Gallium trichloride is a common starting reagent for the formation of organogallium compounds, such as in carbogallation reactions. [44] Gallium trichloride reacts with lithium cyclopentadienide in diethyl ether to form the trigonal planar gallium cyclopentadienyl complex GaCp 3. Gallium(I) forms complexes with arene ligands such as ...
Kittilä mine is the biggest gold mine in Europe. Finland has the largest concentration and producer of gold in the European Union. [1] [2] The European mining industry has a long tradition. Although the continent's mining earns for a small share of GDP, it provides a large and significant share of the world-wide production. [3]

Bauxite is the main source of the rare metal gallium. [17] During the processing of bauxite to alumina in the Bayer process, gallium accumulates in the sodium hydroxide liquor. From this it can be extracted by a variety of methods. The most recent is the use of ion-exchange resin. [18]
Europe alone produced about 12 million tons of metallic wastes in 2012, and this amount tended to grow more than 4% a year (faster than municipal waste). However, fewer than 20 metals, of the 60 studied by experts of the UNEP, were recycled to more than 50% in the world. 34 compounds were recycled at lower than 1% of the total discarded as trash.
