Effect of Manganese on Silver Leaching

Mar 17, 2017  The mere presence of manganese in the ore is not invariably accompanied by refractoriness of the silver because the writer has known of an instance where ores of apparently similar composition and character and coming from adjacent mines behaved quite differently, one yielding only 50% of its silver

Simultaneous leaching of manganese and silver from ...

Apr 01, 2003  The elementary condition for the simultaneous leaching of Mn and Ag is that Mn 2+ and Ag + must coexist in the leaching solution. In order to investigate the thermodynamic feasibility of extracting manganese and silver simultaneously, Eh–pH diagrams of the Mn–H 2 O and Ag–H 2 O systems were drawn. Fig. 1 is the overlapped Eh–pH diagram at standard conditions (a=1 M, p=1 atm).

Silver mining - Wikipedia

Once silver ore has been removed from a mine, it is crushed into a fine powder. Silver is commonly extracted from the powdered ore by smelting or chemical leaching. Silver's melting point occurs at 962 o C (1764 o F, 1,235.15K). As such, industrial metallurgic processes are needed to prepare silver for commercial purposes.
