Effect of Manganese on Silver Leaching

In Mexico and elsewhere there are large bodies of valuable silver containing 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 in the is not invariably accompanied by refractoriness of the silver ...

    This reduces all of the to oxide, which is a leachable form. The then travels through a grinding circuit to reduce the particle size of the to between 150–250 μm, this increases the surface area to aid in the process. The is then added to a tank, which contains sulfuric acid and ferrous iron.

    [Bacterial leaching of manganese ores].

    Leaching of various types of ores, containing 12-30% manganese, by the thiobacterium Acidithiobacillus ferrooxidans was studied. Leaching of reduced ores manganocalcite and manganiferous limestone was mediated mainly by degradation of manganiferous minerals by sulfuric acid produced in the course of

    was leached from a low-grade LGMO using banana peel as the reductant in a dilute sulfuric acid medium. The effects of banana peel amount, H 2 SO 4 concentration, reaction temperature, and time on Mn from the complex LGMO were studied. A efficiency of ~98% was achieved at a time of 2 h, banana peel amount of 4 g, temperature of 120 ...
