Production of potash in the United States increased slightly compared with that of 2001 and was approximately 1.2 million metric tons (Mt) of potassium oxide (K2O) equivalent (table 1) according to the U.S. Geological Survey (USGS), which developed domestic potash data from semiannual voluntary canvasses of U.S. operations.  Of the seven operations canvassed for both semiannual surveys, six responded.  Data were estimated for the nonrespondent for both surveys.  Data from the responding operators were estimated to represent about 98% of the total production listed in table 1.  There were five U.S. companies producing potash throughout the year from seven operations in three States.  Most of the domestic production was from southeastern New Mexico, where one company operated two mines and a second company operated one mine with multiple products.  The second company also operated a deep solution mine in Michigan.  The third State with potash production was Utah with three companies producing from three operations

Local:
Potassium Hydroxide, commonly called caustic potash with formula KOH, is a caustic compound of strong alkaline chemical dissolving readily in water, giving off much heat and forming a caustic solution. It is a white deliquescent solid in the form of pellets obtained by concentration of purified electrolytic potassium hydroxide solution with very low chloride content. It reacts violently with acid and is corrosive in moist air toward metals such as zinc, aluminium, tin and lead forming a combustible, explosive gas. It absorbs rapidly carbon dioxide and water from air. Contact with moisture or water will generate heat. Sodium hydroxide (Caustic soda) and potassium hydroxide (Caustic potash) are the two most important caustics. They are closely resembles in chemical properties and applications, e.g., in manufacturing liquid soap, in bleaching, and in manufacturing chemicals. Potassium hydroxide is the largest-volume potassium chemical for non-fertilizer use. Potassium Hydroxide is used in chemical manufacturing including potassium carbonate and other potassium chemicals, fertilizers, phosphates, agrochemicals, alkaline batteries and dyes.
APPLICATIONS: Potassium Hydroxide is used in chemical manufacturing including potassium carbonate and other potassium chemicals, fertilizers, phosphates, agrochemicals, alkaline batteries and dyes. It is also widely used in soap and bleaching industry.
