improve the rate and cost at which the plant can develop caverns Solution
Fig. 2 illustrates the iron ore beneficiation process, particularly magnetic separation, resulting in the generation of inevitable tailings. Due to the characteristics of iron ores and the conditions during beneficiation, it is inevitable that approximately 2.5–3 tons of IOTs are generated for every 1 ton of iron ore concentrate produced [7].In 2019, the global annual …
A South African mining group is investigating the use of electrowinning (EW) to recover iron and H 2 SO 4 from an iron sulphate waste solution produced during metal beneficiation. For the purpose of this paper, the term electrowinning, as is commonly applied for this process, is …

Bacteria which oxidize the iron, commonly termed as iron-oxidizing bacteria have the potential of iron remediation from various kinds of water sources. These microbes biologically …
The aim of this work is to develop a route to reduce Fe(III) to Fe(II) using sodium dithionite and sodium metabisulfite as reducing agents. During the study, synthetic iron sulfate solution was used.
Iron tailings is a by-product of iron ore with the production rate of 1:2.5 to 1:3, which is usually dependent on mining condition (Ma et al., 2016). It was reported that its total amount accounted for about 39% among all tailings including various metallic and non-metallic tailings (Jiang et al., 2022).
