      Mineral deposits of Canada: a synthesis of major deposit-types, district metallogeny, the evolution of geological provinces, and exploration methods Issue 5 of Special publication Authors.   Abstract. Sulfur isotope abundance data for minerals of the historically important alunite deposits of the Tolfa district indicate (1) compositional similarity between sulfates and sulfides (mean δS 34 values of + 4 and + 4 permil respectively), (2) negligible fractionation factors ( to ) for sulfate-sulfide mineral pairs, (3) two distinct sulfide isotopic populations Cited by:

The gold-alunite deposits are enclosed in areas of intense acid sulfate alteration and localized in ring and radial faults and fractures present in the east wall of the Lomilla caldera. Like other acid-sul- fate type deposits, the Rodalquilar gold-alunite deposits. Abstract. The problem of alunite formation is analyzed in the light of equilibrium with the species from which it forms. The results of several synthesis experiments show the yield of precipitate as a function of the initial physical and chemical by: 2.

Potash alunite is isomorphous with natro-alunite, a complete series of minera1s being known ranging from pure KAlSH20 to pure Na}AlSH The composition of pure potash alunite, or simply alunite as it will henceforth be designated, is as follows: K20 /o Al 37 oO/o S03 ~ H20 %.

Alunite is an analog of Jarosite, where aluminium replaces Fe 3+.Alunite occurs as a secondary mineral on iron sulfate ores. Alunite occurs as veins and replacement masses in trachyte, rhyolite, and similar potassium rich volcanic is formed by the action of sulfuric acid bearing solutions on these rocks during the oxidation and leaching of metal sulfide ry: Sulfate minerals.

Deposits of chalk-like alunite occur at other localities, notably at Carrickalinga Head in South Australia. Alunite is sometimes associated with valuable gold deposits. In volcanic regions it is not uncommon to find considerable areas of bleached and altered lavas which contain more or less alunite (KA12OSH2O), an earthy or compact.

The Alunite Gold Mine is in Henderson, Nevada. Historically the site has been associated with the Camp Alunite-Las Vegas Mining District which is now part of the Lake Mead National Recreation Area.

The ore mined is composed of potash. The Sonoran Desert of the Intermontane Plateaus characterize the geomorphology of the surrounding area.

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.

alunite was cogenetic with pyrite in any of these de- posits, and alunite veins cut pyrite-bearing rock (Fig. 2A). One of the major arguments presented for a hy- pogene origin for alunite in sediment-hosted micron gold deposits is the presence of coexisting (presumed cogenetic) barite and alunite.

In volcanic rocks which are more reduced than the hematite-magnetite oxygen buffer, the presence of alunite indicates high H 2 S activity if the fluid contained greater than molal total sulfur Cited by: Alunite KAl3(SO4)2(OH)6 c Mineral Data Publishing, version 1 Crystal Data: Hexagonal.

ACID SULFATION OF ALUNITE By L. J Froisland,1 M. ~ouden, 1 and D. Harbuck ABSTRACT The U.S. Bureau of Mines conducted laboratory studies on sulfuric acid (H2S04) digestion of alunite [KA1a(S04)z(OH)6] as a means for treating domestic deposits of this mineral. An alunite-jarosite solid solution series has been synthesized at 78' C./l atm., " C./1 atm, and ' C./ atm., with a molar ratio of K+ to total trivalent (Al-Fe) cation using HzSOr as solvent to prevent hydrolysis of ferric ions.

Alunite is also known as alumstone and is a source of the chemical known as alum, KAl(SO4)2 - alunite has also been used to recover potassium and aluminum. 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.
