Optimum coke amount was found to be 10% of the slag weight in an opentop furnace for a 1 hour reduction time in the temperature between 1703 K and 1753 K. Similar conditions in a closedtop furnace resulted in higher cobalt and copper contents of the metallic matte, recoveries and reduction rates, as compared with the opentop furnace.

Aug 20, 2008· In the modified Caron process using the solvent extraction nickel/cobalt separation step, this has the effect of increasing the requirement for the use of hydrogen peroxide, which is added to the nickel and cobalt containing solvent extraction stage feed liquor, to convert the majority of the cobalt to the trivalent state. ... Coal or coke as a ...
In chemistry, a reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowest. It is used to summarize information about the reactions of metals with acids and water, double displacement reactions and the extraction of metals from their ores
Une partie de l'électrolyte usé entre dans le circuit de récupération du cobalt et est purifié par l'enlèvement du fer, du cuivre, du nickel, et du zinc avant la précipitation du cobalt en hydroxyde de cobalt. Ceci est accompli par l'addition de plus de chaux pour élever le pH jusqu'à ce .

The specified sulfidization can be used in a mixture with other known sulfidization, such as pyrite or gypsum, reduces emissions of sulfur dioxide into the atmosphere, increasing the extraction of Nickel in matte and reducing lumpy consumption of metallurgical coke. 3 fcrystals, 1 table.
Coke is a pure form of coal that contains carbon and is essential in the extraction of metals from their oxides. There is another process in which the galena mineral can be smelted through. It also requires two chemical reactions to occur within the furnace. 1) Due to the sulfur content, carbon from the coke will not be able to reduce lead.
