HISTORIC SILVER & SULFIDES in BARITE: BULLDOG MINE, CREEDE

So here is a classic silver ore specimen of native silver, acanthite and other sulfides growing through a barite and quartz matrix that has been cut on one side but not polished to show the interior of the piece that comes from this old miners stash from the historic Bulldog Mine that was collected by the old miner back in the 1960s.

Barite mineral Britannica

Barite, also called barytes or heavy spar, the most common barium mineral, barium sulfate (BaSO 4).Barite occurs in hydrothermal ore veins (particularly those containing lead and silver), in sedimentary rocks such as limestone, in clay deposits formed by the weathering of limestone, in marine deposits, and in cavities in igneous rock.It commonly forms as large tabular crystals, as rosettelike

Barite: The mineral Barite information and pictures

Barite is the main ore of the element barium. It is also important in the manufacture of paper and rubber. Barite is also used in radiology for x-rays of the digestive system. When crushed, it is added to mud to form barium mud, which is poured into oil wells during drilling. A rich, white pigment was once made from crushed Barite.

Polymetallic replacement deposit Wikipedia

The metallic ore minerals are mostly in sulphides, such as galena, sphalerite, enargite, and argentite. Gangue minerals include quartz, pyrite, rhodochrosite, and barite. The mineralogy changes with distance from the intrusive rock. Closest to the intrusion is the copper-gold zone; next is the lead-silver zone, then the zinc-manganese zone.

Baryte Wikipedia

Baryte, barite or barytes (UK: / ˈ b ær ʌ ɪ t /, / ˈ b ɛər aɪ t / [citation needed]) is a mineral consisting of barium sulfate (Ba S O 4). Baryte is generally white or colorless, and is the main source of the element barium.The baryte group consists of baryte, celestine (strontium sulfate), anglesite (lead sulfate), and anhydrite (calcium sulfate). Baryte and celestine form a solid

Geology of the Barite Hill gold-silver deposit in the

Gold-silver-rich zones in the Main pit are partly coincident with lenses of siliceous barite rock, but not confined to them, and occur more commonly in pyrite-quartz-altered fragmental rock. The Main pit ore is stratigraphically overlain by a zone of base metal and barite enrichment, which is, in turn, overlain by a talc-tremolite alteration

Geochemistry of hydrothermal gold deposits: A review

Jul 01, 2011 The salinity and temperature of ore-forming fluids have wide ranges. Salinities of some ore-forming fluids are lower than sea water, whereas those in fluids forming porphyry deposits can reach 80 wt.% NaCl (Heinrich, 2007).The salinity and temperature of most hydrothermal fluid decrease during the late-stages of ore formation, suggesting either the attenuation of heat and fluid source or the

In 1995, the Meikle deposit was estimated to contain a remaining resource of 8412 kilotonnes of ore containing 187.47 tonnes of gold (Long and others, 1998).By the end of 1998, the mine had produced more than 1.5 million troy ounces of gold and more than 426,000 ounces of silver. 1996 proven and probable reserves were reported at 8.5 Mt grading 0.716 opt Au; with an additional1.4 Mt of

High-Grade Gold-Barite Ore, Goldfield, Nevada (103043)

High-grade gold-barite from the Sandstorm Mine in Goldfield, Nevada, approx 70 x 55 mm. Original collector identifies goldfieldite -- a copper-tellurium-sulfide, and bismuthinite -- a bismuth sulfide. These form the dark, silvery-gray clusters amidst a light tan background matrix of barite -- a barium sulfate.

Geology and Ore Genesis of Silver–Barite Mineralization in

Silver–barite ore was deposited as massive, open-space filling within listric faults in the Pickhandle Formation, while it is largely disseminated within siltstone of the Barstow Formation.

The calico silver-barite deposits near Barstow, California, are a potentially important resource. Exploration performed by two major mining companies outlined large tonnages of ore that assayed at 2 to 3 ounces of silver per ton and 7 to 15 percent barite. Laboratory beneficiation work was done by the Bureau of Mines on four samples to develop methods for recovering the silver and/or barite.
