witherite

The rarity of witherite may favor baryte as the most likely source.

Up to this time witherite was considered worthless and used as rat poison by locals.

He also came to the conclusion that it was distinct from the witherite and contained a new earth (neue Grunderde).

Settlingstones, a major producer of witherite, in Northumberland (Dunham, 1948)

The mineral witherite (barium carbonate) was discovered in spoil from the mines in the 18th century.

The only other commercial source is far less important than barite; it is witherite, a barium carbonate mineral.

Barium carbonate occurs as witherite.

Barium is found as barium sulfate (barite) and barium carbonate (witherite) in the ground.

The barium source was either witherite (BaCO) or baryte (BaSO).

Fluorite and galena are the main ore minerals with subsidiary, but locally important, baryte, calcite, sphalerite, witherite, chalcopyrite and quartz.

There are also deposits of Fluorite, Barite, Witherite, Calcite, Dolomite and Barytocalcite.

It is commonly occurs in rocks that contain calcite, quartz, tremolite, witherite, phlogopite, diopside, minor amounts of forsterite and taramellite.

Barium carbonate (BaCO), also known as witherite, is a chemical compound used in rat poison, bricks, ceramic glazes and cement.

At the type locality at Brownley Hill, alstonite occurs in low-temperature lead-zinc hydrothermal deposits associated with witherite, calcite and baryte.

Barytocalcite often forms oriented growths on baryte, and calcite, witherite and baryte can be epitaxial on barytocalcite.

It was later shown to be barium carbonate and in 1789 the eminent German geologist Abraham Gottlob Werner named the mineral Witherite in his honour.

The reserves of mercury, antimony, lead, zinc, gold, barite, witherite, slate tile, cement, limestone, turquoise are on the first rank of China or Shaanxi Province.

Barium chloride can be prepared from barium hydroxide or barium carbonate, with barium carbonate being found naturally as the mineral witherite.

The most common naturally occurring minerals are the very insoluble barium sulfate, BaSO (barite), and barium carbonate, BaCO(witherite).

The source of barium in the glass in not clear; however it is possible that ancient Chinese glassmakers used witherite (a mineral form of barium carbonate) as an ingredient.

He named the mineral strontianite (strontium carbonate) and made clear that it was distinct from the witherite (barium carbonate) and stated that it contained a new element.

Gneissic banded rocks contain the mineral, which has been shown to be associated with witherite, sanbornite, and celsian in samples (with quartz-rich and gillespite-rich bands) from Incline.

At Foster's Hush, workings of a mineral-rich vein in the Great Limestone and Tuft Sandstone have exposed mineralisation of a rare mineral, witherite.

USA: Tiny sharp pseudohexagonal dipyramids of alstonite with benstonite and more commonly with witherite are found at the Minerva Mine, Cave-In-Rock, Illinois.

Furthermore, the reserves of mercury and slate tile tops China, and the reserves of antimony, alluvial gold, barite, witherite, slate tile are on the top of Shaanxi.
