Gallium does not occur as a free element in nature, but rather as gallium(III) compounds in trace amounts in zinc ores (such as sphalerite) and in bauxite. Elemental gallium is a liquid at temperatures greater than 29.76 °C (85.57 °F), and will melt in a person's hands at normal human body temperature of 37.0 °C (98.6 °F).
It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite ( Al(OH) 3 ), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite ( Fe 2 O 3 ), the aluminium clay mineral kaolinite ( Al 2 Si 2 O 5 (OH) 4 ) and small amounts of anatase ...
Production of some products is highly concentrated in a few countries, China, the leading producer of wheat and ramie in 2013, produces 95% of the world's ramie fiber but only 17% of the world's wheat. Products with more evenly distributed production see more frequent changes in the ranking of the top producers.

The country was also the largest tin exporter globally, with Indonesian exports making up 32 percent of the international trade in 2020, worth US$1.11 billion. [15] Around 90 percent of national production originated from Bangka and Belitung, with smaller amounts being mined in Riau , Riau Islands , and West Kalimantan . [ 14 ]
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.
The mineral industry of Peru has played an important role in the nation's history and been integral to the country's economic growth for several decades. [1] The industry has also contributed to environmental degradation and environmental injustice; [2] and is a source of environmental conflicts that shape public debate on good governance and development.
