The stibnite is liquated out at a low heat and drips from the upper to the lower pot. |
The metal can also be obtained by conversion of stibnite to the oxide, followed by reduction with carbon. |
The metallic form is considered to be relatively inactive whereas stibnite is extremely toxic to humans. |
The cleavage planes between prismatic stibnite crystals have been infilled by sphalerite. |
High-grade or enriched stibnite reacts directly with scrap iron in the molten state, liberating antimony metal. |
There were shops full of green and purple fluorite, ferberite and arsenopyrite, and spessartine and stibnite. |
