Minerals potassium

Potassium nitrate, essential in the manufacture of black gun powder, was produced by the Chinese, who had developed gun powder by the tenth century AD. The process involved the leaching of soil in which nitrogen from urine had combined with mineral potassium. By the early 1800s, potassium nitrate had become a strategic military chemical and was stiU produced, primarily in India, by using the ancient Chinese method. The caUche deposits in Chile are the only natural source of potassium nitrate (2). These deposits are not a rich source of potassium nitrate, purifying only to about 14% as K O.

The Berlin glass and porcelain technologist J. H. Pott believed that pyrolusite consisted of phlogiston and an earth somewhat like that in alum (58). In 1740 he prepared chameleon mineral (potassium permanganate ) and other compounds from it and showed that iron is not a constituent of pure pyrolusite (13).

SYLVITEA. A mineral, potassium chloride, KC1, occurring in cubes, or as cubes modified by octahedra. Sylvite is therefore isometric. It has a perfect cubic cleavage uneven fracture is brittle hardness. 2 specific gravity, 1.9 luster, vitreous colorless when pure but may be white, bluish, yellowish or reddish due to impurities. It is soluble in water. It is much rarer than halite and has been found as sublimates at Mt. Vesuvius and as bedded deposits al Slassfurl, Genii any. Extensive deposits occur in sedimentary deposits in the Permian basin of southwestern New Mexico, near Carlsbad, in die United States. 

Potassium-40, which has a half-life of 1.28 billion years, represents only about 0.012% of the potassium present in Earth today. Potassium-40 is useful for dating ancient rocks and minerals. Potassium-40 produces two different isotopes in its radioactive decay. About 11% of the potassium-40 in a mineral decays to argon-40 by emitting a positron.

At this time, purified potassium carbonate was primarily of value as an ingredient in glass making. The discovery of mineral potassium chloride at Stassfurt, Germany, in 1852, rapidly provided competition to the wood ash leachate industry since this mineral could be readily converted to potassium carbonate by the Leblanc process, which was already in commercial scale oper-...

As a mineral, potassium nitrate forms crusts on the surfaces of rocks and stone walls, and occurs as a component of surface soil in Spain, Iran, Egypt and India. In the US it occurs in loose soil in the Hmestone caves of Kentucky, Tennessee and the Mississippi Valley. 

Potassium Depletion. Deficiencies of potassium rarely result from dietary lack of the mineral. Potassium is lost whenever muscle is broken down owing to starvation, malnutrition, or injury since it is tied to protein inside cells. Crash diets, diarrhea, vomiting, geistric suction, diabetic acidosis, and burns also induce potassium loss from the body. Also lean tissue growth increases the need for potassium. A potassium-depleted individual may display irregular heart function, muscle weakness, irritability, paralysis, nausea, vomiting, diarrhea, and swollen abdomen.
