Processing of potash ore

The hot leaching method of ore processing is based on the physicochemical properties of NaCl-KCl-H2O system. The main principle of this method is the different temperature-depending degree of solubility of the mineral components sylvite and halite: the high solubility of potassium chloride from ore by cycling solution at 115°C and the further crystallization of the valuable component on

Rubidium and Potassium Extraction from Granitic Rubidium

Thus far, little is known about the use of granitic rubidium ore for the extraction of rubidium. Herein, we examined the extractability of rubidium and potassium from granitic rubidium ore via sulfuric acid baking, reductive decomposition, and alkaline leaching. In addition, the extraction mechanism was studied by using interdisciplinary approaches based on the mineralogy and thermodynamics

Potash Wikipedia

Potash (especially potassium carbonate) has been used in bleaching textiles, making glass, ceramic, and making soap, since about AD 500.Potash was principally obtained by leaching the ashes of land and sea plants. Beginning in the 14th century potash was mined in Ethiopia.One of the world's largest deposits, 140 to 150 million tons, is located in the Tigray's Dallol area.

Potassium Wikipedia

Potassium is a chemical element with the symbol K (from Neo-Latin kalium) and atomic number 19. Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force. Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure. It was first isolated from potash, the ashes of plants, from which its name derives.
