Production
Potassium chloride occurs naturally as sylvite, and it can be extracted from sylvinite. It is also extracted from salt water and can be manufactured by crystallization from solution, flotation or electrostatic separation from suitable minerals. It is a by-product of the making of nitric acid from potassium nitrate and hydrochloric acid.

Famous quotes containing the word production:
“Every production of an artist should be the expression of an adventure of his soul.”
—W. Somerset Maugham (18741965)
“[T]he asphaltum contains an exactly requisite amount of sulphides for production of rubber tires. This brown material also contains ichthyol, a medicinal preparation used externally, in Websters clarifying phrase, as an alterant and discutient.”
—State of Utah, U.S. public relief program (1935-1943)
“An art whose limits depend on a moving image, mass audience, and industrial production is bound to differ from an art whose limits depend on language, a limited audience, and individual creation. In short, the filmed novel, in spite of certain resemblances, will inevitably become a different artistic entity from the novel on which it is based.”
—George Bluestone, U.S. educator, critic. The Limits of the Novel and the Limits of the Film, Novels Into Film, Johns Hopkins Press (1957)
