Jun 26, 2014· Potash mining. Today, potash comes from either underground or solution mining. Underground potash deposits come from evaporated sea beds. Boring machines dig out the ore, which is transported to the surface to the processing mill, where the raw ore is crushed and refined to extract the potassium salts.

Potash is produced in the United States from underground mines in New Mexico, solution mines in Michigan and Utah, and surface brines in Utah. Potash deposits in Arizona, Nevada, New Mexico, North Dakota and Utah are under development for solution mining. Total world production of potash in 2010 was 33.7 million metric tons potassium oxide.

May 27, 2015· After the water evaporated, the potassium salts crystallized into large beds of potash deposits. Over time, upheaval in the earth's crust buried these deposits under thousands of feet of earth and they become potash ore. The Paradox Basin, where the mines at Moab are located, is estimated to contain 2 billion tons of potash.
