Geological and geophysical data integration for delimitation of mineralized areas in a supergene manganese deposits
(Inst Geophysics Unam, 2014-04-01)
Geophysical methods are widely used in mineral exploration. This paper discusses the results of geological and geophysical studies in supergene manganese deposits of southern Brazil. Mineralized zones as described in ...
Manganese determination by GFAAS in feces and fish feed slurries
This paper presents a simple, fast and sensitive method to determine manganese in samples of feces and fish feed by graphite furnace atomic absorption spectrometry (GFAAS) by the direct introduction of slurries into the ...
EFFECT OF MANGANESE ON THE SECRETION OF MANGANESE-PEROXIDASE BY THE BASIDIOMYCETE CERIPORIOPSIS SUBVERMISPORA

Effect of cobalt(II) oxide and manganese(IV) oxide on sintering of tin(IV) oxide
Additions of 0.5 to 2.0 mol% of CoO or MnO2 onto SnO, promote densification of this oxide up to 99% of theoretical density. The temperature of the maximum shrinkage rate (TM) and the relative density in the maximum ...
