Due to the different metal compositions the spent Ni-Cd and Ni-MH batteries must be recycled separately (Barandas et al., 2007a, Barandas et al., 2007b). Hydrometallurgical routes are the basis of processing ...
In the second stage, the residual iron and cobalt are separated from nickel by selective oxidation of cobalt. Bleaching powder and sodium oxychloride were separately used for this purpose. About 80 to 85% of the iron may be precipitated in the first stage, with practically no nickel or cobalt loss.

Titrimetric microdetermination of nickel and cobalt, separately and in presence of each other. Titrimetrische Mikrobestimmung von Nickel und Kobalt, allein und in Mischung. Short Communications; Published: 26 October …
reduction in order to recover nickel and cobalt separately. Process description Development work on the cobalt recovery process was started in the Research & Development Div. of Sherritt Gordon Mines as early 1952. By the end of 1954, enough data had been accumulated to allow preliminary pilot plant operations to be started. ...
A product containing 5.13 pct Ni and 3.47 pct Co was obtained at a cobalt and nickel recovery of 84 pct. The selectivity index for the chalcopyrite-siegenite separation was 5.5. The tailings from this separation became a cobalt-nickel concentrate, since the cobalt and nickel content had two to three times the economic value of the residual copper.
The Moa Bay Nickel-Cobalt Plant, situated in Cuba, is a significant processing facility in the region. It was first established in 1985 and primarily focuses on the extraction and refining of nickel and cobalt. ... Each commodity is considered separately and commodities cannot be combined to arrive at a significant size. The tonnage thresholds ...
Herein, Ni/Co bimetallic phosphides encapsulated into nitrogen-doped dual carbon conductive network were synthesized and applied as LSB separator for the first time using binary metal Ni-ZIF-67@PDA as precursor through successive carbonization and phosphorization processes.When used as the modified separator, the carbon skeleton could provide a physical …

Cobalt, nickel and their compounds are in regular demand and have wide range of applications based on their different properties. They are widely used in different sectors including batteries, alloys, catalysts, electroplating etc. Cobalt is also used to stain glass, make tiles, ceramics and pottery.
The extraction of cobalt is more negatively affected by an increase in pH compared to nickel extraction; this same observation was documented in Cameron (2011); Cameron et al. (2013) with six different nickel sulphide ores containing pentlandite and pyrrhotite as the primary nickel and cobalt carrying minerals. These observations are somewhat ...
The separation behaviors of nickel and cobalt in a LiCl-KCl molten salt containing NiCl 2 at 550 °C were investigated for the decontamination of cobalt in a contaminated nickel alloy. The electrochemical separation of Co from Ni was demonstrated to be feasible, because it is thermodynamically stable in the molten salt as CoCl 2 as long as ...
