lepidolite

Rubidium is present as a minor component in lepidolite.

There was lepidolite here, chock-full of lithium and run through with gallium as well.

He claimed to have found element 87, now called francium, in pollucite and lepidolite.

Lepidolite contains between 0.3% and 3.5% rubidium, and is the commercial source of the element.

Arfwedson later showed that this same element was present in the minerals spodumene and lepidolite.

Lithium is present as spodumene or lepidolite within pegmatite.

Another significant mineral of lithium is lepidolite.

Occurs in lithium-bearing pegmatites with spodumene, lepidolite, and tourmaline.

It was a year before he found anything worth spitting at, and even that was only a scratchy handful of lepidolite, lithium ore.

Other by-products produced included lepidolite, amblygonite (used for conversion to lithium chemicals) and spodumene.

Associated minerals include: quartz, albite, petalite, eucryptite, lepidolite and beryl.

It occurs naturally in the minerals leucite, pollucite, carnallite, zinnwaldite, and lepidolite.

Associated mineral species include elbaite, lepidolite, spodumene, columbite-tantalite, wodginite, and microlite.

It is usually associated with lepidolite, beryl, quartz, albite, amblygonite, and spodumene of pegmatitic origin.

It is commonly associated with topaz, cassiterite, wolframite, lepidolite, spodumene, beryl, tourmaline, and fluorite.

Association minerals include: albite, lepidolite, topaz, beryl, tourmaline, spessartine, tantalite and fluorite.

Amblygonite occurs with spodumene, apatite, lepidolite, tourmaline, and other lithium-bearing minerals in pegmatite veins.

Its typical occurrence is in lithium-rich pegmatites in association with albite, spodumene, petalite, amblygonite, lepidolite and quartz.

"Look at this, I mean, just look at this," he said, stroking a pink and lavender lepidolite sphere he found at a mine in Portland.

Zone pegmatite ore bodies containing mineable quantities of caesium as pollucite or the lithium minerals lepidolite are also a source for rubidium as a by-product.

In 1930, Fred Allison of the Alabama Polytechnic Institute claimed to have discovered element 87 when analyzing pollucite and lepidolite using his magneto-optical machine.

Rubidium is discovered by Robert Bunsen and Gustav Kirchhoff, in Heidelberg, Germany, in the mineral lepidolite through the use of their spectroscope.

Then came the time he came across something remotely promising, a tiny asteroid that held swirls of lepidolite and pollucite and spodumene and half a dozen other interesting ores.

A major source of rubidium is lepidolite, KLiAl(Al,Si)O(F,OH), wherein Rb sometimes replaces K.

In 1861 Robert Bunsen and Gustav Kirchhoff extracted 150 kg of lepidolite and yielded a few grams of rubidium salts for analysis, and therefore discovered the new element rubidium.
