environmental conditions; (ii) removes a number of
disadvantages of current methods of industrial extraction
of silver, mostly related to technology costs and pollution
problems; (iii) the separation yields of silver are supperior
in comparison with those obtained by currently applied
processes to industrial scale; (iv) flexibility and
adaptability to the type of material that is extracted silver.
In addition the method can be adapted for the separation of
other metals from mine wastes and alluvial deposits. The
method described in the invention includes
methodological details for each stage of work and the
limits of applicability in relation to the source materials
for silver.

The invention relates to a method for the estimation of
conditions paleomediu based on the specific and selective
evolution, in relation with the changes of environmental
conditions, of mineral equilibriums and intre-phases
distribution processe of some minor elements. The method
allows the achievement of acceptable estimates for
sedimentary deposits and for Quaternare and Neogene
vulcanogen-sedimentary deposits in case of utilization as
marker geochemical processes of the precipitation-

In principle, the method consists in the thermodynamic
and kinetic interpretation of mineral processes sensible to
the changes of environmental conditions, knowing the
explicit thermodinamic and kinetic function which
governing these processes and the chemical and
mineralogical composition of marker minerals from
different current geological formations, respectively. The
estimations imprecision is determined by the accuracy
