One immediate consequence was that in 1842 he patented a manure formed by treating phosphates with sulphuric acid, and thus was the first to create the artificial manure industry. [10] In the succeeding year he enlisted the services of Joseph Henry Gilbert , who had studied under Liebig at the University of Giessen , as director of research at ...
John T. Arundel and Co. was engaged in Pacific trading of phosphates, copra, and pearl shell. While working in the company's Sydney office in 1899 Ellis determined that a large rock from Nauru being used as a doorstop was rich in phosphate. Following the discovery Ellis traveled to Ocean Island and Nauru and confirmed the discovery.
The phosphate mining industry employed 2,200 people. The value of phosphate rock mined was US$2.2 ... The North Carolina phosphate deposit was discovered in 1955. [6]
Under the food production regime in developed countries, shortages of rock phosphate could lead to shortages of inorganic fertilizer, which could in turn reduce the global food production. [ 95 ] Economists have pointed out that price fluctuations of rock phosphate do not necessarily indicate peak phosphorus, as these have already occurred due ...
Ellis' discovery of phosphate excited John T. Arundel of the Pacific Islands Company and the company decided to pursue rights and access to Nauru's lucrative resource. The negotiations to pursue rights to the phosphate involved four parties: the British and German governments, the newly reorganised Pacific Phosphate Company, and Jaluit-Gesellschaft (a German mining company that had been ...
Phosphorus must have been awe-inspiring to an alchemist: it was a product of man, and seeming to glow with a "life force" that did not diminish over time (and did not need re-exposure to light like the previously discovered Bologna Stone). Brand kept his discovery secret, as alchemists of the time did, and worked with the phosphorus trying ...
In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid, a.k.a. phosphoric acid H 3 PO 4. The phosphate or orthophosphate ion [PO 4] 3− is derived from phosphoric acid by the removal of three protons H +.
A sodium phosphate is a generic variety of salts of sodium (Na +) and phosphate (PO 3− 4). Phosphate also forms families or condensed anions including di-, tri-, tetra-, and polyphosphates . Most of these salts are known in both anhydrous (water-free) and hydrated forms.
