(2001)The growth of K-jarosite was evaluated using scanning electron microscopy (SEM), atomic force microscopy (AFM), and molecular simulations. SEM micrographs show crystals with almost quadratic and, to a minor extent, triangular ...
-
(2006)Jarosite [KFe3(SO4)2(OH)6] is a mineral that is common in acidic, sulphate-rich environments, such as acid sulphate soils derived from pyrite-bearing sediments, weathering zones of sulphide ore deposits and acid mine or ...
-
(2006)Gold extraction at the Macraes gold mine in New Zealand involves concentration of pyrite and arsenopyrite, oxidation of those sulphides, then cyanidation. The ore concentrate is predominantly Otago Schist host rock (andesitic ...
-
(2006)Alunite and jarosite from Goldfield, Nevada, show spectacular relationships between early alunite and later jarosite. In some cases, jarosite overgrows alunite with the same crystallographic orientation and sharp contacts. ...

(2006)Schwertmannite is a ubiquitous mineral formed from acid rock drainage (ARD), and plays a major role in controlling the water chemistry of many acid streams. The formation of schwertmannite was investigated in the acid ...

(2006)The presence of jarosite - a hydrous iron sulfate - at Meridiani Planum supports the past existence of water on Mars surface. Thermodynamic calculations suggest that jarosite should transform to ferric oxyhydroxides in ...
