Production
Bromine production is rather dynamic and has increased sixfold since the 1960s. Approximately 556,000 tonnes (worth around US $2.5 billion) was produced in 2007 worldwide, with the predominant contribution from the United States (226,000 t) and Israel (210,000 t). US production was excluded from the United States Geological Survey after 2007, and from the 380,000 tonnes mined by other countries in 2010, 140,000 t were produced by China, 130,000 t by Israel and 80,000 t by Jordan.
Bromide-rich brines are treated with chlorine gas, flushing through with air. In this treatment, bromide anions are oxidized to bromine by the chlorine gas.
- 2 Br− + Cl2 → 2 Cl− + Br2

Famous quotes containing the word production:
“Just as modern mass production requires the standardization of commodities, so the social process requires standardization of man, and this standardization is called equality.”
—Erich Fromm (1900–1980)
“From the war of nature, from famine and death, the most exalted object which we are capable of conceiving, namely, the production of the higher animals, directly follows. There is grandeur in this view of life, with its several powers, having been breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.”
—Charles Darwin (1809–1882)
“... if the production of any commodity necessitates the sacrifice of human life, society should do without that commodity, but it can not do without that life.”
—Emma Goldman (1869–1940)
