The cleavage planes between prismatic stibnite crystals have been infilled by sphalerite. |
|
There were shops full of green and purple fluorite, ferberite and arsenopyrite, and spessartine and stibnite. |
|
Commonly associated minerals include orpiment, stibnite, a variety of sulfides and sulfosalts, calcite, and barite. |
|
Some of these veins reached the surface where, in the enclosing gossan, the stibnite has been subjected to oxidation. |
|
Sodium sulfide solutions are effective leaching agents for the concentration of stibnite from ores. |
|
The fluids were trapped in permeability-controlled positions within anticlinal zones, where fluid cooling induced deposition of stibnite and sulphosalts. |
|
There, gold with arsenopyrite and stibnite occurs along the northwestern contact of the Saint George Batholith for at least 4 km. |
|
The metallic form is considered to be relatively inactive whereas stibnite is extremely toxic to humans. |
|
Small stibnite deposits are found in Algeria, Bolivia, China, Mexico, Peru, South Africa, and in parts of the Balkan Peninsula. |
|
High-grade or enriched stibnite reacts directly with scrap iron in the molten state, liberating antimony metal. |
|
The metal can also be obtained by conversion of stibnite to the oxide, followed by reduction with carbon. |
|
When exposed by breaking open the quartz, the paakkonenite crystals are virtually identical in appearance to stibnite and exhibit a similar ease of bending. |
|
Mining of stibnite deposits begins, Lake George, New Brunswick. |
|
Antimony is found in the mineral stibnite and has a bluish white colour. |
|
Pliny incorrectly wrote that stibnite would give lead on heating, instead of antimony. |
