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.

Famous quotes containing the word production:
“I really know nothing more criminal, more mean, and more ridiculous than lying. It is the production either of malice, cowardice, or vanity; and generally misses of its aim in every one of these views; for lies are always detected, sooner or later.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“... 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)
“In the production of the necessaries of life Nature is ready enough to assist man.”
—Henry David Thoreau (1817–1862)
