A theoretical procedure has been developed with the aim of obtaining an accurate and rapid estimation of the degree of crystallisation in jarosite glasses by measuring the densities of the parent glass and, after the thermal treatment, of the glass-ceramic. Compositions were prepared by mixing jarosite waste with granite scraps and glass cullet, yielding three di€erent glass-batchs, melted at 1...

The jarosite family of minerals are part the alunite supergroup with general formula AB3(TO4)2(OH)6. Jarosite known to incorporate silver (Ag), but extent which this occurs, and at what temperature range, is not well constrained. To address knowledge gap, compounds A site filled K, Na, Ag H3O were synthesised 22 °C, 97 °C 140 simulate low-, moderate- high-temperature environments, respectively....

Hydroxy-based polyanionic cathode materials are reviewed for (post) Li-ion batteries with a special focus on the hydroxyphosphate, hydroxysulfate and jarosite classes of insertion host materials.

Bacterial leaching of an As-containing pyrite concentrate produced acidic (pH < 1) leachates. During the leaching, the bacteria solubilized both As and Fe, and these two elements were distributed in solution-phase and solid-phase products. Jarosite and scorodite were the exclusive crystalline products in precipitate samples from the bacterial leaching of the sulfide concentrate.

In this work, the geochemical characterization of olivine-phyric Martian shergottite LAR 12095 was performed by using two complementary analytical techniques: micro-Raman and micro-energy dispersive X-ray fluorescence spectroscopies. Thanks to methodology, olivine, pyroxene, ilmenite were detected as primary minerals from Mars. Maskelynite, hematite, anatase, chromite, merrillite, oxidized mack...
