bioprocessing can be used to treat refractory gold-bearing sulfide ores as well the first step should, however, be mineralogical evaluation of the ore sample.
in order for an oxidized deposit to be formed, an original sulphide ore body must u.s.a.and vesuvius in italy (see this isssue) are examples of stratovolcanoes.
sulfide minerals are inorganic compounds. examples of sulphide ores are galena and zinc blende, copper glance, iron pyrite, cinnabar, argentite or the silver
eight of the major iron and base metal sulphide minerals, chosen because of their widespread occurrence (pyrite, pyrrhotite), role as the major ore mineral of a
there are two main types of copper ore of interest: copper oxide ores and copper sulfide ores. both ore types can be economically mined, but
vms deposits are among the oldest ore deposits on earth, with examples in the pilbara of western australia and the barberton and murchison greenstone belts of
the authors are developing a workflow to understand sample and deposit amenability to isr processing. a south australian low-grade iron-oxide
complex sulfide ores are fine-grained, intimate associations of chalcopyrite (cufes2), sphalerite (zns) and galena (pbs), disseminated in dominant pyrite, and
in a few deposits, however, magnetite is preceded by pyrite or less commonly by other sulphides. in exceptional examples, as at kaveltorp, sweden, a series of
chalcopyrite is another major mineral for nickel sulfide ores that must be considered notable examples include sulfide minerals, iron-rich sediments, coals,
galena is the natural mineral form of lead sulfide (pbs). the examples are zinc-lead-silver deposits of red dog, northwest alaska, mcarthur river, mt isa,
not until the middle of the nineteenth century, when a substantial body of inorganic chemistry had begun to accumulate, were metals produced
chalcopyrite is another major mineral for nickel sulfide ores that must be for example, a report on surface water pollution from mining observed that the

the sulfide class minerals comprise an economically important class of minerals. most major ores of important metals such as copper, lead and silver are
an understanding of the genesis of sulphide-ore deposits has developed through separating sulfide minerals from each other, for example, separating
a typical example of a nickel sulfide plant operating with highly floatable talcose gangue is at trojan mine in zimbabwe. the zimbabwean sulfide deposits contain
the hangingwall to the deposit is broadly related to a more mafic sequence of volcanic rocks, either andesite (examples being whim creek & mons cupri, western
for example, brenan. & rose (2002) suggested a modification of the pgm collection model, with pgm crystallizing first, followed by base metal sulphides
bioleaching is one economical method which can be applied to leaching of low grade copper ores (akcil, 2004) bioleaching employs microorganisms for example
there are two main copper ore types of interest, copper oxide ores and copper sulfide ores. both ore types can be economically mined, however,
