How much does stibnite cost?
A metric dry ton of iron sells for around $93, while this past summer, some stibnite crystals—weighing a few ounces—sold for $5,250 at Heritage Auctions.
Is stibnite toxic?
Stibnite is a toxic antimony sulfide mineral with an orthorhombic crystal lattice and a source of metalloid antimony. Stibnite paste has been used for thousands of years for cosmetics to darken eyebrows and lashes. The mineral was also used to make eating utensils, causing poisoning from antimony ingestion.
Is stibnite safe to handle?
‘Some of the minerals are extremely toxic,’ Lu explains, ‘so we have to wear gloves and a mask when handling them’. For example, stibnite contains antimony, which if ingested can cause symptoms similar to those from arsenic poisoning. If not handled carefully, it could have caused the conservation team serious harm.
What is the story of stibnite?
The Stibnite Gold Project site is one of the most historic mining districts in all of Idaho. Miners first started looking for gold at the site before 1900. Eventually, multiple mining companies were operating in the area and by 1932 the Bradley Mining installed a mill and started developing more robust operations.
What is stibnite gold?
The Stibnite Gold Project has the largest known antimony resource in the U.S. The project is one of the top 10 gold deposits in the U.S. We will recover more than 4 million ounces of gold over the 12 years projected for the life-of-mine.
