Mining
Naturally occurring deposits of nahcolite (NaHCO3) are found in the Eocene-age (55.8–33.9 Ma) Green River Formation, Piceance Basin in Colorado. Nahcolite was deposited as beds during periods of high evaporation in the basin. It is commercially mined using in-situ leach techniques involving dissolution of the nahcolite by heated water that is pumped through the nahcolite beds and reconstituted through a natural cooling crystallization process.

Famous quotes containing the word mining:
“Any relation to the land, the habit of tilling it, or mining it, or even hunting on it, generates the feeling of patriotism. He who keeps shop on it, or he who merely uses it as a support to his desk and ledger, or to his manufactory, values it less.”
—Ralph Waldo Emerson (1803–1882)
“It’s a mining town in lotus land.”
—F. Scott Fitzgerald (1896–1940)
“In strict science, all persons underlie the same condition of an infinite remoteness. Shall we fear to cool our love by mining for the metaphysical foundation of this elysian temple? Shall I not be as real as the things I see? If I am, I shall not fear to know them for what they are.”
—Ralph Waldo Emerson (1803–1882)
