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 ...
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 ...

The majority of the world's beryllium is sourced from non-gem quality beryl within pegmatite. [29] Tantalum, niobium, and rare-earth elements are sourced from a few pegmatites worldwide, such as the Greenbushes Pegmatite , [ 30 ] the Kibara Belt of Rwanda and Democratic Republic of the Congo , the Kenticha mine of Ethiopia the Alto Ligonha ...
It ranked 22 in the world in terms of iron ore production and 29th in gold production. The total value of mineral production in New Zealand was $1.5 billion in 2006 (excluding oil and gas). The most important metallic minerals produced are gold (10.62 tonnes), silver (27.2 tonnes) and titanomagnetite ironsand (2.15 million tonnes).
The haematite iron ore with the iron content of up to 60% was prospected in the middle of the 19th century. [7] The Swaziland Iron Ore Development Company (SIODC), owned by the Anglo-American Corporation, started mining of the deposit in 1964. [7] A ten-year contract with a Japanese company made it the largest consumer of the iron ore.
The artifacts recovered from this grave are variously made of wrought iron, cast iron, malleabilized cast iron, and quench-hardened steel, with only a few, probably ornamental, bronze weapons.
