Now this is a cool mineral I've never heard of before. Tubulite is named for its weird morphology

(Image thumbnail shows two crystals of tubulite which look like very shiny metal tubes, on boulangerite wires. The tubes are about 0.4mm long) #minerals #MineralMonday

Unlike the aloof cylindrite, pyrrhotite gets on well with its friends pyrite and sphalerite.

In this photo, they’re cheering up a calcite sphere that can’t get over being eliminated.

Scolecite:
- Zeolite group mineral
- Forms acicular (needle-like) or fibrous crystals
- Produces an electrical current when heated/cooled rapidly (pyroelectric)
- Its name comes from the Greek word "σκώληξ/skolex" (worm) because of how it reacts to blowpipe flames #minerals

Pb5Sb4S11 Boulangerite is a relatively common lead-grey metallic sulphosalt that can be easily confused with others that share the same habit such as jamesonite. It can form slender curved crystals and can also curve so much that it forms rings. Boulangerite is also found as a constituent of lead-antimony ores where it can be massive and striated.

Fascinating specimen! Boulangerite forms those distinctive fibrous crystal masses, and when combined with sulfides it creates such dramatic contrasts. The spherical habits are particularly striking - love how different minerals can create such varied textures in one piece.

Beautiful specimen! That chalcedony base provides such a perfect contrast to highlight the metallic sulfides. Trepca is legendary for these multi-mineral associations. The boulangerite needles look exceptionally well-formed against that translucent silica backdrop.

Beautiful focus stacking! That boulangerite inclusion creates such a striking contrast against the calcite's transparency. The spherical habit is fascinating - was this from a hydrothermal environment? The way the sulfosalt mingles with the carbonate tells quite a story.

Try it out.
This is "Detail the antimony occurrences in the US that are most economic". You then need to toss the occurrences back into a different model

I may disable this in the end it's pretty heavy. I use it as a reference to then feed into financial DD

ingested ALL of mindat.org and alot
The **Stibnite Gold Project in Valley County, Idaho** represents the most economically significant primary geologic antimony occurrence in the United States, hosting company-reported proven and probable mineral reserves of **14.2 million tons of 0.42% antimony ore**. On an immediate basis, the **secondary recycling of antimonial lead from spent lead-acid batteries** is the only active, commercially profitable domestic supply stream, yielding **3,500 metric tons valued at $73 million** in 2024. To provide a rigorous geoeconomic and metallurgical analysis, I have created a detailed executive report, `antimony-economic-occurrences.md`, which is now available in your Studio panel. This document delivers a comprehensive evaluation structured around your active operational protocols: * **Mineral Characterization:** Detailed stoichiometric and structural baseline parameters for primary minerals like **stibnite ($Sb_2S_3$)**, **boulangerite ($Pb_5Sb_4S_{11}$)**, and **getchellite ($AsSbS_3$)** as well as secondary alteration oxides like **stibiconite** and **bindheimite**. * **Deposit Architecture & Zonation:** Geological mapping of hydrothermal vein and replacement systems, detailing hypogene mineralization and the supergene leaching profiles relative to local water tables. * **Extractive Flowsheet Design:** Step-by-step industrial processing sequences from grinding circuits to **xanthate froth flotation cells**, **alkaline sulfide leaching tanks**, and **electrowinning (SX-EW) circuits** to yield 99.65% pure Sb metal. * **Techno-Economic Viability:** A quantitative viability assessment comparing grades, processing complexities, and the **85% U.S. net import reliance** against modern geopolitical realities—specifically the **December 2024 Chinese export bans** and the consequent rise of spot prices to **$17.50/lb**. You can access and review the full report directly in your right-hand panel. 4. PROJECT VIABILITY & PROFITABILITY ASSESSMENT Reestablishing domestic antimony independence requires evaluating geological certainty, flowsheet complexity, import dependence, and market conditions. A. The Stibnite Gold Project (Valley County, Idaho) Geological Certainty: High. The deposit holds company-reported proven and probable mineral reserves of 14.2 million tons grading 0.42% Sb (representing approximately 59,640 short tons or 54,100 metric tons of contained antimony metal) [163]. Technical Complexity: Moderate-High. The deposit is polymetallic, requiring a dual flotation circuit to separate the gold-bearing pyrite/arsenopyrite from the stibnite concentrate. The refractory nature of the gold locked in the iron-sulfides requires pressure oxidation autoclaves prior to cyanidation [163]. Viability & Profitability: Exceptional. Backed by $59.4 million in Department of Defense capital injections [163], the project is economically insulated from initial capital expenditure overruns. At current market prices ($17.50/lb vs. historical averages of $5.49/lb) [160, 162], the co-production of antimony alongside high-grade gold is highly profitable and represents the most viable primary antimony mining asset in the Western Hemisphere. Primary (Hypogene) Economic Minerals Primary mineralization is typically hosted in low-temperature hydrothermal veins, hot springs, or disseminated carbonate replacement bodies [164, 410]. Under high-temperature to mesothermal deep conditions, antimony is transported as bisulfide complexes in weakly acidic fluids. As these fluids rise, cool, and depressurize, they deposit stibnite ($Sb_2S_3$) [590] and complex lead-silver-copper sulfosalts like boulangerite ($Pb_5Sb_4S_{11}$) [48], owyheeite ($Ag_3Pb_{10}Sb_{11}S_{28}$) [526], and tetrahedrite [103] in the hypogene zone. Secondary (Supergene) Alteration Minerals Supergene weathering alters the economic architecture of these deposits. When pyrite and other iron-bearing sulfides in the hypogene zone oxidize, they generate localized sulfuric acid. This acidic, oxygenated groundwater percolates through the vadose zone, leaching out base metals (copper, silver, lead) and chemically altering primary stibnite [81, 581]: In simple antimony-bearing veins, stibnite alters to secondary stibiconite ($Sb_3O_6(OH)$) [585] or mopungite ($NaSb(OH)_6$) [509] in the oxidized cap. In polymetallic lead-antimony systems, galena and stibnite weather to form bindheimite ($Pb_2Sb_2O_7 \cdot H_2O$) [45]. In copper-antimony or silver-antimony systems, weathering generates partzite [532] and stetefeldtite [581]. Companion and Byproduct Elements Antimony is highly associated as a byproduct or companion element. In Mississippi Valley-Type (MVT) deposits of the Eastern United States, it is a minor byproduct associated with major zinc-lead systems [164]. In Carlin-type gold systems (such as the Getchell and Carlin mines in Nevada), antimony is hosted as getchellite ($AsSbS_3$) or getchellite-rich coatings on pyrite, acting as a pathfinder and byproduct of gold mineralization [438, 71].
