Ubaldini et al have carried out experimental work to develop an innovative process, including an alkaline chemical pre-treatment and a conventional treatment, for gold extraction from refractory stibnite
The initial stage of mineralization in the orebody consisted almost exclusively of stibnite
followed by fluorite and calcite.
The company has also collected four large underground samples of stibnite
and gold-mineralized rock from the main vein in Tunnel D, which assayed as high as 2.
The highest grade parts of these new zones are associated with strong decalcification and commonly contain stibnite
Gold bearing stibnite
ore is mined at some 40,000 t/month from depths down to 1,000 m.
Previous investigators have reported five mineral species from the Tsumeb mine with essential antimony: famatinite, stibnite
, stibiconite and nadorite (Schneider, 1992), and biehlite (Schluter et al.
Locally present are stibnite
and chalcopyrite, as are lesser distributions of pentlandite (Ni,FeS), arsenopyrite, boulangerite (5PbS.
a Canadian junior company headquartered in Vancouver, has announced the results of an independent, NI 43-101-compliant preliminary economic assessment (PEA) of its Golden Meadows project near the historic mining town of Stibnite
in central Idaho.
Or suppose you are a mineral dealer in Changsha, China and one day a runner brings some mediocre stibnite
crystals into town to sell.
A list of Minproc's major column projects is given in Table 3 and these include installations for the flotation of pyrite, arsenopyrite, stibnite
, pentlandite and numerous copper minerals.
Specimens of most sulfide minerals, like chalcopyrite, pyrite, stibnite
, pyrrhotite, etc.
