In 2017, the world's production of low-grade gallium was c. 315 tons—an increase of 15% from 2016. China, Japan, South Korea, Russia, and Ukraine were the leading producers, while Germany ceased primary production of gallium in 2016. The yield of high-purity gallium was ca. 180 tons, mostly originating from China, Japan, Slovakia, UK and U.S.

Crystals of 99.999% gallium, grown and photographed by myself in February 2003. These particular crystals took about 45 minutes to grow, sitting in a plastic dish near a cool window. The lumpiness on the surface of these crystals is caused mainly by me shifting the dish around to monitor the progression of the crystal growth.
The resulting production of 71 Ge was calculated in 2005 to be 79% of expected, [5] confirming an earlier (1998) estimate from one of the experiments on GALLEX (another gave results indistinguishable from 100%, similarly to the Cr experiment on SAGE). [6] [7] This discrepancy soon became known as the gallium anomaly.
Reddish-brown bauxite Bauxite with US penny for comparison QEMSCAN mineral maps of bauxite ore-forming pisoliths. Bauxite (/ ˈ b ɔː k s aɪ t /) is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium.
Gallium(I) oxide is a brown-black diamagnetic solid which is resistant to further oxidation in dry air. It starts decomposing upon heating at temperatures above 500 °C, and the decomposition rate depends on the atmosphere (vacuum, inert gas, air).
