Of the seven operations canvassed for both semiannual </p><p>surveys, six responded. Data were estimated for the nonrespondent for both surveys. Data from the </p><p>responding operators were estimated to represent about 98% of the total production listed in table 1. </p><p> There were five U.S. companies producing potash throughout the year from seven operations in </p><p>three States. Most of the domestic production was from southeastern New Mexico, where one </p><p>company operated two mines and a second company operated one mine with multiple products. </p><p> The second company also operated a deep solution mine in Michigan. The third State with potash </p><p>production was Utah with three companies producing from three operations </p><p>Local: </p><p>Potassium Hydroxide, commonly called caustic potash with formula KOH, is a caustic compound of </p><p>strong alkaline chemical dissolving readily in water, giving off much heat and forming a caustic </p><p>solution. It is a white deliquescent solid in the form of pellets obtained by concentration of purified </p><p>electrolytic potassium hydroxide solution with very low chloride content. It reacts violently with acid </p><p>and is corrosive in moist air toward metals such as zinc, aluminium, tin and lead forming a </p><p>combustible, explosive gas. It absorbs rapidly carbon dioxide and water from air. Contact with </p><p>moisture or water will generate heat. Sodium hydroxide (Caustic soda) and potassium hydroxide </p><p>(Caustic potash) are the two most important caustics. They are closely resembles in chemical </p><p>properties and applications, e.g., in manufacturing liquid soap, in bleaching, and in manufacturing </p><p>chemicals. Potassium hydroxide is the largest-volume potassium chemical for non-fertilizer use. </p><p>Potassium Hydroxide is used in chemical manufacturing including potassium carbonate and other </p><p>potassium chemicals, fertilizers, phosphates, agrochemicals, alkaline batteries and dyes. </p><p>APPLICATIONS: Potassium Hydroxide is used in chemical manufacturing including potassium </p><p>carbonate and other potassium chemicals, fertilizers, phosphates, agrochemicals, alkaline batteries </p><p>;q=Potassium%20hydroxide;term=1310-58-3;max_hit=1000&amp;dbkey=kegg&amp;keywords=Potassium%20hydroxide;queryBean.stars=3&amp;queryBean.stars=-1</p></li><li><p>and dyes.
