Alunite Crystal Chemistry - Mineral Processing Metallurgy

08/04/2018  Alunite is a semisoluble salt type mineral and when brought in contact with water it will extensively react with water to yield various aluminum and potassium species. The equilibrium abundance of these species has been calculated as a function of pH by using the available equilibrium data which include the following reactions. Each of the above equilibria gives a nonlinear equation.

ALUNITE (Potassium Aluminum Sulfate Hydroxide)

Alunite forms from the action of sulfuric acids upon potassium rich feldspars in a process called "alunitization". The sulfuric acids accompany hydrothermal solutions, usually rich in certain ore metals. These solutions can result in large bodies of alunite, making alunite a rock forming mineral. As such, alunite can easily be mistaken for massive rock forming dolomite or limestone . An acid ...

The Science of Mineral Processing faces a great challenge. As the population of the world doubles and re-doubles there is a parallel need for raw materials of all types to meet the needs of all nations. This need for raw materials actually exceeds the population growth for there is an ever increasing standard of living throughout the world. The increase in the living standard has its own ...

Alunite mineral Britannica

Alunite, also called Alum Stone, a widespread rock-forming sulfate mineral that occupies pockets or seams in volcanic rocks such as rhyolites, trachytes, and andesites, where it presumably formed through their chemical reaction with escaping sulfurous vapours. It has been used as a source of potash (during World War I) and as a source of alumina (during World War II); in Europe it was once ...

High-temperature roasting of alunite in the presence of K2CO3 gives rise to a reaction that results in up to an 80% recovery of its potassium content as K2SO4 by leaching of the roasted mixture. K2SO4 is also generated from the reaction between the added K2CO3 and the S03 driven off during roasting of the alunite. This limits the environmental and corrosive problems involved in the thermal ...

Mineral processing - Wikipedia

Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the ...
