Lepidolite is associated with other lithium-bearing minerals like spodumene in pegmatite bodies. It is the major source of the alkali metal rubidium. [13] In 1861, Robert Bunsen and Gustav Kirchhoff extracted 150 kg (330 lb) of lepidolite to yield a few grams of rubidium salts for analysis, and therefore discovered the new element rubidium. [14 ...
The International Mineralogical Association is the international group that recognises new minerals and new mineral names; however, minerals discovered before 1959 did not go through the official naming procedure, although some minerals published previously have been either confirmed or discredited since that date.

Operations were simple, using a crew of four men to mine and hand sort the ore, which was taken out on "Beryl", the mine's mule. Production totaled 690 tons of high-grade ore with 11.2% beryllium oxide and 184 tons of lower-grade ore with 5.5% beryllium oxide, as well as small production of lepidolite. [2]
Iron was never smelted by Native Americans, thus the New World never entered a proper "Iron Age" before European discovery, and the term is not used of the Americas. But there was limited use of native (unsmelted) iron ore, from magnetite, iron pyrite and ilmenite (iron–titanium), especially in the Andes (Chavin and Moche cultures) and ...

Pollucite is a zeolite mineral with the formula (Cs,Na) 2 Al 2 Si 4 O 12 ·2H 2 O with iron, calcium, rubidium and potassium as common substituting elements. It is important as a significant ore of caesium and sometimes rubidium. It forms a solid solution series with analcime.
