An option to remove manganese selectively from the solution by precipitation is a precipitation as MnO 2. The precipitate can be recycled to the smelter. 17. Alternatively, cobalt and manganese can be extracted together. Cobalt can then be stripped selectively, leaving the manganese in the organic phase.
In order to effectively separate and recover copper, cobalt, nickel and manganese from the leaching solution of ocean cobalt-rich crusts, a process of selective precipitation and extraction using precipitation with Na2S solution and solvent extraction with N235 extractant, was proposed. The optimum separation and recovery process conditions were determined through …
Finally, manganese and cobalt were separated with N-N reagent. Hence, the objectives of this study was to investigate the role of main factors such as N-N quantity, temperature, pH and reaction time, and also to determine what process controlled the rate of the dissolution of Mn or what kinetic model could be applied. ...
The recycling of rare earths is of high importance because of the possible supply risk of these elements in the near future. The method was tested for the removal of cobalt and iron from samarium and neodymium, respectively. The highest distribution ratios for cobalt and iron were found with 8.5 and 9 M HCl.

The extraction mechanism of cobalt ions by Cyphos IL-101 was suggested as that cobalt transferred to the organic phase from the aqueous phase in the form of [CoCl 4] 2−. 90.5% of Co and 86.2% of Li were recovered by precipitation after extraction separation in the forms of cobalt oxalate and lithium carbonate with the purity 87.4% and 74.2% ...
The possible carcinogenicity of cobalt, iron, lead, manganese, mercury, platinum, selenium, and titanium is reviewed, taking into account epidemiological data, the results of animal experimental studies, data on mutagenic effects and on other in vitro test systems. Of …
Manganese is the third most abundant transition metal, being widely distributed in the earth's crust. It heads group VIIa of the periodic table, lying above technetium and rhenium.

The SX group of the Parker Centre (CSIRO Minerals) has developed SX processes to separate manganese from nickel and cobalt (Cheng, 1999(Cheng,, 2000(Cheng, and 2001, and to recover nickel and ...
Separating gold, platinum and palladium. Bookmark this question. Show activity on this post. I've dissolved all 3 metals together in aqua regia due to them being mixed together as P t black, P d black and gold. I isolated the gold with no problem using sodium metabisulfate, but I am struggling to separate the P t and P d.
A process for the separation of nickel, cobalt or both from impurity elements selected from one or more of calcium, magnesium, manganese and chloride contained in a leach solution, the process comprising the step of subjecting the leach solution to solvent extraction using a carboxylic acid (such as Versatic 10), a hydroxyoxime such as LIX 63, a kinetic accelerator …
Manganese is an important metal with wide industrial applications in many aspects of social economy. Approximately 90–95% of manganese are consumed in the steel production, and the rest are used in the fields of non-ferrous production, battery, and dietary additives (Tan et al., 2004, Mei et al., 2011, IMnI, 2008–2016, China Manganese Industry, xxxx).
Contributions from industry and academia encompass metallurgical aspects of metals commonly associated with nickel and cobalt, such as copper and platinum group metals (PGMs). Specific focus areas of the collection include, but are not limited to mineral processing, metallurgy of nickel and cobalt ores, battery materials, recycling, recovery of ...
The dissolution ratio of zinc oxide is 92.6% at 90 °C and 60 min, whereas the dissolution of cobalt and manganese is negligible (5.37% and 0.05%, respectively). The selective dissolution of metal oxide M x O y in [Hbet][Tf 2 N]–H 2 O is explained using a U/x value that correlates with the lattice energy, U, of metal oxide.
In order to effectively separate and recover copper, cobalt, nickel and manganese from the leaching solution of ocean cobalt-rich crusts, a process of selective precipitation and extraction using ...
Based on the stratification characteristics of [Hbet][Tf 2 N] and aqueous solution, the efficient separation of zinc and cobalt is achieved by the selective dissolution and synchronous extraction of zinc from zinc-cobalt slag by the [Hbet][Tf 2 N]-H 2 O system in the heating and cooling process.
