four zones (Valls Álvarez, 1995b), gold, copper, silver, zinc, arsenic and lead were found to concentrate mainly in the siliceous zone. Gold also was found concentrated inside the iron-altered zone, while the carbonate-rich zone is almost barren of ores. It is commonly assumed that gold is transported in the (+1) oxidation state (McKibben et

Effect of Manganese on Silver Leaching

In Mexico and elsewhere there are large bodies of valuable silver ore containing manganese which present great, and hitherto insuperable, obstacles to a satisfactory extraction by cyanide. The proportion of the silver that is soluble in cyanide varies greatly and may be as low as 5% only. The mere presence of manganese in the ore is not invariably accompanied by refractoriness of the silver ...

Method for recovering silver from refractory

(a) applying a manganese reductase enzyme produced by Bacillus polymyxa, strain D-1, ATCC-55030, to the ore together with a suitable electron donor at conditions of temperature and pH suitable for enzymatic catalysis of manganese reduction, until a sufficient amount of the manganese is reduced from Mn(IV) to Mn(II), thereby solubilizing the manganese and disrupting the manganese dioxide crystal lattice so as to release the complexed silver

Manganese - Wikipedia

Manganese (II) chloride crystals – the pale pink color of Mn (II) salts is due to a spin-forbidden 3d transition. The most common oxidation states of manganese are +2, +3, +4, +6, and +7, though all oxidation states from −3 to +7 have been observed. Mn 2+ often competes with Mg 2

Sedimentary exhalative deposits - Wikipedia

Sedimentary exhalative deposits are ore deposits which are interpreted to have been formed by release of ore-bearing hydrothermal fluids into a water reservoir, resulting in the precipitation of stratiform ore. SedEx deposits are the most important source of lead, zinc and barite, and a major contributor of silver, copper, gold, bismuth and tungsten.
