Production
Zinc sulfide is usually produced from waste materials from other applications. Typical sources include smelter, slag, and pickle liquors. It is also a by-product of the synthesis of ammonia from methane where zinc oxide is used to scavenge hydrogen sulfide impurities in the natural gas:
- ZnO + H2S → ZnS + H2O

Famous quotes containing the word production:
“The heart of man ever finds a constant succession of passions, so that the destroying and pulling down of one proves generally to be nothing else but the production and the setting up of another.”
—François, Duc De La Rochefoucauld (1613–1680)
“The problem of culture is seldom grasped correctly. The goal of a culture is not the greatest possible happiness of a people, nor is it the unhindered development of all their talents; instead, culture shows itself in the correct proportion of these developments. Its aim points beyond earthly happiness: the production of great works is the aim of culture.”
—Friedrich Nietzsche (1844–1900)
“The repossession by women of our bodies will bring far more essential change to human society than the seizing of the means of production by workers.”
—Adrienne Rich (b. 1929)
